Hi, In general osgPPU is a library/node kit for osg to render 2D quads (screen aligned or just offscreen with different sizes) with applied shaders on it. The result of the rendering is stored in a texture and can be used as input to another shader (another quad). In this way you can create a pipeline of shaders which compute something based on different inputs.
The first idea was to use it for post processing effects, where you perform some computations on camera's RTT texture. However it can also be used just for some inbetween computations similar to GPGPU. Just take a look into examples and documentations on the homepage they should help you to understand what it is usefull for and which osg soup one can cook with osgPPU as ingredient ;) Cheers, art --- forest37 <[EMAIL PROTECTED]> schrieb am Di, 21.10.2008: > Von: forest37 <[EMAIL PROTECTED]> > Betreff: [osg-users] what can we do with osgPPU? > An: [email protected] > Datum: Dienstag, 21.
