static

A function to provide an adjusted hue when interpolating to an unsaturated color in Msh space

Parameters

[in]	Input	M value to adjust hue to
[in]	Input	s value to adjust hue to
[in]	Input	h value to adjust hue to
[in]	Second	input M value to adjust hue to
[out]	Adjusted	hue value

◆ correctiveDivergentInterpolation()

static void VAPoR::TFInterpolator::correctiveDivergentInterpolation	(	float	rgb1[3],
		float	rgb2[3],
		float	output[3],
		float	interp
	)

static

Interpolation algorithm that applies a corrective white space between two saturated color control points

Parameters

[in]	RGB1	Start point color for diverging color map
[in]	RGB2	End point color for diverging color map.
[in]	The	output interpolated RGB value in the divergent map
[in]	The	interpolation weight of the current color in the color map
[in]	Set	whether we insert white space between two saturated color control points

◆ divergentInterpolation()

static int VAPoR::TFInterpolator::divergentInterpolation	(	float	rgb1[3],
		float	rgb2[3],
		float	output[3],
		float	interp,
		bool	corrective = `false`
	)

static

Interpolation algorithm to generate a single interpolated color in a diverging color map.

Parameters

[in]	RGB1	Start point color for diverging color map
[in]	RGB2	End point color for diverging color map.
[in]	The	output interpolated RGB value in the divergent map
[in]	The	interpolation weight of the current color in the color map
[in]	Set	whether we insert white space between two saturated color control points

static

Generate the complete diverging color map using the Moreland technique from RGB1 to RGB2, placing "white" in the middle. The number of points given by the "numColors" variable controls the resolution of the color map.

Parameters

[in]	RGB1	Start point color for diverging color map.
[in]	RGB2	End point color for diverging color map.
[in]	Number	of colors to generate in the new color map.

Return values

Return status, 1 = success
