Nielson's paper "The side-vertex method for interpolating in triangles" published in 1979 is amongst the top 20 most highly cited papers of the Journal of Approximation Theory, which has been in publication for over 40 years with more than 3500 papers published.

Nielson's paper with his student, Bernd Hamann, "The asymptotic decider: resolving the ambiguity in marching cubes" published in 1991, is the overall 3rd most highly cited paper of the IEEE Visualization Conference Series which began in 1990.  Nielson has said that he thinks this is one of his most clever and useful ideas for volume visualization!

Nielson's paper "On Marching Cubes" which appeared in IEEE Transactions on Visualization and Computer Graphics in 2003 is among the top 20 most highly cited papers for this journal over the past 10 years.

Nielson's paper "Multivariate smoothing and interpolating splines" SIAM Journal of Numerical Analysis 1974 was published nearly 40 years ago, yet they it continues to be currently cited.

One of Nielson's most notable (and maybe the most innovative) paper was never published as a refereed journal article.  This is the TR 40 technical report of the Mathematics Department at ASU "Some piecewise polynomical alterrnatives to splines under tension".  It has been continuously cited every year since it was written in the early 70s (nearly half a century ago!)  Extremely few research papers have this longevity or influence!  These curves (which are sometimes referred to as nu-splines) exploided for design purposes a disconnect between the continuity and smoothness properties of the graphs of component functions and the graphs of the resulting parametric curves.  Parmetric curves with component functions which have very smooth graphs (no corners e. g.) can conveniently lead to parametric curve graphs with sharp features!  (E. g. corners, Go figure! How can this happen??? Rather amazing and very useful!)  This feature allows these curves and surfaces to be used for modeling buildings and other artifacts.   If you are interested and can't easily find a copy, please contact: nielson@asu.edu

It is one thing to have citations to your research but a whole different level of recognition is to have your research referred to in the title of a research publication.  Some examples are:
