In the past few years hardware rendering has made significant progress
from simple Gouraud-shaded polygons with per-vertex illumination towards
more sophisticated and realistic shading and lighting effects. Based on
multi-pass and multi-texture algorithms, we can now achieve a variety
of interesting effects such as shadows, local illumination with complex
materials and light sources, a variety of global effects, as well as rendering
of participating media.
To deal with an ever increasing demand of more and more complex effects,
hardware vendors have recently begun to extend the traditional rendering
pipeline with additional features. On the one hand, this serves to increase
the number of operations that can be performed with the hardware, and
to improve the performance of algorithms by reducing the number of rendering
passes. On the other hand, these new extensions are often available only
on specific graphics chips, and they are hard to program for.
Very recently, several research groups have started working on shading
languages for graphics hardware with the goal to hide the hardware differences
and to simplify the programming task. While this is an exciting area,
the current approaches still face a number of problems. For example, it
is unclear which feature set should be provided by the language, or to
what degree hardware restrictions should be hidden or exposed. The compiler
technology is currently the most fragile part of realtime shading systems.
It could benefit greatly from orthogonal hardware feature sets, precise
models for performance and precision of given multi-pass algorithms, as
well as hardware support for avoiding the "brick wall effect" when an
algorithm exceeds certain limits of hardware resources.
In this talk we review the progress that has recently been made in hardware
rendering. We then discuss the open problems and challenges that we still
face both on the hardware and on the software side.
