(The library is also pushed to GitLab and Sourcehut but those sites are not monitored for support.)

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.

To Do

From Matrix #lispgamedev:matrix.org:

If anything, just grep for safety 0 and remove that ASAP :)

Or at least do it in a (locally (declare ..)) sparingly like around array accesses where you are sure your indices are correct.
