Need a 3d shape class

[d00ape]

I’m working on a project using VRML to show 3d shapes of all kinds. I now search a class (or tips of how to create one) to represent an arbitary shape. For e.g. se this pic:

One shape could for e.g. be a wall (a regular box). Later the wall could have a window.
Perfect would be if I in some way could create one box and later subtract one or many smaller shapes (the windows and doors) whenever I want.

For creating the VRML it then would be good to retrieve the outside areas of the shape (the connection of all corners).

All tips are welcomed.

I think for 3d shapes better is to use OpenGL. f you would use 3d chapes in web pages, better is to use MacromediaFlash or ShockWave.
