To do normal mapping in Deferred Rendering is little dificult because you need to store in G-buffer tangent and binormal if you want, but it is easy to calculate. Or you can calculate TBN matrix per pixel with your 2D … Continue reading →

Hi all! A little update of specular effect. Now with support of RGB channel. I have a screenshot with edge detect anti-aliasing: Look, blue in metal and red in crystal… painted by Prompt :roll:

I’m adjusting the params of my SSAO shaders. I’m trying to have more darkness in occlusion zones and more clean the others fragments. So adjusting selective fragments I have more performance.

Hi all! Today I’m testing new map, specular map in RGB (this is only white) with BigDady 2 model, see the crystal in the “face”: Well now, the rendering process in screenshots, read more!

Hi there! I have now Big Dady 2 model fixed. The texture coords was inverted in V coord. Now I mix my deferred lighting implementation with SSAO. I have no specular map applied yet, but I have other problem here. … Continue reading →

Hi there! Today I see an error in SSAO calc, near of the camera you can see fake occlusion. This is definitely wrong. So now is fixed: I tested different samples, I think 8 it is ok for normal GPU … Continue reading →

Hi there! The next step with my SSAO is to use more complex model, in this case BigDady2 of biosock, thanks Llorens ;) I use the SSAO result and a blur shader with one 2x downsampled. Original SSAO in fullscreen … Continue reading →

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 … Continue reading →

I forget to apply the new texture coords in Normal Maping -_- So… this is the result now: Before
