Truss Physics is a Unity3D extension package. Its purpose is the soft-body simulation. The soft bodies in Truss Physics are represented by mass-spring systems with optional internal pressure which allows simulation of a wide range of materials from jelly-like and springy to almost rigid but deformable. The simulation is done on CPU with extensive usage of SIMD and muli-threading optimizations.
Truss Physics is distributed as a single .unitypackage file. To import the package into your project use Assets>Import Package>Custom Package… menu command, browse to the folder you have downloaded the package to, select TrussPhysics.unitypackage file and click Open button. In Importing package dialog you can optionally uncheck Truss Physics Demos folder if you want to import Truss Physics without the sample scenes.
Truss Physics package will place its content in following folders of your project.
Assets/Plugins
This special folder gets the Truss Physics native plugins. Each native plugin contains Truss Physics Engine, which is the core of the simulation, bulit for a specific platform.
Assets/Truss Physics
All the integration code goes here. All game object components, asset types and custom inspectors classes are placed inside this folder.
Assets/Truss Physics Demos
And here you will find all the samples showing the Truss Physics features.
