Geomview For Windows?
[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]
Hi! I've written a utility that will take a .quad file intended for use with geomview (nee Minneview), and add normals to the vertices for smooth shading. The polygons may be in random sequence; the program will find the common vertices and average the appropriate polygons. The program features what I call "edge preservation": if two polygons are sufficiently non-flat, then they are not averaged together at a common vertex. Thus the tip of a cone will can be left unsmoothed, while the vertices at its base are smoothed. You turn on edge preservation with the -e switch, which takes the smallest acceptable dot product between a pair of polygons as an argument. The smoothing code is a general-purpose package; the program is a fairly short client. It only takes ASCII files, but it would be be pretty easy to extend to binary. If any of this would be useful to you, I'd be happy to send you the source for the package, the quad format client, or both. -Andrew (Andrew Glassner / glassner at parc.xerox.com)
