Hi Roger ... I like these animations too. Also, it is nice to be able to add in the transparency now as it really helps show the surface. ... It is a good...
Hi Adrian, ... I've looked at the .m files and they are there is a lot of calculations going on. Each one would have to be custom made, if not from scratch,...
Hi Roger ... It could do that, but initially I would be considering animations where it is feasible to generate the model stages as needed. This is what I did...
Hi Adrian, I have the Jitterbug app and it is cool! With edges on there seem to be an anomoly once in a while. ... I have a sequence of 20 frames which...
Hi Roger ... I don't remember seeing any here. Was it edges joined at one vertex but pointing in the opposite direction of the other vertex? ... I currently do...
Hi Adrian, ... to be ... This is hard to describe. Whenever the model passes through an octahedron, there are a couple of free edges that flash on for an ...
Hi All I have had a look at writing a program that models polyhedra with Spidron units http://www.szinhaz.hu/edan/SpidroNew/ Here are VRML models of some...
Hi Adrian, There is a current discussion on self dual polyhedra and some canonicals come into play. Do I remember correctly that canonical.exe ends up having...
Hi Roger ... The edge distances should all be 1 from the origin. The centroid won't necessarily be at the origin. ... The natural reciprocation centre for the...
Hi Roger ... What antiview does is to put a box, aligned with the coordinate axes, around the points, and use the centre of that as a default point to look at...
Hi Adrian, I was once told that the George Hart algorithm for canonicalizing can get stuck, but it wasn't explained why. I was trying to canonicalize is what I...
Hi Roger ... I messed around with various settings and added some "joggles" to the program but rarely saw the correct canonicalisation. If you use small -e...
Hi Adrian, ... Hey, if this works then good enough! After all, the reciprocal is also self dual. I tried it on the Hexagonal one (I have trouble with all...
Hi Roger ... This was one of the things I tried on the difficult one. It didn't help in this case, but maybe it would with others. You can project onto a...
Hi Adrian, ... I think "projection onto a sphere" is something different than what I was thinking! ... I forgot about the repel program! This does what I was...
Hi Roger ... Perhaps you were thinking of something more like off_util -S ! This then actually works fine with the difficult one from before, and also with the...
Hi Adrian, ... Oh I see now. It was there all along! More coffee! ... Doing it this way I don't get a "messed up" J8+4, but it doesn't canonicalize, it just...
Hi Adrian, ... That was it. I wasn't paying attention to the interation count, but it was always 1000! I have a script set up for canonicals and entered an ...
Hi Roger ... I'll add that to canonical, and to the other iterative programs. Also, I notice that the documentation for canonical says that the default for -n...
... While I was looking at it, I also fixed the misreporting of the final count in canonical and repel, which is out by one. Adrian -- Adrian Rossiter ...
... Maybe that is why I never noticed, because it wasn't a round number! Should the off_util -S idea be placed in the documention? It makes sense not to build...
Hi Roger ... It would be helpful to mention it. I have added it in. I am starting to try and tidy everything up for an Antiprism release, maybe next weekend....
Hi Adrian, ... I forgot to comment on this. I'm going to ask Martin about how he finds an all encompassing viewpoint for a scene. Once he gets back to a...
Hi Adrian, I've been behind in doing this. One thing about the examples is that without the actual off file used in the examples, some of them are hard to...
Hi Roger ... I don't think there is much in it, but it might be slightly clearer to split the command in two and name the example .m file. I will do that. ... ...
