Collada file format version 1.5 released

To anyone interested in alternatives to the long-antiquated VRML file format (used for Pocket PC or not), the Khronos Group has released the specification for the COLLADA 1.5 file format, which is freely available from its website. The new version adds support for B-reps (boundary representations) and kinematics, both targeted towards the CAD, automation and game industries. It also provides a new OpenGL ES 2.0 effects profile, expanded support for external shader effects systems, and a new file format - .zae, or Zipped Asset Exchange.

The Group has also released the 2nd Edition of its COLLADA 1.4.1 spec, which includes corrections, clarifications and enhanced explanations for transparency, animation, lighting, splines and skinning. “COLLADA 1.5 is a very significant release as it contains new functionality that enables completely new industries to use COLLADA – as well as expanding the use of this widely used standard in its traditional content-creation markets,” said Neil Trevett, president of Khronos.

“The industry momentum of COLLADA has now reached a critical tipping point – it has become a genuine lingua franca for 3D designers everywhere.” Marc Stevens, general manager of Softimage, and vice president of AVID Technology, added: “We see COLLADA as a key strategic component of our future. COLLADA is the only true open format that facilitates 3D data interchange. The latest release adds many features, including a referenced texture archive and support for real-time shaders—exemplifying how COLLADA is leading the way in open workflows.

Softimage recently implemented a rich content pipeline to the Crytek, CryENGINE 2, based completely on a COLLADA interchange; we’re fully committed to supporting the advancement of the COLLADA standard, which delivers the most productive work-flows for our SOFTIMAGEXSI customers.”

Various pre-SIGGRAPH product announcements

It used to be the case that software developers announced new products on the opening day of SIGGRAPH. This year however, several developers have jumped the gun, announcing product updates in the week preceding the show. The timing is presumably an attempt to ensure that the releases don‘t get lost in the blizzard of news announcements that ensues as harrassed journalists scurry to the press room on the first Monday.

Softimage and Caligari were first out of the blocks, unveiling XSI 7 and trueSpace 7.6 a full month before the show (now a free download, thanks to Microsoft‘s backing). Earlier this week, they were followed by The Pixel Farm, promoting true stereoscopic 3D tracking and updated camera solver in PFTrack 5.0; and e-on Software announcing that Vue 7 will be previewed at the show (same tools as Vue 6, but refined and updated).

This was followed by both Eyeon and Autodesk, announcing Fusion 6 and Mudbox 2009 and the 3ds Max 2009 Creativity Extension, respectively. Eyeon is also riding on the wave of interest in stereoscopic 3D workflows, adding a stereo compositing toolset and a complete new 3D system. The move follows The Foundry's lead in building stereo tools into Nuke 5.0, released earlier this year.

Meanwhile, Autodesk has unveiled Mudbox 2009, adding a new texture-painting toolset to the digital sculpting tool. Mudbox 2009 will also offer significant performance boosts and, unsurprisingly, improved normal and bump map interchange Autodesk‘s main 3D packages, Maya and 3ds Max.

The Creativity Extension to 3ds Max adds new particle operators (essentially the old Particle Tools Box 1 plug-in, formerly sold for $195, with a few bugfixes and better integration into the core software, we‘re told), a new geometry optimisation tool and support for multi-track audio. The release should go some way towards pacifying games and visual effects artists who felt that the new features 3ds Max 2009 were weighted too heavily towards visualisation professionals – those of them who are on subscription contracts, and can actually obtain it, at least.

Greeble plug-in CG community gallery

"A greeble or nurnie is a small piece of detailing added to break up the surface of an object to add visual interest to a surface or object, particularly in movie special effects."

Wikipedia

I've featured a self-made tutorial on the excellent Greeble 3D Studio Max plug-in before (on how to quickly generate a randon 3D urban environment, found here) but I was very pleased to find out today about http://www.greeblelicious.com/, a CG community gallery website devoted to Greeble artistry.

You may be asking yourself what the hell that is exactly and the best way to explain it is for you to see some of the samples for yourself... Greeble artwork can be absolutely stunning or it can be downright terrible but some of the examples on said website are indeed very inspiring (with some great 3D virtual cities in there too) and well worth checking out.

Bournemouth University students winners of the Google ‘International Model Your Campus Competition’

Phil Hazleton (BA Business Studies) and Alex Geeves (BSc Digital Media Development) wowed judges from the world of IT, architecture and design with their model of Bournemouth University's Talbot Campus at this year’s Google ‘International Model Your Campus Competition’.

They used Google SketchUp to create BU's campus buildings, which they geo-referenced in Google Earth and uploaded using the Google 3D Warehouse application. Commenting on the entry, the judges said: "They captured the right level of detail to efficiently reflect the character and complexity of the campuses they represented. The photo-texturing was exceptional – people, cars and vegetation were removed so that the building textures were plainly visible.”

Phil is over the moon with his success. He said: “To be one of the winners feels great. It’s great for BU too, as it will appear in Google Earth automatically whenever anyone is looking around the area.” BU is amongst seven winners worldwide, which include Peking University, University of Wisconsin-Madison, Stockholm University and Cardiff University.

You can check out or even download the model at http://sketchup.google.com/3dwarehouse/cldetails?mid=4fb3a8154ea11489d00c70bf72aa4ee1

CityEngine generates Rome in one day at SIGGRAPH and becomes available as a download

I have featured posts on this particular application before but at this year’s SIGGRAPH, a spectacular 3D recreation of ancient Rome (A.D. 320) will be revealed where revolutionary graphics technology has been applied to reconstruct the extremely detailed virtual urban environment.

Procedural Inc., an innovative software company located in Zurich, Switzerland, is home to arguably the world’s foremost procedural modeling technology. With the CityEngine, Procedural Inc.’s graphics experts have created a radically different 3D application that allows the modeling of cities up to 10 times faster than previous solutions, making automatic digital city creation possible for professional users. This makes it a compelling tool for the production of video games, feature films and television series, architectural visualizations and applications for the emerging 3D internet, where consumers expect richer, higher quality digital content for their dollar.

“Cities are huge, richly detailed artifacts that are often required in digital productions, and modeling them with existing tools can take several man years,” says Pascal Müller, CEO of Procedural Inc. “The CityEngine addresses these previously unsolved modeling problems by offering several procedural modeling tools for generating large-scale urban layouts, as well as a unique shape grammar for the efficient creation of detailed building models. With these tools, users not only experience a faster modeling experience, but one which allows them to create cityscapes that have never been seen before.”

Bernard Frischer, director of Rome Reborn says that “Our project involves the complete virtual reconstruction of the city at its zenith under Emperor Constantine, when it had about one million residents. To build by hand the corresponding 7,000 apartment buildings, family houses, public buildings and temples would have taken us forever; but CityEngine's power and flexibility made the process amazingly quick without sacrificing detail or quality. This allowed us to concentrate on modeling the unique monuments. The CityEngine also helps to quickly change the model as new scholarship or discoveries warrant.”

“After the Rome building designs had been specified in the CityEngine, generating and exporting the entire city model took exactly 1 hour and 55 minutes,” continues Müller. “Thus, Rome actually WAS built in one day… or, at least its digital counterpart was.” The release of CityEngine also marks the official debut of Procedural Inc. Founder and CEO Pascal Müller was formerly a researcher at ETH Zurich, where he pioneered the field of procedural urban modeling (with his series of SIGGRAPH publications about procedural urban modeling), which led to the creation of CityEngine.

In just six months, the Procedural engineering team under CTO Simon Schubiger transformed the research into a powerful industry application. Priced at $6,950 per license, there is also a free 30-day trial version, including example scenes, available for download at http://www.procedural.com/. Looking very forward to trying this one out, watch this space for a future post on that topic!

trueSpace available for free, tied to Virtual Earth content

An interesting development in urban modelling; Microsoft's Virtual Earth has been arguably lagging behind in terms of free tools for its community and content so its interesting that recently Microsoft announced, via Chris Pendleton's blog, that trueSpace, the previously $595 3D authoring package, is now free with the explicit aim of adding content into Virtual Earth.

Part of Chris's post mentions:

"As you'll recall, several months ago we acquired Caligari because of their advanced 3D toolset - trueSpace (among other assets). I've always felt sketchy about other 3D freeware, so starting today trueSpace 7.6 is now available for download.....FOR FREE! And, there is a direct connection into Live Search Maps so you can create SUPER high resolution 3D models using trueSpace, then right from the environment upload the model into Live Search Maps as a collection item. Once you've created your collection, you can import your collection into your Virtual Earth application and BAM you have your own custom 3D models in your Virtual Earth application. We'll host the models right in our 3D collections cloud..."

A Microsoft initiative to create a contender for Google SketchUp? Time can only tell...

Nokia's views and strategic plan on mobile gaming

As a great insight into the future of mobile gaming as seen by one of the current leading firms in the field at the moment, during his opening mobile keynote at the recent Develop conference at Brighton, UK, Nokia’s Aki Jarvilehto has predicted that the mobile market will be worth €4.2 by 2011 – with part of that growth driven by new games developed with 'disruptive technology' such as GPS and high-quality production values in mind.

He explained that the market had started to move beyond a world where the user-experience for discovering games, and the frustrating way developers have to produce SKUs for thousands of handsets, was “on par with getting punched in the face” and instead developers and publishers are now able to invest in the more innovative technologies available in new handsets. “Publishers are moving into [high quality mobile content investment],” he said, adding that perceptions in the industry were changing towards valuing better production values in games. At the same time, the opportunities for developers to self-publish their games on mobile devices were on the rise. “For you as a developer this means now is the right time to ask ‘how do I innovate?’”.

Before delving into the technologies that developers can innovate with, however, he added that those making mobile games should be aware that innovation works best when it satisfies consumer needs. “Innovation is a dirty word that gets overused often. I dislike innovation for innovation’s sake. It’s too easy to chase that next new feature. The guiding beacon for innovation should always be the consumer. When you are looking to take these technologies into use you stay focused on the consumer,” he said.

Jarvilehto then presented Nokia’s view on the market for mobile games, profiling six key demographics (quotes are examples of how each demographic would describe its playing habits. The segments are: Core Gamer (‘playing is part of my identity and I want to play and compete with others’), Web 2.0 (‘I want games which let me interact and communicate with my friends and other people’), personal development (‘I would play games that make me a better person’), casual gamer (‘I want to be entertained while I have a break or nothing else to do’), feminine games (‘I want to be entertained on my own terms) local content (‘I want to play games which resonate with my cultural background and are familiar to me’).

Jarvilehto added that there are “disruptive technologies which we have available” to satisfy these consumers. He also pointed to four Nokia products – cross-platform core gamer game Reset Generation, episodic camera game Dirk Dagger, user-generated content title Yamake and virtual pet Creebies – as examples that these innovations were possible. These games took advantage of some of the “hot technologies” which were or will soon be available in a variety of handsets – and not just Nokia ones.

CPU performance and memory on devices is improving such that it will soon be “taken for granted”, he said, adding that “game changing” 3D acceleration is on the rise and also makes TV-out more relevant in devices. Javilehto added that, in developing countries, “consumers will have their first high-end games experience via a portable device plugged into a TV”. Touchscreen is also something “[Nokia is] going to support at all prices points”, he said, adding that the same is true of accelerometers, possibly even magnetometers, and cross-platform functions “which will be shipping in most of our devices”.

But it was GPS he said offered the most immediate potential for mainstream innovation. “Nokia is taking GPS mainstream in a significant way,” he said, describing his company’s push behind this technology was on par with the way it pushed forward camera phones. Specifically, he said that GPS – married with the other new technologies – presented an opportunity for “super exciting” mixed reality games which drew from content in the real world, such as maps, to inform in-game content. “We’re looking into concepts that generate content from the city maps we have available. We’re finding ways of making gameplay relevant,” he said, saying such data could be used in a racing game, for instance, to drive a player’s emotional involvement in their game.

Torque game engine optimized for iPhone use

A piece of news interesting for everybody researching mobile graphics and mobile gaming; GarageGames has announced that its popular Torque engine now supports the iPhone. According to the press release, Torque developers are now able to use the engine's 2D and 3D functionality to create games for the iPhone (and presumably iPod Touch).

GarageGames Torque for the iPhone SDK includes a a full-featured WYSIWYG realtime editor, easy integration with many 3D modeling packages, a powerful scripting language and more. All this and you can develop your game on a PC and test your application on an iPhone emulation of your application using Apple's iPhone Developer SDK. GarageGames has provided additional iPhone-specific functionality for Torque with:
- Multi-touch Input Support
- Touchscreen Gesture Recognition
- iPhone Optimized Compressed Texture
- Advanced Character and Shape Animations

DirectX 11 announced by Microsoft

Microsoft has, as of today, revealed the first details on the latest version of its DirectX SDK at the Gamefest event in Seattle. Chief new features in version 11 are:

a) the new Compute Shader technology, which allows GPUs to be used for general purpose computing

b) support for tesselation, allowing models to be refined and smoother up-close

c) multi-threaded resource handling to help games utilise multi-processor set-ups more effectively

In a new twist, rather than require new hardware as DirectX 10 did, DirectX 11 will be completely compatible with DirectX 10 and 10.1 cards - but will, like its predecessor, only support the Windows Vista operating system.

Academic journals on computer games

Seeing that I have some recent results suitable for publication in a computer games journal (and also future research directions could potentially be in that field too), I decided to do a quick round-up of all available outlets in that field.

While there are not as many computer games journals as I would have hoped (computer games as a serious academic research topic is a relatively new excursion unfortunately), there's definitely enough of them to justify conducting publishable research in the area. Incidentally, the list is by no means exhaustive, please feel free to contact me if I have missed any out!

Taylor and Francis Young Researcher Focus Group

Yesterday I attended a Researcher Focus group event at publishing house Taylor and Francis' headquarters in Milton Park, Abingdon. Chaired by two senior academics, the day took the form of a structured discussion under a series of key headings. The intention was to gain a clear, accurate snapshot of current scholarly communication and research behaviours, particularly regarding social networking in academia and to ascertain the goals and aspirations of other young researchers.

There was also the chance to offer feedback on the publisher's online journal repository portal (found here) where I was personally very interested to see features such as iFirst implemented (a feature where journal articles are published immediately online as soon as they are accepted, rather than go through the usual 10-12 month wait, it would be fantastic if a trend like that takes off as a lot of research, particularly in technology-oriented fields, is sorely out of date by the time it gets published).

Cities XL, a brand new gaming take on the city-building gerne

CITIES XL™ is a brand new game which takes on the city-building genre in a fashion similar to Sim City. CITIES XL™, according to Monte Cristo, the developing team behind the title, will expand upon all the features that make city builders fun - such as shaping cities, managing the economy and caring for the needs of city inhabitants. Players can also take their game online and interact with thousands of others on massive persistent planets.

CITIES XL is scheduled for release first quarter of 2009 with online play based around the development of a new planet allowing community members to: a) build cities in a virtual world populated by other subscribers, allowing the creation of a living online community b) trade with others, specialize a city in specific activities such as tourism, entertainment, business development, recycling management and more c) visit other cities and host events for others to attend and enjoy d) cooperatively create a booming metropolis teeming with life and businesses e) participate in competitions and enjoy a calendar of events that will keep you coming back to your planet f) share your in-game experience with friends through a companion community website.

The second vid is a fascinating insight on how the 3D building models were created while the first a trailer of the game itself, for more information check out the official website at http://www.citiesxl.com/.

Mali-400 MP scalable multiprocessor graphics solution, high-end graphics for all mobile devices

As someone perpetually frustrated by the lack of decent 3D graphics cards on mobile devices, it is very exciting to hear that ARM announced a few days ago the ARM Mali-400 MP scalable multiprocessor graphics solution, capable of delivering performance of up to 1G pixels/s and enabling licensees to serve multiple product markets with the same architecture, while retaining the flexibility to choose the optimum power, performance and area configuration for their application. The Mali-400 MP architecture offers scalability and lower cost for developers and OEMs associated with platform fragmentation, as no changes are required to support one to four processors. "Architectural reuse of software and hardware components is of increasing importance to SoC developers," said Frank Dickson, co-founder and chief research officer, MultiMedia Intelligence.

"The scalability of the ARM Mali-400 MP GPU, from 300 million to over 1 billion pixels per second, will enable OEMs to deliver a wide range of market-leading products on the same underlying architecture, reducing their total cost of ownership and maximizing ROI."

The Mali-400 MP solution builds on ARM’s experience and knowledge gained in the ARM MPCore technology, implemented in the ARM11 MPCore and Cortex-A9 MPCore multicore processors, designed to reduce system bandwidth, optimize performance and reduce power consumption. Power consumption and area efficiency are key aspects of the Mali-400 MP GPU design. The ability to scale performance to meet different price points and power budgets allows the Mali-400 MP GPU to address the widest possible market while bringing significant cost benefits through utilizing the same single software stack across multiple devices.

Could this mean that, set by the Nokia N95 and iPhone trend (both devices with powerful 3D graphics capabilities), 2008/2009 could really finally be the year for quality mobile 3D? For more details check out http://www.arm.com/

Enkin, a new mobile location-based augmented reality research project

"Enkin", a new mobile AR project initiated by Max Braun and Rafael Spring, introduces a new handheld navigation concept. It displays location-based content in a unique way that bridges the gap between reality and classic map-like representations. It combines GPS, orientation sensors, 3D graphics, live video, several web services, and a novel user interface into an intuitive and light navigation system for mobile devices.

The very comprehensive video above speaks for itself, not only do you see the prototype in action but also how the system architecture is set up and other useful information. Quite possibly the best and most complete mobile location-based AR application I have seen so far...

Ubisoft acquires Sin City special effects firm

Ubisoft has heralded its acquisition of the VFX firm responsible for effect in movies such as Sin City and 300 as "a groundbreaking event for digital entertainment". At a press conference in Montreal today Ubisoft Montreal, the firm's biggest internal studio, announced the purchase of local VFX outfit Hybride, which works in cinema, TV and advertising.

Founded 15 years ago, Hybride employs 80 staff and has worked on Spy Kids as well as the iconic Sin City and 300. Ubisoft said it plans to work closely with the team to share technology and jointly develop tools "in order to optimise the creation of both video games and visual effects and to offer gamers visual experiences that rival those of the cinema". But at the same time Hybride will continue to work with its film partners - giving Ubisoft a big boost as the firm looks to leverage its IP in the movie industry.

Hybride's film work will be very lucrative for Ubisoft - it forecast that contracts for cinema, television and advertising jobs initially generate sales of approximately €6m to €7m and a current operating income of about 10 per cent of sales. "The future of our industry depends on our ability to create brands that captivate audiences and to extend those brands to other forms of entertainment," commented Yves Guillemot, chief executive officer at Ubisoft. "The acquisition of Hybride falls directly into the strategy that has already led us to open a digital creation studio in Montreal and to acquire the Tom Clancy brand for video games and ancillary products.The exceptional quality of the team at Hybride and the expertise of our Ubisoft teams will allow us to create one of the best 3D animation studios in the entertainment industry."

"This alliance is a true first for the industry," continued Yannis Mallat, chief executive officer of Ubisoft Montreal called the alliance 'a true first for the industry'. "Ubisoft and Hybride share the same vision of entertainment convergence and a common passion for innovation and creativity," he said. "It is the quality and innovation of our artists that made Hybride into one of the most successful studios in cinema and the most important visual effects producer on the North American East Coast," stated Pierre Raymond, founder and chief executive officer at Hybride Technologies.

My take on all this is that Ubisoft, in its continuous quest to explore artistic real-time rendering (see the new Prince Of Persia post from a few weeks ago here), has made a strategic move in this partnering which will hopefully see the boundaries of non-photorealistic rendering stretch even more...

International Animation Conference in Bournemouth

From Friday 18th to Sunday 20th July, internationally renowned speakers from the world of animation will be converging on the Arts Institute at Bournemouth to take part in the Society for Animation Studies International Animation Conference entitled ‘Animation Unlimited’.

Mobile users make same mistakes to physically-impaired computer users

As I am about to run my own user study involving mobiles, it is interesting to report on the findings of a related academic research project. Mobile phone owners make similar mistakes to physically impaired computer users when using the technology, according to new research from The University of Manchester. The first set of results from research funded by the Engineering and Physical Sciences Research Council (EPSRC) indicates that many able-bodied people make the same errors – and with similar frequencies – when typing and 'mousing' on mobile phones, as physically impaired users of desktop computers.

According to researchers in the School of Computer Science working on the RIAM (Reciprocal Interoperability between Accessible and Mobile Webs) project, mobile owners press the wrong key and press the same key repeatedly by mistake. They also found mobile users tend to click the wrong area of the screen, click the screen multiple times in error, and make mistakes when trying to drag and drop information. “These types of errors have been a big problem for physically impaired users for a long time,” said Dr Yeliz Yesilada, a senior researcher on the project. “But solutions have been developed for all of these problems in the form of small assistive computer programmes, which supplement Windows and Mac operating systems.”

For the study, researchers at Manchester re-analysed earlier work by scientists at the University of Edinburgh who had looked into the problems of physically disabled users. They then re-ran the experiments with mobile users and found that a significant correlation existed between the two user groups. “In recent years solutions have been built to help disabled users and it is hoped these solutions which can now be applied for the benefit of mobile phone users,” said fellow researcher Tianyi Chen.

“By using solutions developed for disabled users we can help handset manufacturers, such as Nokia and Sony, to reduce the time we all spend correcting errors on our mobiles. Software already developed for PC users with disabilities could automatically correct erroneous commands and help reduce those annoying times when you accidentally cancel a text message or call someone by sitting on your phone.”

The two-year RIAM project is supported by £205,000 funding from the EPSRC.

Interesting news on the future of Symbian

In a major re-organisation Nokia, Sony Ericsson, Motorola and NTT DOCOMO will unite the various flavours of Symbian - and join with remaining stakeholders AT&T, LG, Samsung, ST Microelectronics and Texas Instruments to establish the Symbian Foundation.

The aim of the foundation is to extend the appeal of the unified software platform, available for members under a royalty-free licence. To enable the Foundation, Nokia announced plans to acquire the remaining shares of Symbian that it does not already own for £209 million and then contribute the Symbian and S60 software to the Foundation., from the Foundation’s first day of operations.

The spectre of Google Android would appear to be hovering over this strategic move by Symbian, which has hitherto commanded a huge market share lead in the OS space. Symbian has shipped in over 200 million phones, across 235 models. This year already, over 20 new mobile phones have been announced. The news came on the day of Symbian’s ten year anniversary (24/06).
