Hi Roger ... As a compromise, if you are normally scanning in lines parallel to the x-axis. Then you would only need to store the current and previous two...
Hi Steve ... Does your FCC cell have a point at its centre? (If not, what was the calculation that gave the volume of 0.5?) ... They are included in the...
Hi Roger ... This is a bug, here is the offending line (twice) geom.get_verts()->push_back(vec3d(i, k, j)); I must learn the alphabet! Adrian. -- Adrian...
Adrian, ... 1x1xroot2....having exactly a volume of 0.5. That was wrong...geez...it is rather 1 x root2 x root2 edges for the fcc that yield its .5 volume. ...
Hi Steve ... But then 1 x root2 x root2 = 2 Does the cell you are thinking of have a point at its centre? ... Could you explain how you are doing this. Adrian....
Roger, In order to make that explosion program relevant to v,f,e,c it seems that since face centering is part and parcel of Antiprism already, that e and v and...
Adrian, ... Good question. i am confusing myself completely here. I have a drawing of an sc 1x1x1 cell. On the front face...i have drawn a square of edge root...
Hi Steve ... FCC is normlly thought of as having points on the face centres of the cubes. If you think of it as cuboctahedral arrangement of balls on the cubes...
Sorry, my brain has gotten up on the wrong side of bed ...this morning ... "In a lattice a primitive cell is a parallelepiped with vertices on lattice points,...
Hi Steve, ... Actually this sort of thing has been requested in Stella for a long while and has never been done. With good specs, this doesn't seem like it...
Hi Adrian, ... Realizing the z-points are tangent when they are equal to z of the centroid, I am rather anxious to put this into the z-intercept function....
Hi Adrian, Using if (z_near == (int)floor(cz+epsilon)) { makes the function more reliable so I will let it in. It tests the same as the previous floating...
Hi Adrian, (I wrote this note in Yahoo groups itself earlier and it ended up being rejected and sent to my email in box) ... long ... for ... enough ... Some...
Hi Roger ... That is right. Use the z values that you currently find as a starting point. Then, using long long integers, check each value to see if it is...
Hi Steve ... You are very welcome, and Kentyn is also welcome to use the source in his own program (permission is granted by the MIT Licence which is included...
Adrian, ... Thanks Adrian, indeed for already making this all public. I will see if he cares to join the forum at Antiprism next. I have only his initial...
Hi Adrian, ... the ... When you say long long integers there are several that come to mind. Which are available to c++. I thought the 18 quintillion variety...
Hi Roger ... You are right! I think g++ supports it, but for any distribution the calculations would really need to be done in C. ... It isn't really different...
Hi Adrian, ... was ... Would the whole program need to be extern C then? What is the highest available then, unsigned int? (unsigned long... I think long and...
Hi, There is an error in bravais extended help. I will edit it by something like this. Deleting the lines: "But this same logic would also argue that Face...
Hi Roger ... Just the code that used long long would have to go into a C file, and this could be linked against the other C++ code. ... An int is at least as...
Hi Adrian, ... The actual printf's are below. I changed the wording a bit from last night. I decided not to introduce FCT and BCT as the program doesn't take...
Hi, The Bravais vector and angle transformations of a=b=c and alpha=beta<>90<>gamma fits the Triclinic description. But Triclinic does not have 2 fold ...
Hi Adrian, I have the angles alpha, beta, and gamma parallel to vectors a,b,c (which I correspond to x,y,z). But the convention is to have them perpendicular...
