Adrian, Vladimir Bulatov (on another list) recently suggested that... Let me add my interpretation of the k-4 crystal structure: It fits inside of cube with...
Hi Steve, ... I will defer this to Adrian for the time being since his reply on K4 is pending. ... I am still looking into hcpd and haven't found anything...
Hi Steve, ... After finding other examples of hcp on the net, I am questioning your hcp model. The hcp model on your page looks like stacks of hexagonal ...
Hi, Since implimenting the 230 Space Groups is easier than I thought I am going to start working on it now. The x,y,z transformations are all given here in a...
Roger, ... am going to start working on it now. ... That's real nice. ... That sound's good too. ... That's sounds very cool...I will have to see this in...
Roger, ... am going to start working on it now. ... That's real nice. ... That sound's good too. ... That's sounds very cool...I will have to see this in...
I've started working on space_groups and I think I've ironed out most of the preliminary bugs and am ready to start importing the transformations. Formating...
Hi Roger ... I have been thinking that these sort of applications would probably be plugins for the viewer application (which I see you mentioned in a later...
Hi Steve ... This could be seen as the vertices of a packing of hexagonal prisms of two edge lengths, but it isn't HCP. I don't believe that HCP can be made a...
Hi Roger ... I remember seeing the K4 lattice posted somewhere before and I couldn't tell from the article exactly what it was. Now I have a description of the...
Hi Dick ... Here is the original http://www.freewebtown.com/adrian/misc/kc_tet_03.gif A frame can be made with a command like kcycle -t 0.05 -n 7 -a 20 |...
Hi All I haven't been able to do much on Antiprism recently. I am hoping that I can now do a little programming and will be able to continue with development,...
... That one is real nice to watch. Such a simple motion and yet it seems to be continually rotating inwards. Can't help but think it might describe something...
Hi Adrian, ... Here is the most recent iso_delta. http://www.interocitors.com/tmp/iso_delta.zip The symmetry code is still the old code so I will have to...
Hi dharmraj ... Smoke rings and bubble rings have this sort of rotation. I had a quick look for a video and found this one of a dolphin blowing bubble rings ...
Hi Roger ... The release is based on 0.17.1 with the symmetry alignments I sent you so I think your current iso_delta should be correct for 0.18. I gave it a...
... I have built the eight wheel model in Synergetics. The wheels are each on an axis that would go through the triangular faces of the VE. When each wheel...
Hi dharmraj ... I can imagine it might be difficult to set up the kaleidocycle connections in SpringDance to achieve that sort of motion. The rubber tyre...
Hi Adrian, ... I did a diff on the changes. The geom in verbose_output is not needed and could be removed. I had originally thought there could be some ...
Hi Roger ... Great, I will add it in then. The symmetry alignments are different in the current development version, so there will probably need to be changes...
Hi Adrian, While you were away Steve Waterman and I were discussing lattices. Steve's hcp mod to lat_grid was indeed hex prisms. I am not sure what your...
Hi Roger ... Originally I wrote it just to produce ball packs and grids that I wanted to view. The program worked with integer coordinates but I made another...
Hi Adrian, You might be able to run InstantReality now, though it says Ubantu 7. http://www.instantreality.org/downloads/ ... Perhaps a general space_fill...
Hi Roger ... I will have a look. Have you used it much? ... I don't think it would normally be considered a packing. Each ball is held by three balls in a...
Hi Adrian, ... I looked at the freewrl page and it looks like it has come quite a way since I last visted. It probably does everything instant reality has and...
Hi All I have just released Antiprism 0.18 http://www.antiprism.com/download This release is mainly to correct the problem of program crashes when build with...
Hi Adrian, I had no trouble building this in Cygwin. I did a Cygwin update before hand. I was able to do convex hulls. Is there anything else that I could try?...
Hi Roger ... This is what I had in mind for unitile3d. For unitile2d I just make a minimum section of tiling and repeat it by translations. This would also...
