Summary
👤
Senior🎓
Top SchoolDave Demarle is a software developer specializing in high-performance rendering, scientific visualization, and ray tracing with over a decade of experience delivering production-grade imaging systems. He led the modernization and deployment of rendering software for Aurora, Argonne National Lab’s exascale system while at Intel, and has deep open-source experience contributing backend improvements to ParaView and the OSPRay renderer. His background spans hardware interfaces to application layers, enabling practical solutions for HPC visualization, baggage scanning volume rendering, and real-time gameplay systems in Unreal Engine. A former principal engineer at Kitware with teaching experience and unfinished PhD work at the University of Utah, he combines research-oriented depth with hands-on delivery across industry and academia. Notably, he has practical MPI cluster testing and temporal-caching expertise that bridge visualization algorithm design and large-scale system reliability.

An Open, Scalable, Portable, Ray Tracing Based Rendering Engine for High-Fidelity Visualization
Role in this project:
Back-end Developer
Back-end DeveloperContributions:33 commits, 7 PRs, 40 comments in 1 year 6 months
Contributions summary:Dave contributed to the `ospray` project by implementing features related to material properties such as specular color and exponent storage. They also added functionality to enable/disable shadows within the rendering pipeline. Furthermore, the user worked on setting up a cluster for testing MPI aspects of the rendering engine. The user also refactored the existing code by unifying the existing C++ tutorials by using the `rkcommon`'s `writePPM`.
