OptiX is the industry's premier ray tracing engine in terms of performance, functionality, and adoption. We will present three recent advances in OptiX. First, the renovation of the core of OptiX, including using an LLVM-based compiler pipeline, which brings several performance benefits and opens the door for long-desired new features. Second, the OptiX VCA allows OptiX-based applications to transparently use NVIDIA Visual Computing Appliance for massively parallel, shared, remote rendering. Third, we will share exciting results of our top partners and their recent successes with OptiX.
