# Seismic
[](https://ci.solo-studios.ca/job/PolyhedralDev/job/Seismic/job/master/)
[](https://github.com/PolyhedralDev/Seismic/tags)
[](https://terra.polydev.org/contact.html)
A Java sampler, math, type, and utility library, primarily for use in [Polyhedral Development](https://github.com/PolyhedralDev)
projects.
## About
Seismic is a Java sampler, math, type and utility library, with a wide selection of functions and types. It started out as simply a fork of
[FastNoiseLite](https://github.com/Auburn/FastNoiseLite) that broke up the monolithic class into separate classes for
each sampler, but has since grown to include a much wider selection of samplers and features, including math functions, types, and
utilities. Where
there is overlap with Java's Math class it is assumed that Seismic's functions are faster, sometimes trading a reasonable amount of accuracy
or handling of special floating point values.
Seismic is lightweight and only depends on JetBrains' [Annotations](https://github.com/JetBrains/java-annotations)
and [SLF4J](http://www.slf4j.org/). However, it is recommended to use Seismic with a HotSpot based JDK as Seismic hooks into HotSpot's
internals for optimal performance.
