VR Gravity Simulation
An in progress gravity simulation for use with google cardboard.
This is a work in progress of a VR gravity simulation. I hope to eventually deploy this as a free application for use in visualizing planetary orbit. It currently functions in a google cardboard headset and allows the user to spawn in planets at their discretion and clear the board by triggering the red object at the top. I am in the process of adding the additional functionality of letting the user draw initial vectors for new planets in both a 2D and 3D environment, adjust the mass of the planet and creating a better user interface. I am also working on new art assets for the game as most objects are primitive shapes.
There is a great community for development in Unity and I have utilized many online resources to accomplish what I specifically want. I will share the manager script (in C#) for the game that generates new planets based on user input. The script is still in progress as I hope to better implement what I have and implement the previously stated functionality.
