CountIntersectingVoxels

public class CountIntersectingVoxels
extends Object

Counts the number of intersecting voxels where bytes are encoded as region memberships.

This class provides methods to count intersecting voxels between two bounded voxel sets, optionally considering a global mask.

Constructor Details

CountIntersectingVoxels

public CountIntersectingVoxels(byte regionMembershipFlag)

Creates a new instance with a specific region membership flag.

Parameters:

regionMembershipFlag - the byte value representing region membership

CountIntersectingVoxels

public CountIntersectingVoxels(PredicateRegionMembership predicate)

Method Details

count

public int count(BoundedVoxels<UnsignedByteBuffer> voxels1,
 BoundedVoxels<UnsignedByteBuffer> voxels2)

Counts the number of intersecting voxels between two bounded voxel sets.

Parameters:

voxels1 - the first set of bounded voxels

voxels2 - the second set of bounded voxels

Returns:

the count of intersecting voxels

countMasked

public int countMasked(BoundedVoxels<UnsignedByteBuffer> voxels1,
 BoundedVoxels<UnsignedByteBuffer> voxels2,
 Voxels<UnsignedByteBuffer> maskGlobal,
 byte onMaskGlobal)

Counts the number of intersecting voxels between two bounded voxel sets, considering a global mask.

Parameters:

voxels1 - the first set of bounded voxels

voxels2 - the second set of bounded voxels

maskGlobal - the global mask to apply during counting

onMaskGlobal - the value in the global mask that indicates a voxel should be considered

Returns:

the count of intersecting voxels that also satisfy the global mask condition
