**Title: *** B-Splines and 3D Web Graphics: Mathematics and Technology
Behind the Visualizations of the NIST Digital Library of Mathematical Functions
*

**Abstract: **
In 2010 NIST launched the Digital Library of Mathematical Functions (DLMF)1,
a free online resource containing crucial information about high level
functions useful in mathematical and physical application areas. The NIST
DLMF replaces Abramowitz and Stegun's Handbook of Mathematical Functions,
which is believed to be one of the most cited mathematical references on record.

I will briefly look at the history of these compendiums to motivate my
discussion of research and development work in numerical grid/mesh generation
and 3D Web graphics technology used to create more than 600 function graphs
and visualizations for the DLMF. I will discuss changes made since the
original DLMF launch and describe some current research work.

I will conclude with a brief look at a DLMF spin-off project, DLMF Tables,
and describe a few opportunities for postdocs and internships at NIST.
