Instance Method

voxelIndices

Returns a data object containing all voxels within the voxel array.

Declaration

- (NSData *)voxelIndices;

Return Value

A data object containing MDLVoxelIndex values.

Discussion

The returned NSData object contains an array of MDLVoxelIndex values describing the locations of voxels within the voxel array as well as their volumetric relationship to the object modeled by the voxel array.

Calling this method is equivalent to calling the voxelsWithinExtent: method with the value of the voxelIndexExtent property.

- voxelExistsAtIndex:allowAnyX:allowAnyY:allowAnyZ:allowAnyShell:

Returns a Boolean value indicating whether the voxel array contains voxel data for the specified index.

- voxelsWithinExtent:

Returns a data object containing all voxels within the specified volume.
