... Another related issue which is best dealt with now is to allow the display method of a geometry object to be configurable. There are currently two display...
Hi Adrian, ... I've gotten busy doing all sorts of things I've been putting off. So my summer is going to good use. The bravais code is still in "almost...
Hi Roger ... I thought about these too. I have also seen them on the Javaview demonstration applet on the home page ( http://www.javaview.de is currently...
Hi Adrian, ... Their site is up today. I downloaded the latest beta as I am running an older one. ... Actually a program "off_normals" could be an educational...
Hi Adrian, I started a new thread on this. What I found doesn't make any sense so I'm at a loss. I put a printf before the fopen for alt_names.txt such as the ...
Hi Roger ... I meant to comment before, but the SWIG setup that I use to create the Antiprism Python module will also export to Java. Perhaps it wouldn't be...
Hi Roger ... Very strange. I imagine that if you can cat the file then the permissions are fine. In fopen_file() (earlier in utils.cc) the path is run through ...
Hi Roger ... It works fine here, 'off_util cube' prints the cube. The only other things I can think of is checking that Cygwin is up-to-date and trying a clean...
Hi Adrian, ... I determined what it was doing was to start from the root directory instead of /usr. If I put alt_name.txt in the C:/ directory and then hard...
... Also, it is more obvious that this is a bad fix since it only works for the Cygwin build. I still haven't determined what the actual "path rules" are for...
Here is a page noting there is a difference. I should have mentioned I'm compiling with -mno-cygwin. And by doing this it is using the mingw compiler within...
Hi Roger ... It does sound strange. Did you build Antiprism with -mno-cygwin? I wonder that would affect it. I didn't use the option when I tested here...
Hi Roger ... That sounds like it then. The programs are normal Windows programs so Cygwin assumes that the paths are relative to the root on C drive and...
Hi Adrian, ... This was a good idea and I quickly tried it, with the utils.cc code back to original state. Unfortunately this doesn't work either! I think it...
Hi Roger ... The environment variable is ANTIPRISM_DATA. If you set that as above it will hopefully work. ... I think probably the best thing is if only MSYS...
Hi Adrian, ... There are some interesting potential directions for Antiprism. I just noticed on the javaview page they have the plugin running. Using shift-z...
Hi Roger ... That is the thing. Developing Antiprism itself on MSYS or Cygwin isn't a lot of fun as the build takes so long. But there does need to be a way to...
Hi Roger ... If I remember this option made things very jerky and slow and fairly unusable on my old 233MHz computer. I have just tried U75 on my modern...
Hi Adrian, Do you have an updated routine for get_voronoi_cells? As it is, the function puts all vertices and faces into one geom. To exclude cells outside the...
Hi Adrian, ... a ... Oh it just uses the special call of centroid. It was in canonical. vec3d f_cent = centroid(verts, faces[f]); The following is how you...
Hi Roger ... Q can be any point on the face plane, so verts[faces[f][0]] would be fine. n is a normal pointing outwards from the face. The '.n' means the dot...
Hi Adrian, ... If this is true then it is more optimal and faster to do it this way. But consider this. Suppose we pass 4 vertices to it, then the convex hull...
Hi Roger ... The operation is like creating a right angle triangle PQR, where R is the nearest point on the face plane, and then finding the length PR. Apart...
Hi All SGI has just changed the licence on their OpenGL implementation to what is essentially an MIT licence http://www.linux.com/feature/148339 This means...
Adrian and Roger, It has been a while since I have written. I am looking for some help as usual. I would so like to have a program... to take any Waterman...
Hi Steve ... You can do this with an off2pov include file which overides the vertex drawing macro to draws them as appropriate tori. I have included one below,...
Hi Steve ... Great! I don't think it will affect your images but I spotted an obvious error in tor.inc. The line after "#macro rot_y_to_vec(vec)" should begin ...
