There is a 3D grapher library called "Jun". It works on VW2.0 and distributed under the terms of GPL. Though the latest version is still 0.04, I think it's worth trying. Please check out from: ftp://ftp.sra.co.jp/pub/lang/smalltalk/jun It also contains Hypercard-like documentation system, and the description of "Jun" is written with it. But, in Japanese. Example codes may help a little for those who cannot read Japanese. It is developed by AOKI Atsushi, who is famous for the development of another class library "Mei", which contains (2D)grapher, drawtool, lisp/prolog, etc. Generally speaking, a great problem of 3D grapher is selecting and locating an object with 2D display and 2D mouse space... Even if the grapher model contains objects in 3D space completely, the view may map them into 2D space, and the controller must struggle remapping them to 3D space. We should need more sophisticated device than Display/Mouse, for 3D hadling. -- WATANABE Katsuhiro Software Research Associates, Inc. (Tokyo JAPAN)
