It is uniform in the sense that phi and theta angle increments are the same. I understand that this means they have non-uniform distance on a sphere. If it helps, these are measurements of an antenna's radiation pattern. This uniform angle spacing is typical of many setups which measure the...

I have a uniform grid of data in spherical coordinates. e.g. theta = 0, 1, 2, ... 180 and phi = 0, 1, 2, ... 359 which forms a 2D matrix. I wish to rotate these points around a cartesian axis (x, y, z-axis) by some angle alpha. To accomplish this I currently do the following: 1. Convert to...
