2 – FXAA demo

With all these good arguments, I decided to code a small GeeXLab demo to test the GLSL version of FXAA II.

You can download the demo here:
Download GXL - FXAA demo Version 2011.04.05



Unzip the archive somewhere, and run the FXAA_Demo.exe. FXAA is enabled by default. Press SPACE to enable/disable FXAA.

The main source code file of the demo is DEMO.xml. The FXAA post processing shader is in the PostFX_FXAA_Lib.xml file.

As you can see in the following screenshots, FXAA works rather well:
