OptiX is an application framework for achieving optimal ray tracing performance on the GPU. This repository contains the minimal set of necessary header files for building an application with OptiX support, including access to the OptiX functions provided by the NVIDIA display driver. Usage of this API allows for an application to offload its ray tracing calculations to the system's onboard NVIDIA GPU card, potentially drastically reducing render speeds. This SlackBuild targets SBo's graphics/Blender SlackBuild which will automatically detect the OptiX headers and build Blender to include OptiX rendering kernels as well as GPU-accelerated image denoising. The built OptiX-Headers package requires a recent CUDA toolkit to be useful when building Blender but the CUDA toolkit is not required to build OptiX-Headers itself.
