	)

Conservatively determines if a box [minvec, maxvec] in index space is constant or inactive. If there is doubt, it is reported as non-constant and active.

isconstant is true only if all voxels in the region have the same value isactive is false only if all the voxels in the region are inactive.

if isconstant is true, the returned value will the constant value.

inline

Gets values in the box [bbox.minvec(), bbox.maxvec()) Values are stored in the array values of size size that has to be at least bbox.volume() The order of values is give by: i + bbox.xsize() * (j + bbox.ysize() * k)

If returns true, values in bbox are constant and only values[0] is guaranteed to be assigned.
