Computer Graphics International (CGI) is co-located with Computational Aesthetics (CAe). We will share the venue and the social events. Attendees of either conference may attend the keynotes of both. CGI attendees may join in the CAe art programme.



Seeing in 3D

Level: Beginner

Most people, even technical draftsmen, designers and computer graphics programmers, find it very difficult to visualise 3D shapes well enough to reason about them. This course demonstrates the problem and takes attendees through a series of exercises that help them acquire this important practical skill.

"Stand a cube on its corner. What is the shape of a horizontal cross-section taken at half the height of this object?" About four percent of human beings can reason about 3D space well enough to answer this question easily and with confidence. Most of us enter a state of panic when confronted by 3D problems. Yet it is possible to train yourself to think and visualize in 3D. This course helps attendees start thinking in 3D. Once they have the basic principles, they can develop the skill independently.

Familiarity with some basic geometric ideas (for example, two planes meet in a straight line). Also helpful: awareness of how to find distances with Pythagoras' theorem, but this is used for only a few exercises, and the course can be understood without mathematics.

Intended Audience
Graphic artists, engineers, designers, computer graphics programmers, and students interested in graphics, drawing, or sculpture.
