Cell is an open-source OpenGL graphics engine written in C++ by LearnOpenGL author Joey de Vries, designed as an educational repository showing how a larger graphics engine can be structured. It includes a custom math library, shader system with pre-processor, material pipeline, mesh/model loading via Assimp, framebuffer utilities, and a deferred rendering pipeline with PBR lighting.

Use cases

• learn how a graphics engine is structured
• study deferred rendering implementation in C++
• understand PBR lighting shaders
• see how render command buffers and state sorting work
• learn OpenGL engine architecture from commented source
• build a 3D renderer on top of an educational engine

When to choose

• you want readable, heavily commented source code for learning graphics programming
• you need a reference implementation of deferred rendering and PBR in OpenGL
• you are studying engine architecture rather than shipping a product

When to avoid

• you need a production-ready engine with stable builds and active maintenance
• you require proper build files or cross-platform build support out of the box
• you need long-term support or recent updates, as the project has been inactive since 2018
