    • Updates the size of this effect.

      You may override this method if you want to be informed about the size of the backbuffer/canvas. This method is called before initialize and every time the size of the EffectComposer changes.

        The width.

      • height: number

        The height.

    • Updates this effect by performing supporting operations.

      This method is called by the EffectPass right before the main fullscreen render operation, even if the blend function is set to SKIP.

      You may override this method if you need to update custom uniforms or render additional off-screen textures.

      Parameters
