GLSL Noise Algorithms

Generic 1,2,3 Noise

float rand(float n){return fract(sin(n) * 43758.5453123);}

float noise(float p){
	float fl = floor(p);
  float fc = fract(p);
	return mix(rand(fl), rand(fl + 1.0), fc);

WebGL GLSL SAO (Scalable Ambient Obscurance) fragment shader. SAO is a more efficient method for computing SSAO (Screen-Space Ambient Occlusion). Converts the g-buffer to an occlusion buffer which estimates local ambient occlusion at each fragment in screen-space. For details on the technique itself, see: McGuire et al [12] http://graphics.cs.wi…
// total number of samples at each fragment
#define NUM_SAMPLES {{ numSamples }}
#define NUM_SPIRAL_TURNS {{ numSpiralTurns }}
#define USE_ACTUAL_NORMALS {{ useActualNormals }}
#define VARIATION {{ variation }}
