A fractal texture relies on random numbers
being applied initially over a large area but which are
reduced as the process loops and the areas get smaller.
The basic
technique is known as the diamond square
method.
The diamond square takes the corners
of a square and averages the colour
values, then applies a random variation
(up or down) within a starting range.
By this means, the centre and the
middle points of at least 2 edges are
found.
From
We calculate
When a whole block of squares is
done, the process starts again at half the
size of the previous run. The values
calculated in the previous run then become
corners of smaller squares
The random variation is lessened on
each pass..
