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.
SbColor::SbColor | ( | void | ) |
Default constructor. The color value will be uninitialized.
Construct and initialize an SbColor with the red, green and blue values given by the v
vector.
Construct and initialize an SbColor with the red, green and blue taken from given rgb
array.
Construct and initialize an SbColor with the given red, green and blue values.
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°.

void SbColor::getHSVValue | ( | float & | h, |
float & | s, | ||
float & | v ) const |
Return the color as a hue
, saturation
, value
triplet.

void SbColor::getHSVValue | ( | float | hsv[3] | ) | const |
Return the color as a hue
, saturation
, value
triplet.
References getHSVValue().
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.
References SbVec3f::setValue().
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.
