Your program will support the following features:

Menus:

Selection of transformation mode and coordinate system.

Valuators:

Mouse movement will be used to specify scalar parameters.

Modelling Transformations:

Rotation, translation, and scale.

Viewing Transformations:

Camera rotation and translation, perspective.

3D Line Clipping:

To avoid divide by zero, you need to clip all lines to the near plane.
Clipping to other planes is optional.

Double Buffering:

To avoid redraw flicker.

Tcl/Tk will be used for user interface support.

OpenGL may only be used for 2D line drawing in a [-1,1]x[-1,1] NDCS.

You must implement all transformations and clipping yourselves.
