Objectives of Viewing transformation
After going through this section, you should be capable to:
- Explain the projection;
- Classify different types of Perspective and Parallel projections;
- Expand the common transformation matrix for parallel projection;
- Explain and develop the transformation for Orthographic and oblique parallel projections;
- Expand the transformations for multi-view as front, right, top, rear, left and bottom view in the projections;
- Identify the foreshortening factor and categorize the oblique projection on the basis of foreshortening factors;
- Derive the transformations for common perspective projection;
- Illustrate and derive the projection matrix for single-point, two-point and three- point perspective transformations, and
- Illustrate the vanishing points.
