template<typename DerivedType, typename GridT, bool IsSafe>
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().

template<typename DerivedType, typename GridT, bool IsSafe>
Initialize the stencil buffer with the values of voxel (i, j, k) and its neighbors. The method also takes a value of the center element of the stencil, assuming it is already known.
- Parameters
-
ijk | Index coordinates of stnecil center |
centerValue | Value of the center element of the stencil |
Definition at line 59 of file Stencils.h.
template<typename DerivedType, typename GridT, bool IsSafe>
template<typename IterType >
Initialize the stencil buffer with the values of voxel (x, y, z) and its neighbors.
- Note
- This version is slightly faster than the one above, since the center voxel's value is read directly from the iterator.
Definition at line 72 of file Stencils.h.
template<typename DerivedType, typename GridT, bool IsSafe>
template<typename RealType >
Initialize the stencil buffer with the values of voxel (x, y, z) and its neighbors.
- Parameters
-
xyz | Floating point voxel coordinates of stencil center |
This method will check to see if it is necessary to update the stencil based on the cached index coordinates of the center point.
