Geometry

Utility functions for generating sensor grids and parsing Radiance geometry primitives. These are commonly used to prepare inputs for ray tracing workflows.

frads.gen_grid

gen_grid(polygon, height, spacing)

Generate a grid of points for orthogonal planar surfaces.

Parameters:

Name	Type	Description	Default
polygon	Polygon	a polygon object	required
height	float	points' distance from the surface in its normal direction	required
spacing	float	distance between the grid points	required

Returns: List of the points as list

frads.parse_polygon

parse_polygon(primitive)

Parse a primitive into a polygon.

Parameters:

Name	Type	Description	Default
primitive	Primitive	a dictionary object containing a primitive	required

Returns: A Polygon object
