I have loaded an object, and when I draw the object, I set the color to green.. After drawing the object, I draw lines in red.
It all worked out fine. The problem arise when I input lighting properties. When I create a light source, everything where the light projects becomes white. Why does the lighting over writes my color? And how do I solve this problem?
提前感谢。
你们的法典将有助于诊断问题。 这种说法与为这些物品设置材料的问题一样(这界定了它们如何与灯光进行互动)。
请参看glColorMaterial。 The following snippet of Code will set up:
GLfloat mat_specular[] = {0.3, 0.3, 0.3, 1.0};
GLfloat mat_shininess[] = { 10.0 };
glMaterialfv(GL_FRONT, GL_SPECULAR, mat_specular);
glMaterialfv(GL_FRONT, GL_SHININESS, mat_shininess);
glColorMaterial(GL_FRONT_AND_BACK, GL_AMBIENT_AND_DIFFUSE);
glEnable(GL_COLOR_MATERIAL);
