The NVIDIA OptiX Toolkit (OTK) is a BSD 3‑clause licensed collection of utilities that provides unified, minimal‑macro error checking across OptiX, CUDA runtime, and CUDA driver APIs, generating diagnostic messages with source location and human‑readable descriptions. It also offers device‑side debug printing through the DebugLocation mechanism, enabling targeted one‑shot dumps, visual markers, and UI integration (e.g., ImGui) as demonstrated in the DemandPbrtScene example. These facilities streamline debugging of GPU ray‑tracing applications by catching invalid arguments, visualizing errors, and exposing GPU‑side issues that are otherwise difficult to diagnose.
