Variable Documentation

bool Addition = TRUE

Overlay over a wadi valley?

The fractal landscape can be draped over a wadi valley.

float Grad = 15

Wadi valley slope in degrees.

This variable makes only sense when Addition == TRUE.

Definition at line 23 of file main.cpp.

float Hurst = 0.45

Surface heterogeneity (patchiness).

The Hurst factor increases the heterogeneity (patchiness) of the landscape. A standard value is 0.45.

Definition at line 15 of file main.cpp.

Referenced by main().

int Iterations = 9

The number of Iterations used for producing the landscape.

The surface becomes smoother with more iterations.The edge of the grid must have length 2ⁿ+1 with n ≤ Iterations.

bool Parabel = FALSE

The shape of the wadi.

The cross-section of the wadi valley can have either the form of a parabola or the form of a symmetrical inverted trapezoid.

int Sigma = 25

Surface variability (roughness).

Sigma increases the surface variability. A standard value is 25.
