panda3d.core.LogicOpAttrib

from panda3d.core import LogicOpAttrib
class LogicOpAttrib

Bases: RenderAttrib

If enabled, specifies that a custom logical operation be performed instead of any color blending. Setting it to a value other than M_none will cause color blending to be disabled and the given logic operation to be performed.

New in version 1.10.0.
