Hi Adrian, ... I didn't get it to compile under MSYS/mingw because it wants things I don't know how to install (even if they are available). I am beginning to...
Hi Roger ... I haven't built it but the documentation says it depends on GLib, which is part of GTK+ http://www.gtk.org/download-windows.html ... MinGW gets...
Hi Adrian, ... They just say it is preferable to build with Cygwin. The configure doesn't try -mno-cygwin so it is using the cygwin library. As an aside, mingw...
Hi Adrian, I've been pulling my hair out on the following problem. The Triclinic case is the most variable allowing x, y and z vectors be any scale and alpha,...
Hi Roger ... Say the transformation is X=(1, 0, 0) -> x=(1, 0, 0) Y=(0, 1, 0) -> y=(y0, y1, 0) making angle 'a' with x Z=(0, 0, 1) -> z=(z0, z1, z2) making...
... The last message needs to be viewed with a fixed width font http://tech.groups.yahoo.com/group/antiprism/message/1668?var=0&l=1 But the formatting is still...
... It is actually behaving almost correctly (the colours are attached to the numbers and the renumbering makes them incorrect), but not very intuitively. The...
... On further investigation the colouring is fine. So, the only change needed is to preserve vertex order in conv_hull when not using -a. Adrian. -- Adrian...
Hi Roger ... That doesn't sound so good then. If it is reasonable to output the coordinates at a higher precision then gts2oogl could be amended to do that (I...
Hi Adrian, ... This is an interesting find and rather timely. The other day I was peeling an onion. What may this have to do with convex hulls you wonder? I...
Hi Adrian, ... I placed higher precision numbers in a file and it still gave me 5 or 6 places. I am concerned that the internal precision is less than desired,...
Hi, I thought I had better make a list of programming projects I have mentioned in the past. There may be some I have forgotten as well. bravais - in...
Hi Roger ... There might be some interesting properties to discover relating the points and the hulls. ... The different Waterman polyhedra share some vertices...
Hi Roger ... With %g the precision specifies the number of significant digits. ... It might be an idea to ask about the expected precision of the coordinates...
Hi Roger ... The matrix pre-multiplies the vectors, and so the vectors are column vectors. When the x, y, and z vectors are written into the transformation...
Hi Adrian, ... I works good. There are conditions such that the paralleliped goes flat. With all edges at 1, angles of 10,20,30 will be flat. If I make it...
Hi Adrian, ... Well, Steve also wanted to be able to get the convex hulls by excluding vertices based on radius. One way would be to find all the unique radii ...
Hi, I remember another one. When a polyhedron is triangularlized it creates adjacent coplanar triangles. If the GTS system can be used to make slices, it would...
Hi All I have released Antiprism 0.18.1 http://www.antiprism.com/download This release is to correct the problem of program crashes when built with recent...
Hi Roger ... I was surprised that you had results for 9,20,30 as this is unattainable and so I thought the calculation would fail (it can only fail on the...
Hi Adrian, ... Only the first angle survives. If I tried 20 or 30 in the first position that also survives but the other two are altered. ... I will test the...
Hi Roger ... This is because the construction of the first angle can't fail, the Y vector can be rotated to any angle in the xy-plane, and it is independant of...
Hi Adrian, I remember someone asking if the dual of K4 (name now in dispute) had been done and what it is. I looked up duals of lattices and the subject seems...
Hi Adrian, I am coming down the home stretch on the bravais program. If you'd like to see what I have so far, I can send it to you, but it isn't ready for...
