A structure model for volume rendering, called a shell, is introduced. Roughly, a shell consists of a set of voxels in the vicinity of the structure boundary together with a number of attributes associated with the voxels in this set. By carefully choosing the attributes and storing the shell in a special data structure that allows random access to the

Spray rendering provides a framework for creating and experimenting with different visualization techniques. The name spray rendering is derived from the metaphor of using a virtual spray can to paint data sets. Varying the type of paint in the can highlights data in different ways. Spray rendering is not limited to the paint metaphor, however.

Interruptible rendering is a novel approach to the fidelity-versus-performance tradeoff ubiquitous in real-time rendering. Interruptible rendering unifies spatial error, caused by rendering coarse approximations for speed, and temporal error, caused by the delay imposed by rendering, into a single image-space error metric. The heart of this approach is

Abstract Previous studies at the intersection between rendering and psychology have concentrated on issues such as realismand acuity. Although such results have been useful in informing development of realistic rendering techniques,studies have shown that the interpretation of images is influenced by factors that have little to do with realism.

The animated short "a flatpack project" was intended to emulate the aesthetics of traditional art techniques in a digital medium. This necessitated the creation of custom rendering and image processing code to reproduce the appearance of line drawings in both pencil and ink, along with other effects such as the bleeding of ink in water and the ...

Volumetric rendering speaks volumes for data 20 orders of magnitude apart—from human anatomy to neuroanatomy, and from electrostatic charges of macromolecules to failure analysis of manufactured parts.

A mathematical semantics of rendering I: Ideal Rendering
Computer Vision, Graphics, and Image Processing, 1989Abstract The diversity of ways in which scenes can be mapped into raster images necessitates an examination into precisely what is meant by the process of rendering . The development of 3D graphics standards and graphical programming languages requires the ability to specify, evaluate, and rigorously prove properties of renderings.

Despite the relative sophistication of modern surface design systems, many graphical renderings of surfaces are rather crude. The paper discusses several possible renderings, including various line drawings methods, realistic and functional shading, and combinations of line drawings and smooth shading.

We present an integral equation which generalizes a variety of known rendering algorithms. In the course of discussing a monte carlo solution we also present a new form of variance reduction, called Hierarchical sampling and give a number of elaborations shows that it may be an efficient new technique for a wide variety of monte carlo procedures.
