renderli

Renderli is a hypothetical open-source rendering framework designed to demonstrate the principles of modern real-time graphics engines. It targets cross-platform development for games, simulations, and visualization tools, offering a unified API that abstracts underlying graphics backends while retaining access to low-level rendering features.

Core features include a declarative scene graph, a node-based material system, physically based rendering, and a post-processing pipeline. The framework supports multiple backends (such as Vulkan, DirectX, Metal, and OpenGL) through an abstract renderer API, enabling applications to run on desktop, mobile, and embedded devices. It also provides instancing, GPU-driven culling, and a basic volumetrics/post-processing toolkit.

The architecture emphasizes modularity. Key components are the scene graph, resource manager, renderer backends, shader graph, animation system, and a lightweight UI layer. A plugin system allows additional importers, effects, and backends to be integrated with minimal changes to application code.

Usage typically involves describing scenes in a data format (JSON or YAML) or via a scripting layer, then loading assets, compiling shaders, and issuing draw calls through the renderer API. The engine aims for fast startup, streaming assets, and efficient memory management.

As a conceptual description, Renderli has no official releases or adoption metrics. It illustrates how real-world engines balance portability, performance, and developer ergonomics, and it mirrors design patterns commonly found in contemporary rendering frameworks.
