Hi Roger ... It would probably be better that Antiprism worked consistently with homogenous coordinates. They allow points at infinity to be represented, which...
Hi Adrian, ... What I was refering to might be different. It is hard to find much information on raw GKS (Graphics Kernel System) because so many higher...
Hi Roger ... The matrix rows look like (1,0,0,0), (0,1,0,0), (0,0,0,1/d), (0,0,0,1) so multiplying a column vector (x,y,z,1) (if that is how the matrix is...
Hi All Here is a snapshot of the current development code Source only (2Mb) http://www.antiprism.com/misc/antiprism-0.20.pre06.tar.gz Windows binaries and...
... That's not right! The display and the symmetry are misaligned by PI/2n for Dnh with n odd. The alignment is fine for Dnh with n even poly_kscope -t -s D6h...
... This was the problem. base/symmetry.cc line 642 should be sym_ax.set_perp(mat3d::rot(axis, M_PI/2+M_PI/nfold)*(*vi)); Adrian. -- Adrian Rossiter ...
Hi Adrian, ... I made this change before compiling in cygwin/mingw. I only worked on it for a few minutes but this is what I found. antiview didn't build I...
Hi Roger ... I don't know about this one (assuming there was an 'l' and it was -lglu32). I wonder if there was an earlier error. ... It is probably that the...
Hi Adrian, ... I reran the compile with scripting and found the full text: *** Warning: linker path does not have real file for library -lglu32. *** I have the...
Hi Roger ... I am not sure about this at the moment. When I make the next snapshot I will try building it in cygwin with -mno-cygwin. ... I forgot that might...
... These are the translationsi for uniform polyhedra. They mean that a small stellated dodecahedron can be made with 'u_sm_st_dod', which is easy to remember ...
Hi Adrian, ... Looking at the code I see now that the johnson polyhedra code is in the base directory. As long as there is another way to list them then the...
Hi Adrian, ... I went back and did the examples in the opening note of this thread. These look really good! I like the symmetry graphics and the base/dual...
Hi Adrian, ... This seems easier. ... Then they wouldn't need to exist in altnames.txt? I tried knocking out tetrahedron and it then does not pick it up....
Hi Roger ... Unipoly is only a thin wrapper of kaleido, but it uses the Antiprism library for convenience utilities for the command-line options, for OFF...
Hi Adrian, ... I was experimenting doing this with off2vrml which worked and is a nice model. Then I was going to try to make the cube transparent with...
Hi Roger ... I can see this too with the MinGW binaries I made. I use a little stdarg utility routine to set up the arrow model, so that was my first thought....
Hi Roger ... I can't see a reason to leave them in alt_names.txt so I plan to remove them. The internal resources are always checked last so it is possible to...
Hi Roger ... The old HSVA options were used in two different ways in the previous off_color. They were used to set ranges when constructing colour maps, and...
Hi Adrian, ... Due to number of threads I reply in just this one. I was able to do what I wanted with bravais bravais sc -g 1,1,1 -C c -F red,c,128 | antiview...
Hi Adrian, I found where poly_kscope was failing. I put a statement fprintf(stderr,"before if(v_code[v_next] < 0) in find_path v_next = %d\n", v_next); When...
Hi Adrian, ... I was looking for common elements in the uniform names. The main problem with it is when rhombi is next to icosi, they use a common i between...
Hi Roger ... I have added it back in (and changed the help!). There is now an -r option (for range) that maps colour values into HSVA ranges. The argument...
Hi Roger ... Thanks for tracking this down. The failure is when finding the symmetry of an arrow positioned by poly_kscope before repeating it symmetrically. I...
Hi Roger ... If a name matches the beginning of a polyhedron then the first match is returned. That helps as a non-specific abbreviation, but the expected...
Hi Adrian, ... This look interesting. I also think it would be easier to work with than the map creation. But I am wondering how it would look for the rainbow...
Hi Roger ... It works the same way. You can currently set the alpha value on the map like this off_color -f G -m hsv256_0:1:0_0.9_0.9_0.7 If I change to...
Hi Roger ... I tried a practice system, and it was solved. The basic equations for j89, the hebesphenomegacorona, as coordinate distances are e^2+(g-f)^2=4, ...
