Override3D is a 3D rendering engine I'm in the process of creating, as of now it simply exists as a decent enough foundation and boilerplate (That being said, this is a hobby project for my own experimentation and learning, the implementation is really naive but I'm pretty proud of it). Gradually, it would become my sandbox of sorts to implement and experiment with more advanced graphical techniques, such as PBR, volumetrics etc.
This engine is being made using OpenGL and C++. A common theme in Override's codebase is the abundance of inheritance and virtualisation, so as to allow room for expansion, modifcation and specialised objects. Initially, I had planned to have a bunch of interfaces which would provide a common template for every single class in the engine, but that proved to be superfluous and cumbersome. Instead I went the regular inheritance route, having 'C' objects (aka C-OMMON OBJECTS : CVertexBuffer, CMesh, CMaterial, CRenderable and so on.) that would contain alot of the resuable and vital code. We can now derive from these classes and create specialty objects to suit our needs : [AVertexBuffer (Animated Vertex Buffer), UIRenderable (A renderable that is used exclusively as a UI flat quad) and so on.]
In its current state, the default shaders are pretty limited, mostly due to the fact that I haven't really focused my energy on the GPU side as of now, instead focusing on creating a sensible structure, which I would be able to add on top of, as I learn further.
- Flexible rendering pipeline, the Renderer class draws "Renderables", containers that have a Mesh, Material and a Transform.
- The Mesh component must be provided a vector of "Vertex" objects , (a struct that defines a single vertex, consists of : Position, Normal and TexCoords). The Material class can be provided with textures, shaders, etc.The Textures can also be configured (filtering, mipmapping etc)
- Capable of loading various model types (OBJ, GLTF, ETC) using Assimp.
- Simple Parenting system using Transforms
- Simple Scene System
- Adding light nodes, and lighting (along with better shaders)
- Blending and transparency
- Re-writing the Model Loader to be more reliable
