Hi, I am actually trying to understand the OSG Volume Example, The alpha coefficient allow me to play with the extinction coefficient, but have problem to use the transfer function. What does represent the first parameter when we set a new Color ?
transferFunction->setColor(value, osg::Vec4(1.0,1.0,1.0,apha)); this line permit normally to set a transferControl point I think... in this case does the function will color all the vortex between ? and my value with this color and the opacity in parameter ? Thank you!
