Return a const reference to the ValueAccessor associated with this Stencil.
Return the coordinates of the center point of the stencil.
Return the value at the center of the stencil.
Return the value at the specified location relative to the center of the stencil.
Return the value from the stencil buffer with linear offset pos.
Return the gradient in world space of the trilinear interpolation kernel.
xyz | Floating point coordinate position. |
Return a const reference to the grid from which this stencil was constructed.
Return the trilinear interpolation at the normalized position.
xyz | Floating point coordinate position. Index space and NOT world space. |
Return true a bit-mask where the 6 lower bits indicates if the center of the stencil intersects the iso-contour specified by the isoValue.
The ordering of bit mask is ( -x, +x, -y, +y, -z, +z ), so to check if there is an intersection in -y use (mask & (1u<<2)) where mask is ther return value from this function. To check if there are any intersections use mask!=0u, and for no intersections use mask==0u. To count the number of intersections use __builtin_popcount(mask).
Return true if the center of the stencil intersects the iso-contour specified by the isoValue.
Return true if the center of the stencil intersects the.
iso-contour specified by the isoValue

Return the smallest value in the stencil buffer.
Initialize the stencil buffer with the values of voxel (i, j, k) and its neighbors.
ijk | Index coordinates of stencil center |
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.
ijk | Index coordinates of stencil center |
centerValue | Value of the center element of the stencil |
Initialize the stencil buffer with the values of voxel (x, y, z) and its neighbors.
Initialize the stencil buffer with the values of voxel (x, y, z) and its neighbors.
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.
Return linear offset for the specified stencil point relative to its center.
Set the value at the specified location relative to the center of the stencil.
