Detailed Description¶
The SbColor class contains the red, green and blue components which make up a color value.
This class is used within other classes in Coin. It inherits the SbVec3f class, interpreting the 3 component vector as a vector in the RGB cube where the red, green and blue components corresponds to x, y and z respectively.
SbColor also adds a few extra methods for convenient handling of setting and getting color values as 32 bit packed values or as HSV values.

Constructor & Destructor Documentation¶
SbColor::SbColor (void)¶
Default constructor. The color value will be uninitialized.
SbColor::SbColor (const SbVec3f & v)¶
Construct and initialize an SbColor with the red, green and blue values given by the v vector.
SbColor::SbColor (const float *const rgb)¶
Construct and initialize an SbColor with the red, green and blue taken from given rgb array.
SbColor::SbColor (const float r, const float g, const float b)¶
Construct and initialize an SbColor with the given red, green and blue values.
Member Function Documentation¶
SbColor & SbColor::setHSVValue (float hue, float saturation, float value)¶
Set the color as a hue, saturation, value triplet. The hue component should be normalized to within [0, 1] before you call this method, where 0 is equal to 0° and 1 is equal to 360°.
See also
SbColor & SbColor::setHSVValue (const float hsv[3])¶
Set the color as a hue, saturation, value triplet. The hue component should be normalized to within [0, 1] before you call this method, where 0 is equal to 0° and 1 is equal to 360°.
See also
void SbColor::getHSVValue (float & h, float & s, float & v) const¶
Return the color as a hue, saturation, value triplet.
See also
void SbColor::getHSVValue (float hsv[3]) const¶
Return the color as a hue, saturation, value triplet.
See also
SbColor & SbColor::setPackedValue (const uint32_t rgba, float & transparency)¶
Set the color value as a 32 bit combined red/green/blue/alpha value. Each component is 8 bit wide (i.e. from 0x00 to 0xff), and the red value should be stored leftmost, like this: 0xRRGGBBAA.
The transparency value is not stored internally in SbColor, just converted to a transparency value in [0, 1] and returned in the transparency field. A value of 1.0 means completely transparent and a value of 0.0 is completely opaque.
See also
uint32_t SbColor::getPackedValue (const float transparency = 0.0f) const¶
Return color as a 32 bit packed integer in the form 0xRRGGBBAA. The transparency part of the return value is taken from the supplied transparency argument.
