cosmosEngine is a lightweight 3D rendering engine built from scratch using OpenGL — designed as a modular, simulation-ready sandbox for learning real-time graphics, shader programming, and procedural geometry.
Named this way because I/we like space 🚀
This project serves as a personal playground to explore:
- Real-time rendering pipelines
- Physically based shading and cubemaps
- Interactive scene design and UI tools
- Procedural mesh generation
- Custom 3D engine architecture
Whether for reflective objects, dynamic environments, or eventually full-on simulations — this engine is built to be flexible, clean, and fun to experiment with.
- 🎮 Real-time object rendering with free-fly camera
- 🧱 Support for
.objmeshes and procedural UV spheres - 🌌 Skybox & cubemap environment reflections
- 🖼️ Reflective surface shaders (GLSL)
- 📐 Scene-based architecture (
MainScene,SecondScene, etc.) - 🧰 Modular OpenGL wrappers (
Shader,Mesh,Material,Renderer) - 🎛️ UI tools powered by ImGui
- 📦 Texture & shader management system
- 🔬 Build educational visualizations (e.g. orbit simulation, ray tracing)
- 🧪 Test procedural generation (meshes, materials, entire scenes)
- 🧩 Design for modularity — reusable renderer, materials, scenes
- ⚙️ Eventually support real-time physics and raytracing extensions
- OpenGL (core profile)
- C++17
- ImGui
- stb_image
- tinyobjloader
- Physically based materials (roughness, metallic)
- Real-time shadows
- Scene editor tools
- glTF support
- Interactive visualizations (gravity, field lines)
Feel free to clone and play around — or just use it as a reference for building your own OpenGL engine!
