This project is a simulation of an Orrery. The purpose of this project was to develop and use maths functions and vector movement and rotation as opposed to using Unity's built-in functions. As such this project requires the creation of a small makeshift "maths library" built from scratch. All movements such as orbits, axial tilt and spin, child-parent relationships etc are achieved using these functions and vector/matrix maths, instead of "transform.translate" functions or by simply assigning child objects in the heirarchy etc. All objects are also created through code by creating meshes which are then manipulated by the matrices.
