CUDA Ray Tracing

Accelerate your code 10x or more with CUDA.

Prerequisites

• NVIDIA Toolkit >= 11.4 (Check the NVIDIA website for latest installation steps)
• NVIDIA GPU with compute >= 7.5 (Verify whether your device qualifies at the cuda-gpus website)
• cmake >= 3.8

How To Run in Windows

• Set the CUDATOOLKITDIR environment variable to the location of your CUDA Toolkit.

  set CUDATOOLKITDIR=<Path\to\Toolkit\CUDA\v11.4>

• Run cmake to configure your project.

  cmake . -G "Visual Studio 16 2019" -B build -DCMAKE_BUILD_TYPE=RelWithDebInfo

  You can change to flags to set a different generator -G or a different build folder -B
• Open the generated solution in Visual Studio and compile main.exe
• Run main.exe > image.ppm to generate the following image:
