Hi,
I had a look at the prerender example. When I started the example (using
the framebuffer) with
./osgprerender --fb --image dumptruck.osg
everything is fine. But when I use a framebuffer object, like this,
./osgprerender --fbo --image dumptruck.osg
the image has some artifacts, and I don't why? It seems, that the image
has only 256 colors. Has someone an idea? In our research group, we use
ATI graphics cards. Could it be, that NVidia cards has no such problems?
Here are some screenshots with and without the artifacts.
