NAME SbColor - color vector class INHERITS FROM SbVec3f SYNOPSIS #include <Inventor/SbColor.h> Methods from class SbColor: SbColor(const SbVec3f vec3f) SbColor(const float rgb[3]) SbColor(float r, float g, float b) SbColor & setHSVValue(float h, float s, float v) SbColor & setHSVValue(const float hsv[3]) void getHSVValue(float &h, float &s, float &v) const void getHSVValue(float hsv[3]) const SbColor & setPackedValue(uint32_t rgba, float& transparency) uint32_t getPackedValue(float transparency = 0.0) const Methods from class SbVec3f: SbVec3f cross(const SbVec3f &v) const float dot(const SbVec3f &v) const SbBool equals(const SbVec3f v, float tolerance) const SbVec3f getClosestAxis() const const float * getValue() const void getValue(float &x, float &y, float &z) const float length() const void negate() float normalize() SbVec3f & setValue(const float v[3]) SbVec3f & setValue(float x, float y, float z) SbVec3f & setValue(const SbVec3f &barycentic, const SbVec3f &v0, const SbVec3f &v1, const SbVec3f &v2) float & operator [](int i) const float & operator [](int i) SbVec3f & operator *=(float d) SbVec3f & operator /=(float d) SbVec3f & operator +=(const SbVec3f &u) SbVec3f & operator -=(const SbVec3f &u) SbVec3f operator -() const SbVec3f operator *(const SbVec3f &v, float d) SbVec3f operator *(float d, const SbVec3f &v) SbVec3f operator /(const SbVec3f &v, float d) SbVec3f operator +(const SbVec3f &v1, const SbVec3f &v2) SbVec3f operator -(const SbVec3f &v1, const SbVec3f &v2) int operator ==(const SbVec3f &v1, const SbVec3f &v2) int operator !=(const SbVec3f &v1, const SbVec3f &v2) 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 RGBA component values range from 0 to 0xFF (255). The returned transparency value is a floating point value between 0.0 (opaque) and 1.0 (completely transparent). It is derived from the alpha component of the RGBA color. 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). FILE FORMAT/DEFAULTS Color { }
