Detailed Description

Blending singleton

The CIvfBlending singleton encapsulates OpenGL blending. An instance of the CIvfBlending class is retrieved using the getInstance() method. See the following code:

 CIvfBlendingPtr blending = CIvfBlending::getInstance();
 blending->enable();
 blending->setFunction(CIvfBlending::BF_SRC_ALPHA, CIvfBlending::BF_ONE_MINUS_SRC_ALPHA);
 ...
