I am trying to modify the "bump mapping of a torus" code by "The CG Tutorial" to change the torus to a cylinder. The bump mapped cylinder appears to be good, but in some areas (mostly the darker ones) there are strange brights that change when the eyeview changes. I do not know what I am doing wrong. The problem desappears when I do not add the specular light. Could somebody give me a clue? Here is the tutorial with the original source code: Cg Bump Tutorial Here is my modified C source code: C code Here is my modified CG vertex program: vertex program Here is the fragment program (I have not touched it): fragment program Major changes are: - I have changed the torus parametric equations and rotation matrix with cylinder ones in the vertex program. - I have added some keys to move the eyeview: a,b,q,w,+,- Thank you and sorry for my English.
