pbrt-v4 is the C++ physically based ray tracing system accompanying the fourth edition of the book 'Physically Based Rendering: From Theory to Implementation'. It supports spectral rendering, modern volumetric scattering, and GPU rendering via CUDA/OptiX.

Use cases

• render photorealistic images with a physically based ray tracer
• learn how a production-quality renderer is implemented
• render scenes on NVIDIA GPUs with CUDA and OptiX
• do spectral and volumetric rendering research
• teach a computer graphics rendering course
• experiment with path tracing integrators

When to choose

• you want a well-documented, academically grounded renderer tied to a free textbook
• you need spectral rendering or advanced volumetric scattering
• you have NVIDIA GPUs and want GPU-accelerated path tracing
• you are teaching or studying physically based rendering

When to avoid

• you need a production film renderer with a large artist toolchain
• you require GPU rendering on non-NVIDIA hardware
• you want a real-time game engine renderer
