UNION - SUBSTRACT - INTERSECTION
I'm looking for a way to draw holes on a form. Boolean Operators is,I think, a convinient way to think the forms. FormA(SUBSTRACT)FormB would give a hole inside a form.
I don't know how it's handled with PostScript, but it should be usefull for 2D as for 3D.
A cube could be drawn by a set of face but it won't represent the features of a cube. With the actual 3DSoftware, you'll find some 3D operations working Boundary-Representation (Polygons). The Algorithms are so complex and lead often to errors (as you could see in 3DStudioMax).
One way to skip the problem is to use a solid model, it could be a CSG or other solidEngine. I've done projects by sending AutoLisp command to construct a 3D model, but I didn't found any other openSolidModelerEngine (in the way of jSound) to implement in JAVA. It should avaible soon, or maybe you know something good? Could it be great to have a solidEngine for 3D inside P5?
Maybe you know a good way to work with boolean operator inside JAVA?
