- I'm working on a program whose primary output is a set of points
- that define B-Spline/NURBS curves and surfaces.
-
- Is there any standard file format that may be better to use than
- simply dumping the control points/knot vectors etc.?
-
- The uses for the file will/might be:
-
- 1. Obviously, to be read back in to my program
- 2. to be read by commercial CAD/CAM packages (AutoCAD etc).
- 3. to be read by ray-tracers (SunVision-Geometry, POV etc.)
- 4. use a filter to convert data to PostScript for printing
-
- The file formats I was thinking of include: CGM, IGES etc. Anyone
- have experiences writing those files? (C code for generators/interpreters
- appreciated!)
-
- Thanks
-
- Himanshu
