WebGL demonstrator of my procedural model for simulating pupillary hippus.
This model was published in a paper at Eurographics 2009, and it produces interesting dynamic effects for glare simulation.
The webpage includes a Matlab implementation of the model.

There has been much discussion and many misunderstandings about the work of the remarkable Danish scientist Ludvig Lorenz (1821-1891) on the theory of light scattering of a plane wave by a spherical particle. This theory is often referred to as Mie theory. In "The Scattering of Light and other electromagnetic radiation", Academic Press, 1969, Kerker presents a historical investigation of the origins of the theory and concludes:
It is not the intention of this author to arbitrate the questions of priority raised here nor to identify the theory of scattering by a sphere with any one man's name. Indeed, coincident and consecutive discoveries are common occurrences in science. But certainly if this theory is to be associated with the name or names of individuals, at least that of Lorenz, in whose paper are to be found the practical formulas so commonly used today, should not be omitted.
Nevertheless, some authors prefer to call it Mie theory rather than Lorenz-Mie theory. Perhaps because of the widespread supposition that Lorenz's theory relies on the existence of an ether. Reading the first pages of Lorenz's article, it is clear that this is certainly not true (see the translation below). Lorenz explicitly states that light propagation is like the laws for transmission of electricity and elastic forces, although it differs from the theory of elasticity in ruling out the possibility of longitudinal oscillations. Lorenz is thus working with transversal waves just like Maxwell and Mie. To uphold the recommendation that the theory of scattering of a plane wave by a spherical particle should continue to be called Lorenz-Mie theory, I decided to work on a translation of Lorenz's pioneering article from 1890.
My time available for working on this project has been very limited, and the project was on hold from 2011 to 2018. Helge Kragh then stepped in to revive the project and help complete it. This led to significant progress, so that there is now a complete first draft of the translation. The original article is:
Lorenz, L. Lysbevægelser i og uden for en af plane Lysbølger belyst Kugle. Det kongelige danske Videnskabernes Selskabs Skrifter, 6. Række, naturvidenskabelig og mathematisk Afdeling VI. 1-62. 1890. [lowres pdf]
The original article is 62 pages (one blank). The translation follows the original page numbering, and the pdf is available for download here:
Lorenz, L. Light propagation in and outside a sphere illuminated by plane waves of light. Det kongelige danske Videnskabernes Selskabs Skrifter 6(6), pp. 1-62. 1890. Translated by Jeppe Revall Frisvad and Helge Kragh, 2019.
In an old Danish Biographical Encyclopedia, the following interesting paragraph about this article appears. Translated from Danish:
Lorenz's work on the Theory of Colour Dispersion (Videnskab. Selsk. Skrifter 6. R. II, 1883) is particularly important as it is the outset of his solution of the old famous rainbow problem. The outlines of the rainbow theory are given by Descartes and Newton, more completely by Airy, who explained the supernumerary arcs by light interference. But, while one had previously limited oneself significantly to determining the directions in which these arcs appear, Lorenz set himself the goal to determine the light intensity completely in all directions on the basis of the theory of light. To complete this task, Lorenz worked almost continuously for several years; the dissertation is available in Videnskab. Selsk. Skrifter 6. R. VI (1890).
Our translation of Lorenz paper was published in European Physical Journal H together with an accompanying article describing the context and contents of Lorenz's work and surveying how it has been cited and used after its publication:
