dhart.viewanalysis.SphericallyDistributeRays

dhart.viewanalysis.SphericallyDistributeRays(num_rays: int, upward_fov: float = 50, downward_fov: float = 70) → ViewAnalysisDirections

Distribute directions evenly in a sphere.

This is the same algorithm used in the other view analysis functions, so the output of this can be used to get the hit points of results from SphericalViewAnalysis.

Parameters:

• num_rays – the number of directions to generate, Note that the actual number may be higher

• upward_fov – the maximum angle upwards to generate directions for in degrees

• downward_fov – the maximum angle downwards to generate directions for in degrees

Returns:

A two dimensional array of directions
