Return the value from the stencil buffer with linear offset pos.
- Note
- The default (pos = 0) corresponds to the first element which is typically the center point of the stencil.
Return the value at the specified location relative to the center of the stencil.
Return the gradient computed at the previously buffered location by second-order central differencing.
- Note
- This method should not be called until the stencil buffer has been populated via a call to moveTo(ijk).
Return a const reference to the grid from which this stencil was constructed.
Return true if the center of the stencil intersects the iso-contour specified by the isoValue.
Return the Laplacian computed at the previously buffered location by second-order central differencing.
- Note
- This method should not be called until the stencil buffer has been populated via a call to moveTo(ijk).
Return the largest value in the stencil buffer.
Return the mean value of the current stencil.
Return the mean curvature at the previously buffered location.
- Note
- This method should not be called until the stencil buffer has been populated via a call to moveTo(ijk).
Return the mean curvature multiplied by the norm of the central-difference gradient. This method is very useful for mean-curvature flow of level sets!
- Note
- This method should not be called until the stencil buffer has been populated via a call to moveTo(ijk).
Return the median value of the current stencil.
Return the smallest value in the stencil buffer.
void moveTo |
( |
const Coord & |
ijk | ) |
|
|
inlineinherited |
Initialize the stencil buffer with the values of voxel (i, j, k) and its neighbors.
- Parameters
-
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.
- Parameters
-
ijk | Index coordinates of stnecil 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.
- Note
- This version is slightly faster than the one above, since the center voxel's value is read directly from the iterator.
void moveTo |
( |
const Vec3R & |
xyz | ) |
|
|
inlineinherited |
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.
Set the value at the specified location relative to the center of the stencil.
Return the size of the stencil buffer.
