circle_bresenham()

static void circle_bresenham ( int  xc, int  yc, int  r, int  nn  )

static

An expanding circle from the fracture point is used to determine the midpoint between fractures.

The cells must be assigned to landmasses anyway.

fmfill()

static void fmfill ( int  x, int  y, int  c, int  r  )

static

Assign landmass in 3x3 area increments to avoid "holes" created by the circle algorithm.

local_ave_elevation()

static int local_ave_elevation ( struct tile *  ptile )

static

Determine the local average elevation.

Used to determine where hills and mountains are.

Fracture map generator.

make_fracture_relief()

void make_fracture_relief

(

)

make_fracture_relief() Goes through a couple of iterations.

The first iteration chooses mountains and hills based on how much the tile exceeds the elevation of the surrounding tiles. This will typically causes hills and mountains to be placed along the edges of landmasses. It can generate mountain ranges where there a differences in elevation between landmasses.
