QBlendEquationArguments Class
(Qt3DRender::QBlendEquationArguments)Encapsulates blending information: specifies how the incoming values (what's going to be drawn) are going to affect the existing values (what is already drawn). More...

Detailed Description
OpenGL pre-3.0: Set the same blend state for all draw buffers (one QBlendEquationArguments) OpenGL 3.0-pre4.0: Set the same blend state for all draw buffers, but can disable blending for particular buffers (one QBlendEquationArguments for setting glBlendFunc, n QBlendEquationArgumentss for enabling/disabling Draw Buffers) OpenGL 4.0+: Can set blend state individually for each draw buffer.
