Recursive cubes.
|
||
|
|
This class represents a recursive cube tree where an element is recursively
|
||
|
|
defined as a cube with the same element at each side (only smaller).
|
||
|
|
It demonstrates the use of glPushMatrix and glPopMatrix in the
|
||
|
|
construction of recursive transformation trees.
|
||
|
|
The method "render" sets the projection and view via "setup_projection",
|
||
|
|
the scene light via "setup_light" and starts the recursion by calling
|
||
|
|
"render_recursive". This method calls itself to perform the actual
|
||
|
|
recursion. To render a single cube it uses "render_cube".
