Image to Normal Map

Upload a texture and Pixlane reads its luminance as a height field, then derives surface normals with a Sobel gradient pass and encodes them into the usual RGB convention. Pick the green-channel direction your engine expects — OpenGL, Blender and Unity read +Y up, while Direct3D and Unreal read +Y down — because the wrong one flips lighting on every surface.

Perlin & Simplex Noise Generator — fBm Octaves

Generate Perlin, Simplex, Worley, and value noise with tunable octaves, persistence, lacunarity, and seed. Perfect for game development textures, procedural terrain, shader backgrounds, and generative art.

Frequently Asked Questions

What is Perlin noise?

Perlin noise is a gradient-based pseudo-random noise function producing smooth, natural-looking patterns used for terrain, clouds, textures, and procedural animation.

What are octaves and fBm?

Fractional Brownian Motion (fBm) sums multiple octaves (frequencies) of noise scaled by persistence. More octaves = more detail; higher persistence = rougher output.

What is the difference between Perlin and Simplex?

Simplex noise (Ken Perlin's later work) is faster, has fewer directional artifacts, and scales better to higher dimensions. Both serve similar use cases.

Is the output tileable?

Enable the tileable option for seamless wrap-around — required for texture maps in game engines.
