[osg-users] A problem related to the ive file size and loading speed

Hi all, I convert some existing 3ds models to ive format through the following two steps: 1) call osgDB::writeNodeFile func to save the loaded 3ds model into osg format; 2) run osgconv to convert osg to ive format. But I find that the size of ive file I finally get is much larger than the

Re: [osg-users] Shadow techniques status

Hello Jim, ShadowMap does suffer from bad aliasing when the viewpoint is very near the shadow. The Orange book (GLSL shader) describes how to super-sample the depth buffer to mitigate aliasing. Indeed, aliasing is a big problem with vanilla shadow mapping in almost all real-world cases.

John, Digging into my memories on the subject... One issue is, like you said, keeping data from paging out when the renderer is idle. One approach might be to force a cull traversal every so often, or to visit the scene graph and manually update the timestamps on your PagedLODs. There may be
