I am rendering a lot of detailed textured buildings in a dense urban scene. Most of the time, it looks great. There is a low LOD with just colored building faces, and when you get closer to a building the textured faces switch in.
But occasionally a condition arises where, when you zoom in close, one building (or a group of buildings) turns white, which seems to imply that the textured model switched in as expected, but the textures didn't get applied? This morning the application had been left running and rendering overnight, and when we looked at it about a third of the buildings (a hundred or so) were white - without textures! When the machine was rebooted (a new HP workstation, a few GB of memory, and a new NVidia graphics card with either 768MB or 1GB of texture memory), everything began to render fine again. Has anyone experienced similar symptoms? Could this be a memory leak, or something building up in the texture memory manager in an OpenGL driver, etc.?? Any insight anyone can offer would be appreciated... Bob. -- Robert E. Balfour, Ph.D. Exec.
