This post introduces the NVIDIA OptiX Toolkit (OTK) as a debugging utility for OptiX ray tracing applications. It details two key features: consistent error checking across OptiX, CUDA runtime, and CUDA driver APIs using macros like `OTK_ERROR_CHECK`, and targeted device-side debug printing via the `DebugLocation` structure and `debugInfoDump` function. The OTK aims to simplify the debugging process by providing detailed diagnostic messages and allowing developers to selectively output debug information from within GPU kernels.
