画单位球体的以颜色为渐近的色彩图

由方位角 高程 密度等来构建-Plots the intensity (as color) of a number of points on a unit sphere.

Input:

　azimuth (phi), in degrees

　elevation (theta), in degrees

　intensity (optional, if not provided, a green sphere is produced)

　All inputs must be vectors or matrices of the same size.

　Data does not have to be evenly spaced. When there aren t enough points

　to draw a smooth sphere, additional points (with color) are
