Name	Description
rand	Map with random heights between 0 and 1
fftGen	Spectral synthesis-based height map, whose spectrum depends on an REC: $1/(f^{\text{REC}})$
gauss	Gaussian bell shape height map, whose wideness depends on an REC
plane	Flat inclined plane height map whose orientation depends on an REC within 8 values
step	Step shape height map whose orientation depends on an REC within 4 values
sphere	Semisphere height map whose centre location is random and the radius depends on an REC
