Detailed Description

Multi-dimensional (aka crystal) geometries.

Function Documentation

pure()

EX bool hr::crystal::pure

(

)

Crystal can be bitruncated either by changing variation to bitruncated. In case of the 4D Crystal, the standard HyperRogue bitruncation becomes confused by having both the original and new vertices of degree 8. Hence Crystal implements its own bitruncation, which is selected/checked by setting ginf[gCrystal].vertex to 3. Additionally, this lets us double bitruncate. Function pure() checks for both kinds of bitruncation (or any other variations).

Variable Documentation

FULLSTEP

const int hr::crystal::FULLSTEP = 2

in the "pure" form, the adjacent vertices are internaly spaced by 2

HALFSTEP

const int hr::crystal::HALFSTEP = 1

to make space for the additional vertices which are added in the bitruncated version

PERIOD

const int hr::crystal::PERIOD = 2 * FULLSTEP

with variations, the connections of the vertex at coordinate v+FULLSTEP mirror the connections of the vertex at coordinate v. Therefore, the period of our construction is actually 2*FULLSTEP.
