Hi Roger ... I didn't cut and paste this one right. The first repetition was supposed to be D5. off_util tet | off_trans -R 0,1,1.61803398874989484820,0,0,1 |...

Hi Adrian, ... For this one it looks like the sequence should be 0,0,1.618... instead of 0,1,1.618 in both occurances. I added color by symmetry into iso_delta...

Hi Roger ... It is an interesting idea, and it should be possible. The aim is to create a component colouring so the program would recreate components and then...

Hi Adrian, I noticed that 10-tetrahedra is also 5 stella octangula. Also could be though of as compound of 5 cubes with the cubes each replaced by a stella...

Hi Roger ... If the map can't be opened then init_color_map() should return 0. The program could then test for this and choose an alternative map. I think it...

Hi Adrian, ... I think you mentioned it is not wise to have shared maps in the code. But if it is done and the map is not there then it can crash. Perhaps if...

Hi Adrian, ... I messed this up a bit! It is X that should be rotated 45 degrees. Then the Stella Octangula is still formed but is in a sort of dihedral...

Hi Adrian, iso_delta is running good. I was impatient and tried to run it before the build was complete and installed. It was crashing. Then I determined that...

Hi Roger ... The map that you finally use could be an internal resource. Jumble is what I currently use when I want a map like this, but it is not perfect. ......

Hi Adrian, The good news is I think iso_delta is done with coloring logic. I also found some bugs in some of the deltahedra cases. It looks like I have case k...

Hi Roger ... That is right. Each model type can do its own thing. It is just coincidental that the current models use the same colouring. Likewise, for the...
