Information science student in Italy, still to graduate.

I studied and know well C and Objective-C for Mac OS X and iOS (also some C++, Java, PHP and SQL). I had fun mostly with OpenGL, SQLite and Cocos2D.

I like Programming because it's like building castles with LEGO.

Feb 7	comment	Cook Torrance model implementation : black specular light I think that the c++ code was wrong, if I switch to another project I don't have this problem.
Feb 7	accepted	Cook Torrance model implementation : black specular light
Feb 6	comment	Cook Torrance model implementation : black specular light I'm studying it (also) from here: content.gpwiki.org/index.php/D3DBook:(Lighting)_Cook-Torrance , where in the last image it shows what should be the result with F0=3.0 .
Feb 6	comment	Cook Torrance model implementation : black specular light Fresnel is the term that makes this happen, if F is greater than 1.0 ,because Rough and Geom don't depend on F.
Feb 5	comment	Cook Torrance model implementation : black specular light Ok I thought it was solved, but it still doesn't work. Or better: it works only if F isn't greater than 1.0 ; Otherwise I see all the reflected light as black.

Feb 4	comment	Phong lighting model unrealistic result Sorry that I told you I was accepting this answer, but later I discovered there were more problems with the code.

Feb 3	comment	Phong lighting model unrealistic result I did an extra normalization when calculating the normal, I changed it to normal= gl_NormalMatrix * gl_Normal; Now there isn't that shadow but I still have the doubt that it's not correct. Now it looks like the last image.
