Greetings,
My understanding is that most OpenGL implementations will not load a texture into VRAM
until the time that it is first used. I was wondering, will a call to glBindTexture
suffice for "using" a texture? If so, could I write a node visitor that just
visits every StateSet in my graph, pulls out the texture objects, and calls
Texture::TextureObject::bind()?
I'm trying to think of a way to preload all of my textures into VRAM so that I
don't get a frame rate stutter the first time one object or another comes into
view.
Hi, Frank,
I'm not positive, but the osgUtil::GLObjectsVisitor may already do what
you need (look at the COMPILE_STATE_ATTRIBUTES mode).
