Hello Juan, I am pleased to say that the ping pong version works very good. Really! It is fast (on a plane with a 1024x1024 texture I have around 4300 FPS) and it looks well. So, this is a complete success. I think that is all what I need. However, I will try the EXT_shader_image_load_store version, because I want to help you to integrate this in OSG and I want to evaluate this (compare ping pong and the extension).
