NAME¶

SbColor - 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.

SYNOPSIS¶

#include <Inventor/SbColor.h> Inherits SbVec3f.

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. See Also:

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 *constrgb)¶

Construct and initialize an SbColor with the red, green and blue taken from given rgb array.

SbColor::SbColor (const floatr, const floatg, const floatb)¶

Construct and initialize an SbColor with the given red, green and blue values.

Member Function Documentation¶

SbColor & SbColor::setHSVValue (floathue, floatsaturation, floatvalue)¶

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 floathsv[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 (floathsv[3]) const¶

Return the color as a hue, saturation, value triplet. See Also:

SbColor & SbColor::setPackedValue (const uint32_trgba, 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 floattransparency = 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. See Also:
