## What it is
LuxCoreRender is a physically based, unbiased rendering engine with a C++ and Python API (LuxCore), supporting CPU, OpenCL, CUDA, and OptiX rendering. The repository contains the engine source, the API library, and example applications like LuxCoreUI and luxcoreconsole.

## Use cases
- render photorealistic images with physically accurate light transport
- integrate an unbiased path tracer into a C++ or Python application
- GPU-accelerated ray tracing with CUDA or OptiX
- render architectural or product visualization scenes
- bidirectional path tracing for hard light transport effects

## When to choose
- you need physically correct, unbiased rendering rather than fast approximate rendering
- you want a programmable rendering API (C++/Python) to embed in your pipeline
- you need GPU rendering via OpenCL, CUDA, or OptiX

## When to avoid
- you need real-time interactive rendering speeds
- you want a full DCC/animation suite rather than a rendering engine
- your project requires a permissive license for closed-source use without Apache-2.0 terms
