Hello. I hope someone can help me. If in my code, I enable convolution and then blending in that sequence, is this what happens in the hardware pipeline or is blending done first and then convolution applied? Thank you.
I can’t answer directly this question as you seem to be using the imaging subset and I haven’t but I suppose that if you look at the OpenGL 1.2 specifications in PDF format (downloadable somewhere on the opengl.org site) you will find what you need. What I’m thinking off is a diagram of the OpenGL state machine which, although intimidating at first, has a wealth of information of that sort : is blending applied to glDrawPixels operation, etc… And if you learn it by heart, you can easily impress any nerd out there
