Hi Daniel and Robert, Yes, TSM was only an idea in my mind before and not implemented in the submitted code, and now it is already kicked out of my mind. :-) I'm considering TSM before because current PSM method (I think it is LiSPSM, isn't it?) has
Current implementation contains a PSSM implementation which could improve the shadow appearance a lot in large environments. VSM is also included but it seems not work even for some very simple scene (e.g. the osgshadow example works with VSM with the argument "-3", but not "-1" and "-2"). I'd like to consider fix the problem or use some better methods like ESM later. There are still something in my TODO list for VDSM: 1. Implement a usable VSM/ESM technique. 2. When setDebugDraw(true) set, create a HUD window showing each shadow map textures; and a geometry which tells the position of the light frustum. To be honest, I don't know what current debug drawing shows and how it could help debug the program. 3. Support outputting the shadow map textures and matrices to user applications, with which we could add VDSM results to customized deferred shading pipeline. Any suggestions about that?
