Hi All I have started sorting out the edge handling as mentioned here http://tech.groups.yahoo.com/group/antiprism/message/617 The core changes are done. It is...
... I have decided to consider any edges without a colour (which are also those having colour index 0) as implicit edges. This means that -x E isn't really...
Hi Adrian, In general, I think we will all need examples of what Antiprism does with edges. ... But if I create an edge only cube, isn't that 12 explicit...
Hi Roger ... I'll give some examples and try to document it too. ... In antiview and the off2* programs the explicit edges are added first, with any colour...
Hi Adrian, It usually isn't needed, but a flow diagram might be good documentation here. The terms implicit edges, explicit edges, and digon faces all seem to ...
Hi, After looking a truncating a Truncated Octahedron into a Truncated Tetrahedron, the Trunc Tet that is produced isn't regular. The hexagons are what are not...
Hi Roger ... I haven't seen one of those before, it looks interesting. I can see roughly what is happening with the strips but I am not so sure about the...
Hi Roger ... I have just about finished the code changes, and I have written up the edge use. I haven't included a diagram, but if you read the notes and think...
Hi All Here are snapshots of the current code. They include the core changes to edge handling, the new sph_saff program, and changes to geodesic Source (500k) ...
Hi Adrian, ... When I enter this I get no edges in the m file. (-X ef is the default but added for clarity). In version 14 it did put the edges in. off2m -X ef...
Hi Adrian, ... I have antiview set up from the file manager so I always exit by the close control. Goodness, I hope that I don't have orphan antiviews! I don't...
Hi Roger ... It does look like the same bug. I fixed the -E problem last night and running the command above I get edges in the output so it appears to have...
Hi Roger ... The problem also seems to exist in the Cygwin GLUT library. I normally build the Windows binaries against OpenGLUT, which doesn't have the...
Hi Adrian, I tried running antiview from withing an MSYS shell and it will exit cleanly with the Close control. I'm not sure why this works! I did nothing...
Hi Adrian, I don't know if this is a problem but I thought worth mentioning. In either antiview (14 or 15) if I look at the first octahedron, there are no...
... Here is the source (no Windows binaries) with the -E bug fixed http://www.antiprism.com/misc/antiprism-0.15.pre09.tar.gz It includes a new program...
Hi Adrian, It appears that canonical put in the 2 vertex OFF faces in the result. The last version didn't do this of course. Which way is the correct way? Also...
It should also be mentioned that if I put the canonical output through pol_recip then that result doesn't have the explicit edges. It also maintains the edge...
Hi Roger ... It is the other way round for me here. The first one has its edges drawn like normal. The second one has coincident vertices and the edges are...
Hi Roger ... It doesn't vary with the shell here. I get the problem from Cygwin, MSYS and a DOS box. What does vary between Cygwin and MSYS though is the...
Hi Roger ... This is an error. The canonical program shouldn't change the colour of the edges. It should output the two-vertex faces that were present in the...
Hi Roger ... pol_recip doesn't currently preserve any element colours, but I will be adding this in as it would be a nice feature. (I only thought to do it a...
Hi Adrian, ... I had it backwards. The one with the coinicident vertices have minimum thickness, while the one with just 8 faces has the cylinders sized like...
Hi Roger ... When I make the next snapshot I will change canonical to initially centre the polyhedron on its centroid and project onto a unit sphere (and add...
Hi Roger ... I base the default edge thickness on the minimum distance between any two vertices. I could perhaps discount very small distances (relative to the...
Hi Adrian, ... alone ... to "version". ... This would be pretty easy. The help functions could include a call to a central printf somewhere. Then you'd only...
