Viewing in 3D

Viewing in 3D. Chapter 6. The 3D viewing process is inherently more complex than is the 2D viewing process. In 2D, we simply specify a window on the 2D world and a viewport on the 2D view surface.

Projection

Projection. Our 3-D scenes are all specified in 3-D world coordinates To display these we need to generate a 2-D image --- project objects onto a picture plane Projection is just one part of the process of converting from 3-D world coordinates to a 2-D image.
