# Theta

Features:[1] real-valued spherical harmonicsusing real coefficients[2] support flexible band intervals(l=0:dl:L) including both full bandSH (dl=1) and even order only SH (dl=2)[3] evaluate both function valuesf(theta,phi) and the derivativesof f w.r.t theta and phi. Can be usedfor finding peaks...

A few days ago I was in need of uniformly random points generation on the surface of sphere. I suddenly discovered that common parametrization with 2 angles is useless, it gathers too many points in the poles. At MathWorld you can find the complete demonstration, here the main lines:To pick a...

Often three dimensional objects need to be reconstructed from planar images that are taken from slices in destructive testing. This sometimes requires the manual selecting of control points, but in this case geometries of the solid can be exploited to realign the images automaticaly. This is an...
