3D Rendering
Atlas supports 3D meshes, cameras, transforms, lighting, and directional light. The engine also renders 2D UI inside 3D scenes, which is visible in the demo through the health and hunger bars.
Custom C++ / Lua Engine
3D rendering, materials, and physics built into a general-purpose engine.
Atlas is a custom game engine built with C++ and Lua. The final version focuses on an OpenGL-based 3D pipeline, script-defined materials, and Bullet-powered 3D physics.

Core Work
What this version adds
Materials
The engine supports custom materials defined from the scripting side. Different textures can be assigned to create distinct surface appearances, such as the grass and dirt materials shown in the demo.
Physics
Atlas supports 3D physics using Bullet Physics. In the test scene, physics is used for collision handling as well as player movement and traversal.
Architecture
High-level engine structure
Engine Layer
C++ handles rendering backends, asset loading, math, physics integration, and the engine runtime.
Scripting Layer
Lua drives gameplay behavior, scene logic, materials, and interaction logic on top of the engine systems.
