voxelBoundingBox(atIndex:)
Returns the extent of the specified voxel’s volume in the world coordinate space of the asset from which the voxel array was created.
Declaration
func voxelBoundingBox(atIndex index: MDLVoxelIndex) -> MDLAxisAlignedBoundingBoxParameters
- index:
An index describing the location of a voxel within the three-dimensional grid of the voxel array. (The w component is ignored for this query.)
Return Value
The bounding box for the single voxel at the specified index, in the world coordinate space of the asset from which the voxel array was created.
Discussion
The coordinate space for spatial locations of voxels is the world space of the asset from which the voxel array was created, or for voxel arrays created with the init(data:boundingBox:voxelExtent:) initializer, the bounding box specified at initialization.
