Ecoinformatics Touchtable by VeRSI

Very informative video by the Victorian eResearch Strategic Initiative (VeRSI) on their combination of ArcGIS with their scenario plugin and the 3D game engine SIEVE for visualization; all linked to a touchtable user interface.

Plant Modeling at Siggraph 2011

Presenting my own poster “Model-based Visualization of Future Forest Landscapes” on the use of Biosphere3D in the Kimberley project at CALP, I got in touch with other researchers in the field. LIAMA, the Sino-French Lab of Computer Science, Automation and Applied Mathematics in Bejing, presented a poster on GreenLab. GreenLab is a program for the stochastic, functional and interactive modeling of plant growth that also considers different growth conditions. According to Prof. Kang, the development of GreenLab goes back to AMAP and Philippe de Reffye, one of the AMAP developers, who is also guest researcher at LIAMA and contributed to the development of GreenLab. The libraries of GreenLab will also contain more Asian species which are still rare in 3D. With its potential for functional modeling, Greenlab may become another promising plant modeler.

Later in the day, I visited the Speedtree booth. Speedtree clearly aims at Game Developers and Movie Makers; therefore it does not need to integrate botanical rules but it has to provide artistic control and “directability”. Furthermore, performance and different LODs are important for game developers and in gaming, SpeeTree is the current state-of-the-art. For landscape architects, it may be over the top with the basic version of SpeedTree Studio selling for $850 while the professional version, including a world construction set, can cost more than $12k.

Siggraph 2011 – Day 3

One of todays` highlights at SIGGRAPH 2011 in Vancouver was the approach of Prof. Deussen`s group in Konstanz and their partners at the universities in Shenzhen and Tel Aviv to use so-called “texture-lobes” for tree modelling from Lidar data.

The afternoon was dedicated to urban modeling, starting with a review of the latest literature by Peter Wonka (Arizona State University) and Daniel Aliaga (Purdue University). During the second part of the session, Pascal Mueller from Procedural/ESRI (CityEngine) presented issues encountered in practice and their new Urban Vision project together with the urban planning department of San Francisco and Urban Sim (Paul Waddell). The session closed with a visually very engaging case study by Michael Frederickson from Pixar, using CityEngine for virtual London in Cars 2.
