Problem 7

Write a program that displays a sphere in the
display window and allows the user to switch
between solid and wire-frame views of the sphere,
translate the sphere along any dimension, rotate
the sphere around its center in any direction, and
change the size of the sphere (i.e., its radius).

Problem 8

Write a program that displays a torus in the
display window and allows the user to switch
between solid and wire-frame views of the torus,
translate the torus along any dimension, rotate
the torus around its center in any direction, and
change the sizes of the torus’ defining properties
(i.e., the radius of its cross section ellipse and its
axial radius).

Problem 9

Write a program that displays a sphere of fixed
radius at world coordinate origin and allows the
user to adjust the number of longitude and latitude lines used to approximate the sphere’s surface as a quadrilateral mesh. The user should
also be able to switch between solid and wireframe views of the sphere. Vary the resolution of the mesh approximation and observe the
visual appearance of the sphere in both solid and
wire-frame mode.

Problem 10

Write a program that displays a cylinder of fixed
height and radius at world coordinate origin and
allows the user to adjust the number of longitude and latitude lines used to approximate
the cylinder’s surface as a quadrilateral mesh.
The user should also be able to switch between
solid and wire-frame views of the cylinder. Vary
the resolution of the mesh approximation and
observe the visual appearance of the cylinder in
both solid and wire-frame mode.
