Method Details

erode

public static ObjectMask erode(ObjectMask object,
 int iterations,
 boolean useZ)
                        throws CreateException

Performs a morphological erosion on an ObjectMask.

Parameters:

object - the object-mask to perform the erosion on.

iterations - how many iterations of erosion to perform.

useZ - whether to use the Z dimension or not during the erosion.

Returns:

a newly created BinaryVoxels<UnsignedByteBuffer> showing voxels after the erosion operation was applied.

Throws:

CreateException

erode

public static ObjectMask erode(ObjectMask object,
 int iterations,
 boolean useZ,
 Optional<AcceptIterationPredicate> postcondition)
                        throws CreateException

Performs a morphological erosion on an ObjectMask - with a postcondition.

Parameters:

object - the object-mask to perform the erosion on.

iterations - how many iterations of erosion to perform.

useZ - whether to use the Z dimension or not during the erosion

postcondition - conditions applied after each iteration of the erosion, otherwise no more iterations occur. Note that these are applied on an inverted version of voxels.

Returns:

a newly created BinaryVoxels<UnsignedByteBuffer> showing voxels after the erosion operation was applied.

Throws:

CreateException

erode

public static BinaryVoxels<UnsignedByteBuffer> erode(BinaryVoxels<UnsignedByteBuffer> voxels,
 int iterations,
 boolean useZ,
 Optional<Predicate<Point3i>> precondition)
                                              throws CreateException

Performs a morphological erosion on a BinaryVoxels<UnsignedByteBuffer> voxels.

Parameters:

voxels - the voxels to perform the erosion on.

iterations - how many iterations of erosion to perform.

useZ - whether to use the Z dimension or not during the erosion.

precondition - if defined, a condition which must be satisfied on a voxel, before any voxel can be dilated.

Returns:

a newly created BinaryVoxels<UnsignedByteBuffer> showing voxels after the erosion operation was applied.

Throws:

CreateException
