Hi Roger ... As there is a problem with coding the full colour into a (signed) int, and large index numbers aren't nice to use with other maps, it might be an...
Hi Roger ... That didn't read quite right. I am making a snapshot anyway (now that the poly_kscope problem is fixed.) The value to index function is short so I...
Hi Roger ... I meant to comment on this. I think that splitting the colouring classes by element has complicated the code without bringing any benefits. I plan...
Hi Adrian, ... I didn't mean to be confusing about values to map indexes and vice versa. Except that the subject ended up going both ways! I was concerned...
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...
Hi Adrian, ... I can experiment in conway. I will try to add color by consituent and color by "sym_repeat". I tried using the rand map but jumble looks better....
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 ... 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 Roger ... I have added the handling of indexes in. The policy is that if there are any colour values for the adjacent elements then the average of the...
Hi Roger ... The Antiprism colouring code could easily be at fault. I noticed the other day that stderr in Cygwin appeared to be buffered. I had to add...
Hi Adrian, ... http://www.interocitors.com/tmp/iso_delta.zip I decided to upload it now, as I think that the new build may benefit it! A few statements at the...
Hi Roger ... Your message came through just before I started off the Windows build for the snapshot binaries, so I added the latest iso_delta in. I ran some...
Hi All Here is a snapshot of the current development code Source only (2Mb) http://www.antiprism.com/misc/antiprism-0.20.pre07.tar.gz Windows binaries and...
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 Adrian, ... I should have mentioned that one of the reasons I was at first thinking it was a new class is that ... off_util tet | off_trans -R 0,45,0 |...
Hi Roger ... I will look at making a suitable map for this. ... Instead of adding this into the library I changed the "face_color" colouring functions to work...
Hi Roger ... I thought I would check the symmetry orbit colouring on this. On first view it looked like it had failed as you can only see one kind of face from...
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, ... 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 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 All off2vrml is crashing in Antiprism 0.20.pre07 The temporary fix is replace the code at base/disp_poly around line 275 with const vector<vec3d> &vs =...
... I have switched to this, it looks like a reasonable spread over the first 60 entries http://www.antiprism.com/misc/col_spread2.jpg Adrian. -- Adrian...
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 ... 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 Roger ... I use unitile2d, e.g. unitile2d -l 10 -w 10 | off_trans -R 0,0,-90 | off_color -f U -m hsv100_0:1 | antiview -x ev Adrian. -- Adrian Rossiter ...
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 ... 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 |...
