On spherical harmonics possessing octahedral symmetry
share
In this paper, we present the implicit representation of one special class of real-valued spherical harmonics with octahedral symmetry. Based on this representation we construct the rotationally invariant measure of deviation from the specified symmetry. The spherical harmonics we consider have some applications in the area of directional fields design due to their ability to represent mutually orthogonal axes in 3D space not relatively to their order and orientation.
