Subsystems:

-Game Object Hierarcy: Game Objects can have childs which inheritate their transformations.

-Components: Each Game Object can have certain components such as transform, mesh, particle emitters…

-Own Binary Format: In order to speed up the document loading process, the engine converts .fbx files into its own format.

-Camera management: The camera has an invisible frustum that checks which objects are in the field of view of the camera so that the engine can avoid drawing unnecessary gemoetry.

-QuadTree: QuadTree checks where static elements are placed and organizes them in a way we can know if they are irrelevant for some calculations, speeding up a lot of iteration processes.

-Scene Serialization: The engine converts the scene parameters into .json files.

-Mouse Picking: Mouse Picking allows the user to select objects in the scene.

-Time Manager: The time manager is used to check how logic would look in-game, and test it by increasing or decreasing the logical time.

-Resource Manager: Keeps track of all the used files and loads and unloads the data from the files.

-Guizmo: Gizmo can be used to transform 3D elements (their position, scale and rotation).

Particle System:

The particle system is a part of the engine that allows the creation of 2D elements in a 3D enviroment. This system its divided in two parts:

-Billboarding: The billboards are plane components that always face the camera, these planes are used when the geometry is too complex and requires too much time to render.

-Particle & Particle Emitter: The particles are elements that manage the behaviour of a billboard, and the particle emitter is the compoenent that spawns them.

-Particle Customization: There is a set of parameters with which users are able to modify the behavior of the particles spawned by the emitter. They can modify the size, color, direction, speed…
