Function Documentation

◆ gcgBlinkingAlpha()

float gcgBlinkingAlpha ( )

Computes a value between 0 and 1 in function of time that can be used as opacity value to simulate blinking objects.

Returns: A value between 0 and 1 in function of time that is suitable to simulate blinking objects.

Since: 0.01.0

◆ gcgHeatColor() [1/2]

bool gcgHeatColor	(	float	normheat,
		VECTOR3	color
	)

Returns a color given a normalized "heat" value between 0 and 1. Uses a palette that partitions the unity with the colors dark blue, blue, bluish cyan, cyan, greenish cyan, green, greenish yellow, yellow, orange and red. All parameters have float type.

Parameters

[in]	normheat	value to be mapped into a 'heat' color. Values smaller than zero are clamped to 0. Values bigger than 1 are clamped to 1.
[out]	color	the resulting color heat.

Returns: true if the color is computed.

◆ gcgHeatColor() [2/2]

bool gcgHeatColor	(	double	normheat,
		VECTOR3d	color
	)

Returns a color given a normalized "heat" value between 0 and 1. Uses a palette that partitions the unity with the colors dark blue, blue, bluish cyan, cyan, greenish cyan, green, greenish yellow, yellow, orange and red. All parameters have double type.
