要旨:
A long sought goal in computer graphics is to create images as realistically as
possible but at the same time as quickly as possible. Many problems have to be
solved in order to achieve this goal. This dissertation focuses on solving one
of
the main problems in real-time image synthesis: realistic shading of objects
with
complex optical material properties.
To this end, we develop a set of new techniques and algorithms using graphics
hardware. These algorithms achieve results in real-time, which are of comparable
quality to offline rendering and were previously considered impossible to
achieve
in real-time. In particular, we propose new algorithms for bump mapping and
shadowing in bump maps, several techniques for glossy reflections using
environment
maps, self-shadowing and interreflections for environment mapped objects,
as well as displacement mapping.
