I have a textured quad that I am using to display a float texture from
a RTT camera setup. Actually, I am attaching 4 textures to the FBO
and rendering "stuff" to each of the 4. I want to be able to hit a
key and cycle through the textures being displayed. How do I do this?
Would it be as simple as using a key handler to set a uniform
setting the texture unit in the frag shader? Also, I found that if I
enable more than 2 textures, as follows, I get a memory corrpution
error... Do I need to explicitly enable multitexturing?
geom->getOrCreateStateSet()->setTextureAttributeAndModes(0, Texture0,
osg::StateAttribute::ON);
geom->getOrCreateStateSet()->setTextureAttributeAndModes(1, Texture1,
osg::StateAttribute::ON);
geom->getOrCreateStateSet()->setTextureAttributeAndModes(2, Texture2,
osg::StateAttribute::ON);
geom->getOrCreateStateSet()->setTextureAttributeAndModes(3, Texture3,
osg::StateAttribute::ON);
