Qu3e-Sharp

Qu3e-Sharp is a unofficial C# ported version of RandyGaul's Qu3e Physics Engine

The aim for this repository is to provide an easy library for those who need a simple physics engine that run using C# back-end. The product of this repository is a managed, portable library that independent of any reference (other than mscorlib.dll) so it can be used by many programs with C# back-ends like .NET Core, XNA, Unity, etc.

Changes

C# has different environment than C++ in many areas so it's impossible to port with 100% exact implementation. However the aim is same: Simple and efficient.

The latest version of this repository is based from the original repo version 1.01.

Changes that make this repository different than the original:

Naming convention:

• Removed all former-name 'q3' in every file, functions and classes
• All classes and structs is in a namespace 'Qu3e'
• All public variables is capitalized with PascalCase

Value types:

• Double precision is used for all 'r32' values
• Common/small classes like Vec3, Mat3, Quaternion, Transform is a struct.
• All void* values is an arbitrary Object class.
• FILE type for scene dumping is replaced with StringBuilder

Built-in Libraries & Referencing styles:

• Changed (nearly) all std math functions to System.Math
• (nearly) all arrays, including linked classes are replaced with List<T>
• Common/Settings.cs is a special static class and the rest of code is referencing it by 'using static' (C# 6.0 feature), therefore some static functions also moved there.

Caching and memory Management:

• MemoryAllocator, Page, Stacks is removed because C# is a managed language.
• All temporary arrays inside functions is moved out to prevent memory garbage.
• Island variable inside Step() in Scene is no longer be a temporary variable
• Because of frequent allocations, ContactState and ContactConstraintState has it's own memory management inside it's own class.

Additional Features

This repository does also and will made some improvement outside the original. Some features of that include:

• Variable delta time

Note that this doesn't mean I won't contribute anything back to the original. If you want to contribute, consider to do that in original repo if you can write C++.

Demo

This repository has a demo in WPF application. So far the demo doesn't implement Common/Render.cs yet.
