Detailed Description

HemiGrid represents a grid covering the hemisphehre as well as some operations.

The sky is modeled as equally sized tiles. Coordinate system: azimuth: angle between -pi .. +pi, where 0=south direction elevation: 0: horizon - pi/2 (90°)

inline

get azimuth angle associated with given index.

Returns

0 (North) -> pi/2 (West) -> pi (South) -> 3pi/2 (East)

clear()

(

double

SetWith = 0.

)

dumpGrid()
