Brief Description of Features
Brief Description of Features
In our implementation of particle systems, the following particle systems were created:
- Bouncing balls
- Water spout simulation
- Fire simulation
- Magic spell simulation
- Snow simulation
Furthermore, these additional features are also included:
- 3D user controlled camera, allowing for both translation (WASD) and rotation (mouse movement)
- 3D implementation
- >1000 particles simulated and rendered at over 30 FPS
- Real-time user interaction with system
- Space bar- starts/stops flow
- Up/down arrow keys- increase/decrease the generation rate of the emitter
- U/I/O/P keys- changes the region the emitter samples from when generating particles to a point, disc, sphere, or rectangle, respectively
- -/+ keys- decrease/increase the size of the emitter if it is a disc, sphere, or rectangle
- 1/2/3/4/5/6 keys- switches the program to default, bouncing balls, water, fire, magic spell, or snow, respectively
These features can all be seen in the following video showcase:

Difficulties We Encountered
Difficulties We Encountered
The main difficulty we encountered in attempting a feature of this assignment was in trying to implement textured particles by drawing quads at each particle's position. In the end, we did not finish this feature, but did make progress toward it by creating a Quad class and working on getting a draw function for Quads to be operational.
Other smaller difficulties we encountered included figuring out how best to organize classes within our code to include different types and shapes of Emitters and different objects within the scene, as well as figuring out a method for making the fire particles move more realistically after spawning.
Of course, time management is always a difficulty as well, but we got as much done as we could in the time before the assignment was due and are satisfied with what we were able to complete. Additionally, we hope to find time after the due date to continue playing with our Particle Simulation!
