I am teaching rendering, animation and visualization, but my research usually does not focus on these subjects. However, I published a sizeable number of papers about engineering visualization. I have a few posters and sketches about photo-realistic rendering. Most papers can be downloaded from my webpage.

No. 12, pp. 181-189, 2001.
(Paper)
Description: This paper presents a function-based approach
to model and animate 2D and 3D flows.
We use periodic functions to create
cyclical animations that represent 2D and 3D flows.
These periodic functions are constructed with an extremely
simple algorithm from a set of oriented lines. The speed
and orientation of the flow are described directly by
the orientation and the lengths of these oriented lines.
The resulting cyclical animations
are then obtained by
sampling the constructed periodic functions.

(Paper)
Description: Our goal in this paper is to create
user-controlled cyclical
and variable speed 2D flow animations.
Our research in implicit surface
modeling provided the theoretical framework for
introducing a new approach for animating 2D flows.
It is extremely simple to develop a system based
on the new approach. The interface to define
the flow is also very user-friendly. Based on this approach
we have implemented a system and created
various 2D flows.

(Full Paper - technical report)
Description:
We introduce hair occlusion, a general
framework that is particularly suitable for global illumination of
hair-like long, thin, and semi-transparent objects that can be
represented by a series of line segments. Our framework is
compatible with monte-carlo ray-tracing, and it can be integrated
into the final gathering stage of photon mapping. Image based
illumination techniques are also supported by this framework.

(Full Paper - technical report)
Description: We present a new approach that allows rendering
hair like structures with global illumination. We use a
projection-based method to calculate the visibility on the shading
point. Our technique is particularly suitable for hair-like long
and thin semi-transparent objects that can be approximated as a
series of line segments. In this projection method, we subdivide
the hemisphere centered on the shading point into segments that
have the same area. The result of our subdivision resembles an
igloo structure.
