setGlobalDepthAlpha( state, near, far ) alias: CubicVR.GLCore.setDepthAlpha()
Enable/Disable and update the near/far linear depth for using Depth Alpha.
When Depth Alpha is enabled the resulting Alpha channel after rendering will contain the depth component in linear form 0.0->1.0 representing near/far planes. This is typically used in conjunction with post-process shaders to provide depth information to Depth-of-Field (DOF), Screen-Space Ambient Occlusion (SSAO) or other effects.
Parameters:
-
state: true or false to enable or disable Depth Alpha respectively. -
near: the view NEAR clipping plane. -
far: the view FAR clipping plane.
Returns:
none
