Computer graphics systems are capable of generating stunningly realistic images of objects
that have never physically existed. In order for computers to create these accurately detailed …

We quantify the degree of lopsidedness for a sample of 149 galaxies observed in the near-
infrared from the OSUBGS sample, and try to explain the physical origin of the observed disk …

This paper introduces a new image-based approach to capturing and modeling highly
specular, transparent, or translucent objects. We have built a system for automatically …

Weathering modeling introduces blemishes such as dirt, rust, cracks and scratches to virtual
scenery. In this paper we present a visual stimulation technique that works well for a wide …

Interesting textures form on the surfaces of objects as the result of external chemical,
mechanical, and biological agents. Simulating these textures is necessary to generate …

This paper presents a system for modeling lichens and simulating their propagation and
growth in a virtual scene. Lichens colonize almost every substrate in nature and play an …

Aging and imperfections provide important visual cues for realism. We present a novel
physically‐based approach for simulating the biological aging and decay process in fruits …

Rendering of clean transparent objects has been well studied in computer graphics.
However, real-world transparent objects are seldom clean—their surfaces have a variety of …

Weathering, referring to techniques for depicting outdoor objects as having suffered rain and
wind damage, has a long history of research, and many methods can be found in the …

The computer graphic simulation of a common spray painting artifact, called orange peel, is
discussed. Orange peel distorts surface reflections and is commonplace in product design …
