Shading and 3D Orbit

Shading and 3D orbit Shading and 3D orbit have been used in previous chapters without any discussion. In this chapter we will investigate both topics in greater detail.

Shading Shading allows certain models to be displayed on the screen as a more realistic coloured image. The models which can be shaded (and rendered) are 21/2D extruded models, 3D objects, 3D surface models and solid models. We will use some previously created 3D surface models to investigate the topic.
