Detailed Description

maps x, y, z in parameter space to R, G, B with a faster algorithm

Simply calculates the RGB value of the current point from its place in the value space, normalizing to the interval [0..1].

Member Function Documentation

void Fastxyz2RGBColorManager::depthCueColor	(	double	wmax,
		double	wmin,
		double	w,
		const VecMath::Vector< 4 > &
	)		[virtual]

Todo:

implement me!

Implements ColorManager.

Color Fastxyz2RGBColorManager::getColor

(

const VecMath::Vector< 4 > &

x

)

[virtual]

Find the color of a given point.

If the point is not stored in the map of already defined points, calculate its color by averaging over the nearest neighboring points and store its value for future use

Parameters:

x	four-dimensional coordinate for which the color is sought

Implements ColorManager.

void Fastxyz2RGBColorManager::setFunction

(

Displayable *

_f

)

[virtual]

Parameters:

_f	new Function to manage

Reimplemented from ColorManager.
