NVIDIA's implementation of instant neural graphics primitives, training NeRFs, signed distance functions, neural images, and neural volumes in seconds using multiresolution hash encoding on a single GPU. It ships as a desktop application with prebuilt Windows binaries and Python bindings built on the tiny-cuda-nn framework.

Use cases

• train a NeRF from photos in seconds
• reconstruct 3D scenes from images
• learn signed distance functions of 3D surfaces
• represent gigapixel images as neural networks
• render captured scenes in real time
• denoise volumetric radiance fields from path tracers

When to choose

• you need extremely fast NeRF or SDF training on an NVIDIA GPU
• you want real-time rendering of neural radiance fields
• you want a reference implementation of multiresolution hash encoding
• you want prebuilt binaries to try NeRFs without building code

When to avoid

• you don't have a CUDA-capable NVIDIA GPU
• you need permissively licensed code for commercial products (research license only)
• you need CPU-only training
• you need a production 3D reconstruction pipeline rather than a research tool
