This app simply draws two (shaded) triangles, which is basically a native offline variant of an older version of Shadertoy.

• Edit OpenGL fragment shader files (GLSL 1.10) with your favorite text editor and watch saved changes appear near instantly
• Modify uniform values by dragging to see the effects in realtime
• Load and store uniform values to disk
• Built-in 3D camera with keyboard controls (WASD for moving, arrow keys for looking around)
• Load textures, cubemaps and HDR images
