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. The build defaults to Vulkan renderer, to use OpenGL set "RENDERER:=opengl" in local.mk.

Windows: There is a Visual Studio 2015 solution in /windows/SMAADemo.sln. You will need cmake, Python3, SDL2 and Vulkan SDK. You also need to build the following libraries from the included sources under /foreign: SPIRV-Tools.lib SPIRV-Tools-comp.lib SPIRV-Tools-opt.lib spirv-cross-core.lib spirv-cross-glsl.lib

You can use the included windows/build-foreign.bat file to automatically build the required libraries with cmake.

Usage

Command line options: "--debug" - Enable renderer debugging. "--trace" - Enable renderer tracing. "--nocache" - Don't load shaders from cache. "-f", "--fullscreen" - Start in fullscreen mode. "novsync" - Disable vsync. "--width <value>" - Specify window width. "--height <value>" - Specify window height. "<file path> ..." - Load specified image(s).

Key commands: A - Toggle antialiasing on/off C - Re-color cubes D - Cycle through debug visualizations. Hold SHIFT to cycle in opposite direction. F - Toggle fullscreen H - Print help M - Change antialiasing method (SMAA/FXAA) Q - Cycle through AA quality levels. Hold SHIFT to cycle in opposite direction. V - Toggle vsync LEFT/RIGHT ARROW - Cycle through scenes SPACE - Toggle camera rotation ESC - Quit
