Today I begin my SSAO based in many website, papers and forums. This first approach has around 2ms of cost. But if the camera is near to objects app performance down drastically. By the way it’s ok for first day of coding.
I need to do 2 things, render in less resolution and to do a vertical and horizontal blur, then mix with specular and color. I believe the effect is really good now processing only, ALBEDO, NORMAL and DEPTH (in clip space).
If I complete this version soon I will relax and play a few poker hands next week. I hope this weekend to be finished the first version of ModelViewer lite version without GUI, supporting, color map + alpha pixel discard, normal map, specular map, height map for parallax mapping and deferred rendering architecture.
