SMAA Demo

This is a small program demonstrating the use of the Subpixel Morphological Antialiasing implementation from https://github.com/iryoku/smaa/.

Building
========

Linux: Go to /binaries and type make. To change build settings copy example.mk to local.mk in the same directory. You only need to include changed lines in local.mk.

Emscripten: Go to /emscripten and type make. On Windows you will need to run this through MinGW shell configured for Emscripten. Change build settings with local.mk as on Linux.
Emscripten version is currently broken.

Windows: There is a Visual Studio 2013 solution in /windows/SMAADemo.sln. You will need SDL2 headers and Windows libraries.


Usage
=====

Command line options:
"--gles" - Use OpenGL ES.
"--gldebug" - Enable OpenGL debugging.
"--noinstancing" - Disable instancing.
"--dsa <mode>" - Select DSA mode: "arb", "ext", "none".
