Creating software tools for Unreal Engine and visual programming. Check out the UEToolbox plugin.

Started various Unreal Engine projects including UE Modeling Mode, Geometry Scripting, Scriptable Tools, the GeometryProcessing Plugin / GeometryCore library, and the Interactive Tools Framework. Applied geometry magic to Fortnite, LEGO Fortnite, the Matrix Awakens demo, Metahumans, and the Lyra sample game.

Previously: Principal Scientist (2020-2021), Team Lead - Geometry Editing (2018-2020).

Geometry Processing. 3D Printing. 3D Design Tool Consulting.

Department of Computer Science. Participating in PhD candidate committees, course lecturing, general advisory this-and-that.

Senior Principal Research Scientist in Autodesk Research. Worked on Interactive 3D Design, 3D Printing, Rapid Prototyping / Personal Fabrication, geometry processing, sketching interfaces. Designed / Developed / Managed the Meshmixer product (1m+ downloads). Introduced core mesh processing infrastructure that powered parts of Netfabb, Inventor, Mudbox, 3DS Max, and Fusion 360 Mesh Workspace, as well as many discontinued products (Remake, Spark Print Studio, Memento).

Designed and developed meshmixer, a highly interactive tool for 3D mesh sculpting, composition, repair, etc. Meshmixer software acquired by Autodesk.

Studied visual perception of line drawings, applications of metaheuristic optimization.

Research Intern (2008-2010): Automated interpretation of 3D line drawings, perceptual biases in line drawing interpretation, velocity of implicit surfaces. Papers published at SBIM 2009, SIGGRAPH ASIA 2009, and in ACM TOG 2011. Made contributions to the ViewCube component (used in nearly all Autodesk products) and Maya’s Nucleus cloth solver (mainly collision detection).

Principal Developer Consultant (2010-2011): Worked on Project Dasher. Designed and developed interactive desktop application for exploring 3D building information models (BIM) combined with real-time sensor network data visualization.

Maintained and enhanced existing 2D/3D graphics engine. Order-of-magnitude performance improvements in large model rendering framerates. Added collision/interference detection, database-backed caching, occlusion culling.
