Abstract:
Where would computer graphics be without
cameras? To make a synthetic picture with
computer graphics, we usually imagine a camera of
some sort, taking a picture of a scene. Such cameras
range from the simplest pinhole camera to a sophisticated
simulation of optics and shutters. Usually,
though, our imaginary cameras are close analogs to
the real thing.
If we’re willing to move away from the idea of simulating
a real camera, we can explore some interesting,
alternative imaging models—such as digital Cubism. If
we’re thoughtful, we’ll be able to harness possibilities
for communicating ideas and story points in new and
expressive ways. Let’s look at some basic camera models,
then consider how we can extend them.
