Hi Simon, First, I would just like to say "thank you" for posting the original OBJ files. It was very generous of you and your group. Plus, I've always be fascinated by procedural city generation.
Currently, we are working on a new framework for our various immersive displays (CAVE, Geowall, etc.) and needed models to test OpenSG's features. We had quite a few that we could use for texturing, physics, shaders, etc. but lacked a nice large cityscape that was high in number of polygons but also visually interesting. The main reason for this model was to really stress the OpenSG culling system to see what's possible. Once the framework is complete we'll be using it support the visualization and research needs of various schools and colleges here at the University. Thanks again E. --- Eric Maslowski Research Computer Specialist University of Michigan 3D Lab Autodesk 3D Studio Max Certified Trainer email: [EMAIL PROTECTED] office: 734-615-9699 mobile: 734-730-9904 -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Simon Haegler Sent: Wednesday, June 27, 2007 10:02 To: [email protected] Subject: Re: [Opensg-users] SplitGraphOp and Bounding Volumes hi eric >> Background: >> >> I have several large models from Pascall Mueller's site >> > (http://www.vision.ee.ethz.ch/~pmueller/wiki/CityEngine/DownloadModelsPompei > i). >> I would like to break up these models using SplitGraphOp to make use of >> frustum and occlusion culling. when I run SplitGraphOp on them, the >> number of occlusion tests never go above 1, and the number of nodes >> drawn is a little higher (7nodes vs. 28nodes).
