Figure 10.4.
Four types of 1D piecewise cubic value+gradient noise functions: one octave
(top left); two octaves (top right); three octaves (botom left); four octaves (botom right).
Noise in Two and Three Dimensions
For two-dimensional noise, we define a function on the [0, 1] × [0, 1] unit square
with values between zero and one. Figure 10.5, from the
noisegraph
applica-
tion, shows this in pseudocolor. You can see the same kind of differences in
Figure 10.5.
Two dimensional noise as pseudocolor; one octave (left) and four octaves (right).
