Mirror of Small physics engine for video games as part of a UQAC project

Project description

This project aims to simulate basic physics principles. This first part is about simple particles' behaviors, and you will be able to shoot three types of particles with their specific attributes, and see their evolution in space.

Build Guide

Download the latest version of the project

Go to your build dir and compile the source using the root CMakeLists.txt

User Guide

Once the project is compiled, you will be able to run the executable named mainPhase4. The previous apps are still working.

Selecting the parameters

Once the executable is started, you will see a window called "Parameters". Open it and expand it to see all the parameters.

Here, you will be able to choose :

• the car's linear velocity
• the car's angular velocity (rotation)
• several presets that will place a the plan's normal and the previous car parameters

If you modify these parameters, you have to click on "Apply changes" before running the simulation to see the changes. Except for the presets, these automatically Apply the changes.

If you want to apply gravity to the car, you have to click on "Apply gravity" before running the simulation.

Starting the simulation

Under the parameters section, you should see two buttons :

• Run simulation
• Pause simulation

You should click on "Run simulation" once you have all the appropriate settings. This will make the car move (except if you did not choose a linear velocity, and did not apply the gravity force). Once the car overlaps the plan, the simulation will automatically pause, meaning that the collision was detected. Sorry for not having implemented a Restart Button, you will have to close and restart the app to test the other presets.

Notes

The only plan that is visible is the one with the normal (0, 1, 0) and the offset 0. For now, we did not have time to make a corresponding mesh that would move and rotate according to the normal and the offset. Meaning that if you use the presets 2, 3 or 4, the visible plan in the scene is not the actual plan the physics engine is considering.
