NanoRT is a single-header, portable C++ ray tracing kernel providing BVH construction and robust ray/geometry intersection. It serves as an embeddable CPU ray tracing engine suitable for renderers, collision detection, and GPU BVH traversal.

Use cases

• add ray tracing to a C++ application with a single header
• build a path tracer or light transport algorithm testbed
• do ray casting for collision detection
• build a BVH for GPU ray traversal
• render 3D scenes on systems without a GPU
• scientific visualization with double precision ray tracing

When to choose

• you need a lightweight, dependency-free ray tracing kernel in C++
• you want portable rendering across desktop, mobile, and embedded platforms like Raspberry Pi
• you need a reference CPU renderer for developing rendering or shader algorithms
• you need a pointer-free BVH structure suitable for GPU traversal

When to avoid

• you need a full production renderer with materials, lighting, and scene management
• you want GPU-native ray tracing like OptiX, DXR, or Vulkan RT
• you need a high-level scene graph or asset pipeline
• your project is not C/C++
