  1. OPENGL lesson 3

    the problem has been solved. in order to specify color at each vertex, glEnable(GL_COLOR_MATERIAL) must be called. and if no light is specified, GL uses the default lighting, that's why in NEHE's lesson3 the colors can be shown without calling lighting functions.
  2. OPENGL lesson 3

    i have just started learning OPENGL, i use MASM for programming. in lesson 3, if there isn't a lightsource in the scene, how can the color be shown? and i tried to put up a scene with a lightsource and a triangle, the glColor3x (b or f) function doesn't change the color of the triangle , it always appear gray, i don't know why.
