PhysiXLab is a Mechanical Lab where you can test Objects interactions Based on the Book "Physics Engine Development"

used XNA as a Graphics tool / Mathematics tool (Vectors,Matrices ...)

Features

Collisions .
Adding Forces by Extneding Class Field ,Constraint or the base Effect.
Adding Impulse Generators by Extendign ImpulseGenerator
Provided Some Predefined Effects (Gravity, Spring, )

Basic Usage as a Physics Engine

void Initialize() {
	Sphere b1 = new Sphere(2.5f); // initiating & setting radius
	Sphere b2 = new Sphere(5);
	Box box	  = new Box(new Vector3(3,3,3)); // setting halfSize
	ContactGenerator cg = new ContactGenerator(); // collision detection + resolution
	cg.AddBody(b1);
	cg.AddBody(b2);
	cg.AddBody(box);
}

void Update(GameTime gameTime)
{
	float duration = gameTime.ElapsedGameTime.Milliseconds / 1000f;
	b1.Update(duration);
	b2.Update(duration);
	cg.Update(duration);
}

void Draw(GameTime gameTime)
{
	// your draw logic
}
