Perhaps it would help if you told us what application you are going to use them 
for? You can straightforwardly make a regular tetrahedral grid of points that 
fit in your box at whatever density you like. Which is more important: maximal 
(average) distance between neighbors or avoiding regularity? If you need to 
strike a balance between them, then you may want to look into low-discrepancy 
sequences:
