Figure 1 shows a vision of the future from the 1939 World's Fair. The human-machine interface that was envisioned is wonderful. Both machines are equipped with cameras; the woman interacts with the machine using an intuitive gesture. That degree of ...

Computer vision techniques have become increasingly important in visual effects. When a digital artist inserts an effect into a live-action scene, the more information that they know about the scene, the better. In visual effects, we use vision ...

Over the past decade, the Visual Modeling Research Program at the University of Toronto has consistently championed the concerted exploration of computer graphics and computer vision. Our premise has been this: graphics, the forward/synthesis/models-to-...

Each year, we see a growing number of 3D range scanning products on the SIGGRAPH exhibition floor. You may find yourself asking "how do these technologies work?" and "how can I make use of the shape data they produce?" In this article, I will describe a ...

This paper describes a possible approach to teaching computational geometry to students. It gives a brief introduction in computational geometry, followed by three ways of treating the area: mathematically, algorithmically and application-oriented. Next ...

Many computer graphics programmers are working in the area of scientific visualization. One of the most interesting and fast-growing areas in scientific visualization is volume visualization. Volume visualization systems are used to create high-quality ...

This paper reports on a funded project to develop a conceptual model for an engineering graphics curriculum. The analysis lead to a framework that defined the body of knowledge appropriate for engineering graphics and and a model useful for ...

Smoothly blended articulated models are often difficult to construct using current techniques. Our solution in this paper is to extend the surfaces introduced by Blinn [Blinn 1982] by using three-dimensional convolution with skeletons composed of ...

A shading language provides a means to extend the shading and lighting formulae used by a rendering system. This paper discusses the design of a new shading language based on previous work of Cook and Perlin. This language has various types of shaders ...

We propose a new rendering technique that produces 3-D images with enhanced visual comprehensibility. Shape features can be readily understood if certain geometric properties are enhanced. To achieve this, we develop drawing algorithms for ...
