Course Overview

Class Description:

This recorded class is a technical session on working with various different scientific data types in Houdini. Topics covered include data wrangling, Houdini-friendly formats like Geo/Bgeo and OpenVDB, Houdini-unfriendly but common scientific data representations like Adaptive Mesh Refinement, and spatial and temporal data interpolation. This will be an introduction to the data and programming side of Houdini, with less focus on design or rendering.


Learning Outcomes:

Students will leave with a fundamental understanding of how to incorporate real scientific data into their Houdini scenes, and with Python starter code for accomplishing a few common data transformation tasks.

Instructor

Kalina Borkiewicz

Director of Visualization @ NCSA

Kalina leads the Advanced Visualization Lab (AVL) at the National Center for Supercomputing Applications (NCSA) at the University of Illinois at Urbana-Champaign. Kalina’s background is in computer science, and she works in a “Renaissance Team” that consists of artists, scientists, and programmers. Since 2014, Kalina and the AVL have been using Houdini to create cinematic scientific visualizations of real data, captured by scientific instruments like satellites or simulated on massive supercomputers like Blue Waters. These visualizations are seen around the world in the form of planetarium fulldome shows, IMAX films, and streaming documentaries.
