Noiz

A simple, configurable, blazingly fast noise library built for and with Bevy. See the book for a taste.

Noiz is:

• Simple
• Extendable
• Blazingly fast (meant for realtime use)
• Easy to use in Bevy
• Built in pure rust
• Consistent between platforms (with a feature flag)
• Serializable
• Reflectable
• Readable
• Under development (as I have time and features are requested)
• Free and open source forever (feel free to open issues and prs!)
• No Std compatible

Noiz is not:

• Spelled correctly (noise was already taken)
• Mathematically precise (only supports f32 types for now)
• Fully optimized yet (algebraic float math is not stable in rust yet)
• Meant to replace art tools for asset generation
• Meant to be standalone (you'll want to also depend on either bevy_math or bevy.)

What Makes Noiz Unique?

• Noiz is powered by a custom random number generator built on a hash function instead of the traditional permutation table. This gives competitive performance while using less memory and reducing tiling artifacts.
• Noiz seamlessly integrates with Bevy!
• Noiz changes seed automatically between octaves (which prevents some artifacting common in other libraries).
• Noiz is endlessly cusomizable. Really, the combinations and settings are limitless!
• Noiz is no_std.
• Noiz supports all your favorite noise types. If you see one that's missing, please open an issue!
• Noiz supports noise derivatives and gradiesnts, allowing fast erosion approximations, analytical normals, etc.
• Noiz supports many noise types that other libraries do not, for example, distance-to-edge worly noise and smooth worly noise.
• Noiz has good documentation and a book.
• Noiz is faster than many other libraries (see the book for benchmarks).

In addition to rust docs, Noiz has a book available here. This explains how to use Noiz in practice with much more detail than the API reference. Also see the interactive examples for inspiration.
