I was wondering what the destination of data copied with glCopyTexSubImage2D is… is it the texture bound to the specified target (e.g. GL_TEXTURE_2D) for the currently active texture unit only?
Or does it write to multiple textures if i have multiple textures bound to TEXTURE_2D targets on multiple units?
If anyone could point me to the right part of the spec … i don’t find it
Is there something like “the (single) texture object”? I thought a texture object is simply the collective state information belonging each texture?
If you are sure that only the texture bound to the currently ACTIVE unit is affected, thats also what i would have guessed - however, could you point out to me where i can find it in the spec?
I just want to know because i didn’t fint anything …
