I'm not shure that we've understand well. I'm trying to draw an infinite surface (using java3d) and I've tried to overwrite initSceneGraph() but I don't know how to set boundares (using BoundingBox, BoundingLeaf, or maybe something else). For example, I've set axes from -5 to 5, and I want surface to be seeable only in square which diagonal points are (-6,-6,-6) and (6,6,6). Keep in mind that I'm a real begginer (and I don't know English very weel, as you probably already realized). If you have some other suggestion please write.
Thanks!
