Noise | Random 1D - Shader Learning

Random 1D

In a shader program, implement the random function that generates a pseudo-random value in the range of [-1, 1] for a given input using a sine wave. Use the value 12.34 as the multiplier for the sine argument and 1234.5678 as the multiplier for the sine output.

uniform vec2 iResolution;

float random(float x) {

return 0.0;

}

void main() {

vec2 uv = gl_FragCoord.xy / iResolution.xy;

float noiseValue = random(uv.x);

noiseValue = noiseValue * 0.5 + 0.5;

gl_FragColor = vec4(vec3(noiseValue), 1.0);

}
