Hi Roger ... The color_vef() function has changed so that is okay. I am not sure why the others don't cause a problem, but it may be because they are contained

Update (in which we find a 'Catch-22'....) (S'scuse, Adrian, Roger; I'm talking to myself a bit here....) -- I have a filewriter function which takes a pointer

Hi Roger ... If Antiprism is built in a directory called anti you can build a program against it from a neighbouring directory like this g++ -W -Wall -o prog

... Hi Adrian ... Yes I suppose so.... With the OpenGL, the "callback function" seems to be what "calls back" the operation of redrawing the screen.... ...

Hi John ... A normal situation is that there is a framework that will carry out particular tasks in particular situations. You write a function that carries

Hi Adrian, I have been working on a slight tweak for bravais and lat_util which will allow the radius to be taken directly from the polyhedral container

Hi Adrian, ... I the "do_convex_hull" I could only test if there were less than 4 points. But that is enough in most cases. Occasionally I will get a polygon,

Hi Adrian, ... How would one compile just a standalone program like this? I compiled it by putting it into my Makefile but I think there should a command line

Hi Roger ... The symmetry code currently fails when the vertices don't have a a three dimensional convex hull. I need to add handling for this. I think I

Hi Roger ... I have included an example program below that uses a C approach. I imagine you would include the most useful blend functions in the library, but a

Adrian and Roger, Just found this....a way to number the 230 crystal classes from a J. D. Bernal in 1923. Long paper...but look after page 113 in particular.

Roger, ... Yes sir....exactly. ... Yes. (i think the documentation has -T at 0-256...and should be removed then.) ... Indeed...i like this a lot too. ... i

Roger Kaufman — Mon, 16 Nov 2009 16:02:27 GMT

Hi Steve, ... I think this is what you want. If not let me know. You may want the container displayed transparently over the product. In that case we must pass

Steve — Mon, 16 Nov 2009 13:31:08 GMT

Roger, is this possible ? take a lattice that MUST enclose a given convex hull and get a point set by removing those points exterior to that hull ? then we
