[osg-users] Render to (part of) texture

Hi, I want to update data stored in textures using FBOs. My problem is that my textures are large and thus takes too long to update. Since only small parts of the textures need to be updated between each frame, I want to just update these parts. I believe this can be done by rendering into a

Re: [osg-users] Render to (part of) texture

If you bind the FBO to a texture you should be able to render to this texture. You can then render to a quad that covers only the pixels you need to change. But then of course, you'd have to get the source data from somehwere (possibly another texture). Maybe you can even compute the data on the
