DESCRIPTION¶

This class is used to represent an RGB color. Each component of the vector is a floating-point number between 0.0 and 1.0. There are routines to convert back and forth between RGB and HSV.

METHODS¶

SbColor(const SbVec3f vec3f)

SbColor(const float rgb[3])

SbColor(float r, float g, float b)

Constructors for color vector.

SbColor & setHSVValue(float h, float s, float v)

Sets value of color vector from 3 HSV (Hue, Saturation, and Value) components. Value is the same as brightness of the color.

SbColor & setHSVValue(const float hsv[3])

Sets value of color vector from array of 3 HSV components

void getHSVValue(float &h, float &s, float &v) const

Returns 3 individual HSV components

void getHSVValue(float hsv[3]) const

Returns an array of 3 HSV components

SbColor & setPackedValue(uint32_t rgba, float& transparency)

Sets value of color vector from an RGBA packed color value. The packed color format expressed in hexadecimal is 0xrrggbbaa, where

	rr is the red value
	gg is the green value
	bb is the blue value
	aa is the alpha value

uint32_t getPackedValue(float transparency = 0.0) const

Returns an RGBA packed color value, derived from the color vector and the passed transparency value. The alpha component is set to (1.0 - transparency) * 255, resulting in a hex value between 0 and 0xFF. If transparency not specified, alpha is set to 0xFF (opaque).
