When rotating a cube, the cube representing the rotated particle will have some areas where there is no information.

As a consequence, a rotated particle appears as showing an "edge". Most Dynamo programs rotate the volume into an sphere. However, sometimes it is necessary to keep the edges, for instance during fourier compensation during average


See the effect here:

u1=dynamo_rot(rand(64,64,64),[45,45,45]); % rotates creating a spherical halo
u2=dpkgeom.rotation.sharpRot(rand(64,64,64),[45,45,45]); % rotates creating an edge
