   unipoly cube | off2m > cube.m
Use LiveGraphics3D colouring
   unipoly cube | off2m -l > cube.m
Make a thickened red cube frame with blue vertices
   unipoly cube | off2m -X ve -e 0.01 -E 1.0,0.0,0.0 -V 0.0,0.0,1.0 > cube.m

Notes

off2m was written by Roger Kaufman.

Roger has made an example LG3D page and also prepared a off2m testing package which can be downloaded and used to view the off2m output.

LiveGraphics3D is free for non-commercial use and can be downloaded from the LiveGraphics3D Site.
