An important aspect of visualization is the use of color and lightning for 3D Effects. That's why GRAPE offers the user this feature with up to nine light sources. The number of different colours and available lightsources depends on the graphics environment. GRAPE supports direction and position lightsources. There is no shadow, so inner parts of surfaces wont't be dark, the best way to see holes is to put a position lightsource inside of the object.
