~/imallett (Ian Mallett)

Research Interests

My research interests include real-time rendering/graphics algorithms, including applications of general-purpose compute to rendering, the mathematics of light transport, and theory and algorithms associated with various graphics problems.

Selected Publications

This is a mostly complete list. Several more projects are in-production, and some ancient non-CS projects have been omitted to keep this page relevant. Sorted roughly from recent (top) to older (bottom).

I added links to my co-authors' websites , ORCIDs , and ACM IDs , when they have them, though only if I can determine them unambiguously. I have unfortunately not been able to do this in all cases, but I'd be more than happy to make updates.

Approximate Construction of Regular Polygons


Ian Mallett ,  
Brenda Mallett ,  
Russell Mallett
Published as an article in California Mathematics Council ComMuniCator (Vol 33, No. 2, Dec. 2008, pg. 35–37).
A poster version (“Fraction of the Radius”: A General Method for the Approximate Construction of Regular Polygons) was also created and presented somewhere (most likely a CMC meetup; if you know, let me know). I have subsequently heavily revised and presented this work on this subsite.

Research Bio

I used to work as an undergraduate researcher under the advisement of Dr. Pradeep Sen in the Advanced Graphics Laboratory (AGL) at the University of New Mexico (UNM). Around Fall-2012-ish, Sen left for UCSB and left the AGL in charge of Dr. Joe Kniss, who was shortly hired by perhaps Google. Kniss disappeared late fall 2013 (no one at UNM I talked to has succeeding in contacting him). I did work from fall 2013 until my graduation under the advisement of Dr. Lance Williams, though working essentially independently. After I was graduated, I went to the University of Utah as a Ph.D student where I now work under the advisement of Dr. Cem Yuksel (I am also somewhat co-advised by Dr. Erik Brunvand). I am a member of the Utah Graphics Lab and (somewhat peripherally) the Utah Hardware Raytracing Group. I also did an internship at NVIDIA Research.
