What is particularly interesting with this is that this tutorial/making of focuses on a single-building project thus highlighting a lot of the smaller, finer details sometimes lost in similar project overviews that cover whole scenes... Well worth a look if you decide to model a building of any era or style in a manual way!
The tutorial can be found at:
The roots, trunk and limbs of each tree have been meticulously modeled and textured with multiple maps. The twigs and leaves are planar objects mapped with alpha textures and bump maps, with additional maps for diffusion, specularity and sub-surface scattering (translucency). The result is up to nine texture maps per tree. The multiple mapping results in photorealistic effects previously only available in high polygon count trees that are 30 times the size and 10 times the price per tree. Plenty of landscaping and full, natural trees are available.
“Since 3D trees were first created, there has always been a tradeoff between high and low poly trees,“ said company president and art director Tom Marlin. “You either got low quality with a high quantity of trees, or high quality only with a just a few trees. Now the paradigm shifts with TreeFarm models, offering photorealism with low poly trees”. TreeFarm Deciduous Trees offers 1450 pretextured tree models, consisting of 58 tree objects, with five distinct leaf types and five colors per leaf. With seven optional bark textures and a bonus leaf texture, the total number of combinations could exceed 10,000 different looking trees. A comprehensive browser-based index, including animations and thumbnails, is available with each library.
TreeFarm Palm Trees offers 90 pretextured tree models, consisting of 18 different palm tree objects and five colors per palm frond. The average palm tree model contains 1600 polygons and palm frond maps are also 1024×1024 pixels. Mixing and matching palm fronds and barks result in hundreds of different looks for the palm trees. TreeFarm Deciduous Trees sells for a special introductory price of $299 USD plus s/h, while TreeFarm Palm Trees sells at the introductory price of $239.

The title of the publication I am presenting is "Towards Rapid Generation And Visualisation Of Large 3D Urban Landscapes for Mobile Device Navigation" and is quite fitting with the overall theme of the workshop which focuses mostly on key research issues in modeling large-scale immersive urban environments. For more information check the link below, I will of course post a full report on the workshop when I return from it, so check this space for an upcoming post on this!
