Using fairly simple language, what is Hermite data? I encountered it here, http://www.frankpetterson.com/publications/dualcontour/dualcontour.pdf and could not get an answer on standard StackExchange, who 'referred' me to here.
What is Hermite data?

0I've been reading this article recently and have no clue what a hermite data is. But for this article specifically, I think the author already given a explanation for hermite data in its abstract: Hermite data (i.e; **exact intersection points and normals**) hope this would help – 2015-12-11

Hermite data is the value of a function and all its derivatives up to some order at all points of a data set. It is used in Hermite interpolation.
If you do not supply all the derivatives for all points, then you have Birkhoff data, also called Hermite–Birkhoff, which of course is used in Birkhoff interpolation.

0@ПетърПетров I am no expert on this, but since Dual Contouring focuses on rendering isosurfaces (surfaces of the form $f(x, y, z) = 0$) That you must have an algorithm that computes $f(x, y, z)$ for all $(x, y, z)$ in the domain, and you must have an algorithm that computes the derivative of $f(x, y, z)$ at every $(x, y, z)$ in the domain. – 2017-08-31
