Graphics
For the first graphics project we had to dynamically load a scene from an external file (and be able to save to it). I decided to use JSON as my external file format because I am already familiar with a library which because I used it on a personal project earlier this year.
In the video I demonstrate the ability to move a camera in the scene with Mouse+Keyboard (WASD) and also to be able to move individual objects and lights.
Physics
For the physics project we had to do at a minimum dynamic spheres colliding with a static mesh.
In the video I demonstrate the physics engine with:
– Sphere to Sphere
– Sphere to AABB
– Sphere to Mesh
All dynamic collisions, meaning I can move any other sphere, AABB or mesh object and the collisions will be handled correctly for their new position/scale/rotation.
The majority of the collision detection is from textbook Real-Time Collision Detection by Christer Ericson
Patterns
For the patterns project we had to show use of the following patterns in our engine:
– Abstract Factory
– Builder
– Mediator
– Singleton
– Pointer to Implementation
In the video I demonstrate these patterns, and then how it is possible to add new objects to the game without making drastic changes to the code, using interfaces and messages.
