Integration is used to determine the motion of an object over time. In this article I show how to integrate the equations of motion using an RK4 integrator.
Even an RK4 integrator is sensitive to the amount of time you step when integrating. Decouple your physics timestep from the display framerate so that your simulation behaves exactly the same way each time it is run.
Leap ahead from integrating single values to integrating the entire physics state for a cube in three dimensions. Introduces rotational physics concepts including orientation in 3D, angular velocity and momentum, inertia and torque.
Explains the physics of springs and how to apply them to control physics simulations. Learn how to implement joints, constraints, motors and basic collision response.
How do network games synchronize physics over the network? This article explains the core techniques used in today’s first person shooters and shows how you can apply these techniques to network your own physics simulation.
