Hi - I'm building some basic geometries that I want to color up, and having read up, it struck me that the IndexedGeometryArray classes would be by far the most efficient, as they're stingy with vertices. I looked in the utils.../ColorCube.java file and find that he uses a QuadArray, which means that he declares 24 vertices and 24 triple-float colors... I can build something identical with 6 colors, 8 points, and a couple of index arrays. Is there any documentation as to which is the smart way to go? [those who think they detect a faint echo of the previous poster's reactions to some of the code in utils are not entirely wrong]. -Tim =========================================================================== To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff JAVA3D-INTEREST".
