Abstract: In one embodiment, a method receives voxel coordinates of voxels in a second volume in the image and generates links for the voxels in the second volume in x, y, and z directions. An angle twist is calculated for the links of the voxels based on the voxel coordinates for each voxel in the second volume. Links for adjacent voxels along each of an x, y, and z axis are twisted by different angle gradations as distance along the axis increases. The method calculates an orientation of the links for the second volume. The second orientation is different from a first orientation of the links for the first volume. The links for the voxels of the second volume are rendered in the three dimensional space where the links are rendered with the calculated angle twist in the x, y, and z directions and the second orientation.
