This is a GLSL fragment shader previewer, specifically designed to be compatible with fragment shaders written for ShaderToy (http://www.shadertoy.com).

The idea is that at some point you will be able to write a configuration file (see example-shadertoy.conf) to specify paths containing shadertoy fragment shaders. Then this program would show you a gallery of thumbnails or something equivalent, and let you pick any one to view fullscreen.
At the moment however the usage is pretty rudimentary. You'll have to specify the shader to load from the command line, as well as the ID of the texture you wish to use in each one of the four sampler slots. The IDs are printed when the program starts and loads textures during init, so run it once to see which is which.
Example: ./shadertoy myshader.glsl -t 0 -t 12 -t 3
- CMake project & build support
- added data folder for textures and example glsl shaders
- added dependencies as static libraries (freeglut, glew, imago2, libjpeg, libpng, zlib)
