Hi,
ScalarsToColors should return values from black to white. But if the passed
value to getColor is larger than max also black is returned (see code below).
Code:
osg::Vec4 ScalarsToColors::getColor(float scalar) const
{
if(scalar<_min) return osg::Vec4(0.0f,0.0f,0.0f,0.0f);
if(scalar>_max) return osg::Vec4(0.0f,0.0f,0.0f,0.0f);
float c = (_min+scalar)/(_max-_min);
return osg::Vec4(c,c,c,1.0);
}
This code should be corrected to
Code:
osg::Vec4 ScalarsToColors::getColor(float scalar) const
{
if(scalar<_min) return osg::Vec4(0.0f,0.0f,0.0f,0.0f);
if(scalar>_max) return osg::Vec4(1.0f,1.0f,1.0f,1.0f);
float c = (_min+scalar)/(_max-_min);
return osg::Vec4(c,c,c,1.0);
}
Thank you!
Cheers,
Hartwig
