Geometric Transformations 2
(The tutorial solutions are also available)
- Draw a cavalier projection of a block of size x=2, y=3, z=4.
Use a 30-degree projection, i.e., the z-axis should make a
30-degree angle with the x-axis.
- Give a projection matrix that produces the cavalier projection
of question 1. Ensure that points lying the xy-plane are unaltered
by the projection.
- The gluViewport() function call is used to setup the
transformation from normalized device coordinates to the display
coordinate system, as shown below. Derive the necessary 2D
transformation.
