Tileable procedural textures

Collection of tileable procedural textures:

  • value noise (with derivatives and gradient rotation)
  • gradient noise (with derivatives)
  • perlin noise (with gradient rotation)
  • checkerboard (diagonal)
  • patterns: tile weaves, cross, waves, stairs
  • celullar noise (with derivatives and phase)
  • metaballs (variant of cellular noise)
  • voronoi (edges, cells)
  • fbms (value, perlin, voronoi and derivative)
  • domain warping (fbnm and gradient curl)
  • hexagonal grid and noise variant

Q and R factors

The Q and R values of the warp can be used to mix different patterns/colors:

    vec2 q, r;
    float f = fbmWarp(p, scale, factors, octaves, shifts, phase, gain, vec2(lacunarity), slopeness, 0.0, true, 0.0, q, r);
        
    col = mix(vec3(0.1,0.5,0.8), vec3(0.6,0.6,0.3), clamp((f * f) * 8.0, 0.0, 1.0));
    col = mix(col, vec3(0.0, 0.1, 0.05), length(q));
    col = mix(col, vec3(0.8, 0.8, 0.8), r.x);
    col = mix(col, col * vec3(0.8, 0.4, 0.2), 0.5 * pow(length(r), 4.0));

fbm-warp-factors
