Return true a bit-mask where the 6 bits indicates if the center of the stencil intersects the iso-contour specified by the isoValue.
- Note
- There are 2^6 = 64 different possible cases, including no intersections!
The ordering of bit mask is ( -x, +x, -y, +y, -z, +z ), so to check if there is an intersection in -y use mask.test(2) where mask is ther return value from this function. To check if there are any intersections use mask.any(), and for no intersections use mask.none(). To count the number of intersections use mask.count().
