1 Introduction

Black Tie

status: active

A noise library in Common Lisp

Introduction

This library is still in it's infancy and only supports very few types of noise yet.

It offers both heavily optimized (tested only on SBCL so far) and reference implementations if they are available.

License

This project is released under the simplified BSD license.

Features

• Perlin noise
• Simplex noise
• Voronoi noise

Documentation

None. See the examples/textures.lisp.

Function: perlin-noise-closure &optional PRECISION

Returns a closure which can be called just like PERLIN-NOISE-SINGLE-FLOAT. PRECISION will be used to determine the size of the precalculated perlin cube. The higher the precision to more elements will be in the cube and the more precise it will be (and the more memory it will consume). The number of elements in the cube is determined as PRECISION^3. NOTE: This does not give the same results for the same inputs as PERLIN-NOISE!
