nice little engine

Experimental graphics and physics engine

A heightmap terrain and procedurally positioned terrain features

Summary:

All classes will be Doxygen style commented, I avoid doing that now, because many things I did need refactoring, I don't want to document all of my mistakes :')

- Object3D: Every object in a scene (including a scene) inherits from Object3D
  │
  ├── RenderObject3D: Rendered by Renderer3D
  │   │
  │   ├── MeshInstance (see: Mesh)
  │   │   │
  │   │   ├── Sky: A skybox cube with distance fog feature.
  │   │   │
  │   │   └── TerrainInstance
  │   │
  │   └── MultiMeshInstance (see: MultiMesh) Any loaded model's instance is a MultiMeshInstance.
  │
  ├── PhysicsObject3D: Limited to have one child that being a RenderObject3D. Passed 
  │                    to the PhysicsEngine. Its child is rendered by Renderer3D.
  │
  ├── Scene: Entry point of an Object3D tree. It has a default Sky, Light and a Camera.
  │
  ├── Light: Directional light with ambient, diffuse and specular.
  │
  └── Camera: Camera implementation with free roam option.

- Renderer3D: Renders a (3D) Scene.

- PhysicsEngine: Processes registered PhysicsObject3Ds. It's so simple, not done yet.

- Shader: Shader implementation. Can be loaded from memory or file.

- Texture: Not very detailed (but working) texture implementation. Can be loaded from memory or file.

- InputHandler: Input handler class that emits signals on mouse and keyboard events. Needs improvement.

- Window: Window class implemented upon GLFW.

- Nle: Main class that initializes and destroys window, renderer, physics engine and defaults. It's essentially our main application.

TODO list by difficulties

• Hadoken
  • editor (code needs a mass refactor and cleanup)
  • gltf & glb loading
  • scene saving and loading
  • point light
  • mouse ray for 3d interaction
  • default shaders need tidying up
• Shoryuken
  • instanced drawing (that works with physics engine)
  • point light (and multiple lights)
  • shadows
  • materials need more than specular
• Tatsumaki Senpukyaku
  • collision system that does not suck
  • skeletal animation system
  • a game made with nice little engine that works
