Spine is a 2D skeletal animation tool for game development and other animation projects.
Jitter Physics is a fast and lightweight physics engine written in C#.
Bonsai Physics Library containing modules for creating reactive 3D physics simulations.
Physics related type system that models the physical world, including distances, areas, etc. Includes strongly typed operators, so that multiplying two distances results in an area, etc.
The physics library extends YAMP with constants and functions that play an important role in general physics.
The sensors library extends YAMP with functions which can talk to some of the sensors that can be connected to a Windows PC. This library is required by Sumerics and cannot be disabled.
The IO library extends YAMP with functionality to interact with the filesystem.
The Sets library extends YAMP with Sets and set operations.
This fork of jitter physics targets netstandard 1.4
