Detailed Description

virtual room to do some light-experiments.

The basic use of this class is to derive the size/pattern of the light-influence FON for a single tree. It uses SolarRadiation for the calculation of global radiation and HemiGrid to calculate and store the results. This calculation is done for each node of a 3D space and afterwards accumulated into a 2D pattern.

calculateFullGrid()

void LightRoom::calculateFullGrid

(

)

calculate a hemigrid for each node of the grid (store results in m_3dvalues).

Returns

fraction of "blocked" radiation [0..1]. -1: point inside the object

calculateGridAtPoint()

double LightRoom::calculateGridAtPoint	(	const double	p_x,
		const double	p_y,
		const double	p_z,
		bool	fillShadowGrid = true
	)

calculate a full hemiview image from given point

		const double	dimy,
		const double	dimz,
		const double	cellsize,
		const double	hemigridsize,
		const double	latitude = 48.,
		const double	diffus_frac = 0.5
	)

setup the spatial grid.

setup routine.

sets up datastructures (3d space, hemi grids)

Parameters

dimx	size of space in x direction [m]
dimy	size of space in y direction [m]
dimz	size of space in z direction [m]
cellsize	metric length of cells (used for all 3 dimensions).
