API & MCP

Everything a person can do on Seamless Noise Texture Generator, a program or AI agent can do with the same inputs and get the identical result.

HTTP API

Seamless Noise Texture Generator

Pick Perlin, value, simplex or Voronoi (Worley) noise, set the cells per tile, octaves, persistence and an optional domain warp, and download a seamless grayscale PNG, a 16-bit height PNG and a 2 × 2 repeat that proves the tiling. The result opens as a graph in Renderloom Material Nodes.

Inputs of Seamless Noise Texture Generator
Field	Type	Default	Description
`kind`	select (perlin, value, simplex, worley-f1, worley-f2, worley-edge, worley-cells)	"perlin"	Noise type
`style`	select (fbm, turbulence, ridged)	"fbm"	Octave style (Perlin, value, simplex)
`scaleX`	integer	6	Horizontal cells per tile
`scaleY`	integer	6	Vertical cells per tile
`octaves`	integer	5	Octaves
`persistence`	number	0.5	Persistence (gain per octave)
`contrast`	number	1	Contrast
`jitter`	number	0.9	Voronoi jitter
`warp`	number	0	Domain warp (fraction of the tile)
`seed`	integer	0	Seed
`size`	integer	256	Texture size (px)
