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.

class PySide2.Qt3DRender.Qt3DRender.QBlendEquationArguments([parent=None])

param parent:

PySide2.Qt3DCore.Qt3DCore.QNode

The constructor creates a new blend state object with the specified parent .
