Fast High-Quality Noise |

| Abstract | At the moment the noise functions available in a graphics
programmer's toolbox are either slow to compute or they involve
grid-line artifacts making them of lower quality. In this paper we
present a real-time noise computation with no grid-line artifacts or
other regularity problems. In other words, we put a new tool in the
box that computes fast high-quality noise. In addition to being free
of artifacts, the noise we present does not rely on tabulated data
(everything is computed on the fly) and it is easy to adjust quality
vs. quantity for the noise. The noise is based on point rendering
(like spot noise), but it extends to more than two dimensions. The
fact that it is based on point rendering makes art direction of the
noise much easier. |
