Right now he especially needs a half-dozen more ACM members to phone and say they support forming a local group. Please tell colleagues who don't get news.

Send mail to "xpert-request@athena.mit.edu" to get on the list. ------------------------------ Date: Tue 11 Nov 86 14:05:04-PST From: Richard Steinberger Subject: request for GKS advice I'm looking for a package of graphics programs. It should include a current GKS set and a group of higher level routines that allow 2-D, 3-D, halftones, contours, and the usual other desired features such as a choice of fonts. It should run under VMS 4.4 (soon to be 4.5?), and be able to output to at least an LN03+ and the VT240's; imagen would be a plus. Cost: under $3000? Does anyone have any recommendations? Should I just get DEC's GKS and write my own higher level routines? Thanks in advance to all who answer. I'm not on the info-graphics dist. list. Could you please reply to me directly. -Ric Steinberger STEINBERGER@SRI-KL.ARPA.#INTERNET (415)859-4300 ------- ------- ------------------------------ Date: Tue, 11 Nov 86 13:17:25 est From: "Emily S.

I am trying to solve the following problem, A ^ | +--->B That is, with the two images A and B, I like to produce intermediate images between A and B. I wonder anybody has attempted to do so. Could you let me know what sort of literature I should look into especially on the perspective problem involved.

The objects consist of planar faces. For each picture of the animation, the coordinates of the endpoints of the edges are known, together with information about the movement of each endpoint. I would like to obtain references of papers, describing hidden-line algorithms which use some kind of frame-to-frame coherence, which can be applied in this situation. I only know one paper in which frame-to-frame coherence is described, but in the context of fixed objects and a moving viewpoint : H. Hubschman and S. Zucker, Frame-to-frame coherence and the hidden-surface computation: constraints for a convex world. ACM Computer Graphics, 15 (3), 1981, 45-54. Dirk Roose Dept. of Computer Science K. U.

However, I just found out that I sent it to 'request' rather than the moderator for submission. If that article is not being forward to you, then the following is the article again or else ignore this submission.
