Instance Method

union(with:)

Extends the voxel array to also cover the volume of the specified voxel array.

Declaration

func union(with voxels: MDLVoxelArray)

Parameters

voxels

The voxel array to combine with this voxel array.

Discussion

After a union operation, the voxel array contains voxels that were present either in the original array or in the specified array. That is, a union operation creates a voxel array that combines two volumes.

Performing a union, intersection, or difference operation clears out shell level information from all voxels in the array. (That is, the w component of every MDLVoxelIndex value in the voxel array is reset to 0.)

func intersect(with: MDLVoxelArray)

Reduces the voxel array to cover only the volume within both it and another voxel array.

func difference(with: MDLVoxelArray)

Reduces the voxel array to cover only the portion of its volume not covered by another voxel array.
