Howdy!
I am trying to use FBOs with GetTexture method and have found
ugliness. It may very well be an incorrect use but I need to
understand how to make it all work in FxPlug!
Example Project Synopsis: Retrieve arbitrary frame from source
layer. Render source layer to view, call
glBindFramebufferEXT( GL_FRAMEBUFFER_EXT, 0 ) and clear view with
arbitrary color. Why? Because the other noid has real FBOs. 9-)
This was as clear cut as me thinks me could make the problem. If the
bind framebuffer call is commented out, it all works. Why? Is it
changing the context state somehow? Is it a masking issue of some sort?
Update.: it does not need to use the GetTexture method to die. I
came about this assumption through lack of thought. Still, why would
binding the window frame buffer cause further render calls to be
evaluated incorrectly or dismissed?
