Manta is being made solely by me. It is very much a work in progress and a lot of the code is currently based on a tutorial series save for some of the rendering code.
Currently (Feb 2021) Manta is built as a Static Library and functions as a framework that you could potentially make games in. An OpenGL 4+ renderer is being worked on and the API code is
abstracted away from the rest of the framework. My goal is to implement a rudimentary OpenGL renderer and then implement a PBR render pipeline using DirectX 12 and perhaps even support DXR.
Manta is my creative outlet and an environment for me to learn and improve my C++ and graphics programming abilities. I also work on it to improve my understanding of engine architecture. I work
on it in my spare time for fun and learning.
So far it has been extremely rewarding and educational.
