Exercise 1: Shapes and GluLookAt()

 

Part a

 

Use the examples in Appendix C (Shapes) to accomplish the following - in separate programs - we will put them together later

 

A red solid cube, a green wire cone, and a blue wire teapot. Draw the solid cube and wire cone vertical as in the examples. Draw the teapot rotated to the right 90 degrees.

Use the default view for each - looking down or toward the negative z axis.

 

Part b

 

The text refers to stacks and slices. Define these terms by using the wire cone as an example.

 

Part c

 

Same as part a except provide the view as seen looking from above (down or toward the negative y axis)

 

 

Exercise 2: Projection Transformations - gluPerspective(), and glOrtho()

 

Draw a red solid teapot at the origin with a green solid teapot behind it (along z axis) and a blue teapot behind the green teapot (on z axis)

Provide viewings using the 3 techniques covered: glFrustrum, glPerspective, and glOrtho.

Place the viewing position at the default position.
