wire4

This is the initial release of the 4D wireframe viewer that I wrote for my master’s thesis, “Four-Space Visualization of 4D Objects”, in May 1991. The thesis is also available in this same GitHub project or from http://hollasch.github.io/ray4.

wire4 User Manual

See the Wire4 User Manual for usage information.

psplot

psplot is a simple PostScript plotting tool to convert wire4 output to a PostScript file. See the psplot User Manual for more information.

You will probably need to tweak the makefile to get it to run on your platform. I’ve tried to make this as straightforward as possible, but let me know if you have problems.

Wire4 supports wireframe display of arbitrary 4D objects (from ASCII input files) and displays objects with user-specified edge colors, depth-cueing, and interactive 3D and 4D rotation. Both 4D to 3D and 3D to 2D projections can be interactively set to parallel or perspective projection. Also included in the package is a program to generate simple PostScript files of arbitrary wireframe views.

Wire4 uses the GL library, so it is mostly useful for SGI boxes, although other platforms that have a GL compatibility library may also run the program.

Also available for release is my 4D raytracing program. Let me know if you are interested and I’ll send you a copy. Ray4 runs on any platform that supports C and floating point, but currently the only display programs available are for the Amiga, SGI platforms, and Sun rasterfiles.

Finally, I’d like to acknowledge and thank the folks who volunteered to beta-test this software for me:

  • Greg Aharonian
  • Brian Carney
  • Mark Ferneau
  • Marty Ryan
