Code::
+-----h-----h
|0   /|\   4|
|  /  |  \  |
|/   1|5   \|
+-----h-----h
|\   2|6   /|
|  \  |  /  |
|3   \|/   7|
+-----+-----+
seen from above 0-7 are the top faces of brushes (triangular prism with 5 faces total)
h is a pixel of the heightmap translated into a Z value
these clusters of 8 brushes repeat depending on how large the heightmap or the divisions are...
+ is the h of the neighbouring brushes
