Scale & Lights

system · March 24, 2001, 5:26am

When I make a “scale” on a 3D shape (ex a sphere) happen that light on it change drastically… Exactly when I “enlarge” it, the sphere become darker while, when I “reduce” it, the sphere become very bright… Where is my error ? What can I do ?

Use …
glEnable(GL_NORMALIZE);

or glEnable(GL_RESCALE_NORMALS) if available. Might be slightly faster then GL_NORMALIZE, depending on the OpenGL-implementation.
