Basic GLSL shaders (three.js)

frag.glsl

uniform float time;
uniform vec2 resolution;
uniform vec3 color;

void main() {
  gl_FragColor = vec4(color, 1.);
}

vert.glsl

varying vec3 vUv;

void main() {
  vUv = position;

  vec4 modelViewPosition = modelViewMatrix * vec4(position, 1.0);
  gl_Position = projectionMatrix * modelViewPosition;
}
