Timeline

  • preliminary session: t.b.a.

Contents

A simple game physics engine is developed in this lab. Starting with simple time steps for moving rigid body objects you will successively extend your developments by collision detection, rotations, friction, etc. to obtain a game physics engine.

Topics covered in this lab:

  • Introduction to game engines (Visualization, physics, scripting, ...)
  • Game-Physics (Force, momentum, torque, ...)
  • Game-Math (Numerical approximations, accuracy, time-steps, ...)
  • Modelling of springs, Ropes
  • Collision detection
  • Resolving of interpenetrations
  • Friction
  • ...

Prerequisites

  • Preliminary knowledge in C++ is advantageous, but it's no prerequisite. However, you should have experiences in object-oriented programming - e.g. Java programming.
  • No prior knowledge about visualization is necessary: A framework for visualization, interactivity and the interface for the physics is given. Thus you'll only have to implement the physics part.
  • Also no prior knowledge about physics is necessary. We'll give a short introduction to physics.

Material

t.b.a.


Recommended Literature

  • Game Physics Engine Development, Ian Millington
  • Real-Time Collision Detection, Christer Ericson
  • Game Physics, David E. Eberly


SBND Engine

The following keysettings are preset by our engine. The keys which are for debugging should be the most important for you to hunt bugs ;-)

  • Default mode:
Key Function
[a] Go left
[s] Go back
[w] Go forward
[d] Go right
[g/G] activate/deactivate gravity
[space] Switch between '1st person mode' and 'free mouse mode'
[1]-[0], [F1]-[F12] Switch to other scene and reset
[r] Total reset
[e] Reset objects only
  • Debug mode:

You can use this mode to get some information about objects. An output is created for object which is currently under the mouse cursor.

Key Function
[backspace] Activate/Deactivate Debug mode
[mouse wheel up],[+] Go one timestep forward + record current state
[mouse wheel down],[-] Go one timestep back (restore recorded state)
