Message-ID: Date: 6 Feb 91 05:51:31 GMT Sender: gleicher@OREO.GRAPHICS.CS.CMU.EDU Distribution: comp Organization: School of Computer Science, Carnegie Mellon University Lines: 24 Just a whim but. . . . . I'd like to play around a bit with some ideas about solid modelers. I was hoping to experiment a bit before I dove in and started to design one. Does anyone have some code to implement the basic functions for CSG models? I'd really like to find something that could take a CSG tree (with the most basic of primitives) and draw a picture of it (or give me a list of polygons which I could send down the graphics pipe or convert to postscript). I'd like to find a C or C++ or Lisp library, though if I could get the source code to a whole modeller that I could play around inside of, that would be great too. Failing this, I'd appreciate pointers to algorithms which would help me build the simplest possible (get it up and flying quick) displayer for CSG models. (My interest is in user interfaces and the design process, not in solid modelling algorithms, so at this early stage, I'd like to avoid the latter as much as possible) Thanks, Mike
