Physics (Q8)

Lab 1: Many Colliding Spheres

Here I implement simply sphere-sphere collision and collision resolution in my engine. Here you see (some of) hundreds of spheres that exist in the scene and collide with eachother efficiently.

Lab 2: Conservation of Momentum

Here I implement conservation of momentum in the engine, and have a demo of objects whose masses can be changed, and will speed up or slow down accordingly, to preserve their momentum.

Lab 3: Drag

Here I implement simple drag forces in my engine, causing objects to slow down depending on the specified drag coefficients.

Lab 4: Resting Contact

Here I get spheres stacking successfully by implementing resting contact in my game engine. Spheres can be knocked over by launching another sphere at them and they will bounce.

Lab 5: Spings

Here I get a working spring force, where one sphere is attached to another via an invisible spring. Closer than the specified distance and the second sphere is pushed away, further and it is pulled closer. Spring constants and resting lengths can be modified at runtime.

Lab 6: Angular Velocity

Here we work with angular velocity, and allow an object to be detached from it's parent object that it rotates with, but allow it to preserve it's angular momentum while doing so.

Extended Details

In our final game engine course, we were told to implement physics in our engines. With the engine enhancements from the AI course, my engine was ready to tackle this task.

Due to short time-constraint and tough schedule, we were not required to implement a full physics engine, simply to handle sphere physics in a few particular fun cases including bouncing, resting contact, angular momentum, drag and springs.
