the Impossible Cage, an Escher like scene.
Marcelo F. Vianna
1997
History 01-Nov-2000: Allocation checks
01-Jan-1998: Mode separated from escher and renamed
08-Jun-1997: New scene implemented: Impossible Cage based in a M.C.
Escher's painting with the same name (quite similar). The
first GL mode to use texture mapping.
The Impossible Cage scene doesn't use DEPTH BUFFER, the
wood planks are drawn consistently using GL_CULL_FACE, and
the painter's algorithm is used to sort the planks.
Marcelo F. Vianna.
07-Jun-1997: Speed ups in Moebius Strip using GL_CULL_FACE.
Marcelo F. Vianna.
03-Jun-1997: Initial Release (Only one scene: Moebius Strip )
The Moebius Strip scene was inspirated in a M.C. Escher's
painting named Moebius Strip II in wich ants walk across a
Moebius Strip path, sometimes meeting each other and sometimes
being in opposite faces (note that the moebius strip has
only one face and one edge).
Marcelo F. Vianna.
