ColorRange is a ScalarsToColors object to define a color spectrum for a scalar range.
An optional vector of colors may be passed in at construction time. The range of colors will be mapped to the scalar range, and interpolation between the colors will be performed as necessary. By default, the color range will run Red-Yellow-Green-Cyan-Blue.
osgSim::ColorRange::ColorRange | ( | float | min, |
float | max | ||
) |
Constructor for a ColorRange with a default list of colors set to Red-Yellow-Green-Blue-Cyan.
min | minimum scalar value |
max | maximum scalar value |
osgSim::ColorRange::ColorRange | ( | float | min, |
float | max, | ||
const std::vector< osg::Vec4 > & | colors | ||
) |
Constructor for a ColorRange.
min | minimum scalar value |
max | maximum scalar value |
colors | optional range of colors, |
osg::Vec4 osgSim::ColorRange::getColor | ( | float | scalar | ) | const [virtual] |
Get the color for a given scalar value.
Reimplemented from osgSim::ScalarsToColors.
void osgSim::ColorRange::setColors | ( | const std::vector< osg::Vec4 > & | colors | ) |
Set the range of colors.
