Fragment Shaders

You can run fragment shaders like GLSL Sandbox on VEDA.

Fragment shaders must be named like *.frag.
Create a file foo.frag like this:

precision mediump float;
uniform float time;
uniform vec2 resolution;

void main() {
    vec2 uv = gl_FragCoord.xy / resolution.xy;
    gl_FragColor = vec4(uv, 0.5 + 0.5 * sin(time), 1.0);

Then save it and hit ctrl-enter to run it.
VEDA will show the result on the background.
