## frac fac vol

### frac fac(f)vol(id)

Returns the fractal coefficients of facets numbered **f** of volume **id**.
### frac fac(f)vol(id)=n,cn,cx,cy,cz

Changes these coefficients.
## frac vol

### frac vol(id)

Returns the fractal coefficients of volume **id**.
### frac vol(id)=n,cn,cx,cy,cz

Changes these coefficients.
## Fractal coefficients

**n,cn,cx,cy,cz:**

**n**: depth of recursion: every facet of 4 vertices is divided into four facets and this recursively.

**cn,cx,cy,cz=randomcoefficients**

cn: according to the normal at facets.

cx: according to x axis.

cy: according to y axis.

cz: according to z axis.

Si cn=cx=cy=cz=0: flat fractal.

**Blocks generated by the fractalisation**

The following blocks are automatically generated:

**fac generate vol(id)**: facets of volume fractalised.

**poi generate vol(id)**: points of volume fractalised.

**normal vertex generate vol(id)**: normals at vertices of the volume fractalised.

near frac vol(id).

**near frac vol(id)**: points generated by fractalisation (avoiding double existing points) {(n1, n2, n12)}:

n1,n2,0: n2 is the copy of point n1 in original volume.

n1,n2,n12: is the noised midpoint of points the n1 and n2 of the volume fractalised.

**normal fac generate vol(id)**: normals at facets of the volume fractalised.
