From 805d9478109e76ca221f202ff152bae685f77ff4 Mon Sep 17 00:00:00 2001 From: Habib Gahbiche Date: Mon, 29 Mar 2021 07:44:27 +0200 Subject: Compositor: Add Anti-Aliasing node This is an implementation of Enhanced Subpixel Morphological Antialiasing (SMAA) The algorithm was proposed by: Jorge Jimenez, Jose I. Echevarria, Tiago Sousa, Diego Gutierrez This node provides only SMAA 1x mode, so the operation will be done with no spatial multisampling nor temporal supersampling. See Patch for comparisons. The existing AA operation seems to be used only for binary images by some other nodes. Using SMAA for binary images needs no important parameter such as "threshold", so we perhaps can switch the operation to SMAA, though that changes existing behavior. Notes: 1. The program code assumes the screen coordinates are DirectX style that the vertical direction is upside-down, so "top" and "bottom" actually represent bottom and top, respectively. Thanks for Habib Gahbiche (zazizizou) to polish and finalize this patch.
