Modeling by Drawing Abstract:
Today's desktop 3D graphics technology can soundly outperform a half-million
dollar graphics workstation of five years ago. However, this revolution in 3D
performance has had only a modest
impact on people's lives. One reason is that the average person does not create
3D content -- it's too difficult with existing tools. This might explain why the
most noticeable impact of 3D graphics is entertainment: the game and movie
industries can afford to hire trained experts to painstakingly create
beautifully-detailed scenes.
Why should it be so hard to create 3D content? After all, many of us find it
easy to sketch out a rough illustration of using a pencil or chalk board. As
palmtop and tablet-PC devices are beginning to
proliferate, we should be able to use such devices to sketch out our ideas
at a coffee shop, the way we might use a napkin today. School teachers,
architects, clothing and industrial designers, and story tellers should be able
to easily create illustrations involving 3D shapes by somehow sketching with a
computer.
In this talk I will describe our own efforts and those of others to make such
applications possible. I will argue that a key enabling technology is
"non-photorealistic rendering" (NPR). This relatively new field of computer
graphics seeks to leverage principles that artists and illustrators have
developed over many centuries for conveying information. I will NPR research,
and describe some of the challenges and new directions for the field.
