waterman - Waterman polyhedra

Usage

Synopsis

Description

Options

lattice

Lattice can be SC, FCC, or BCC

-h

program help

-r <r,n>

clip radius. r is radius taken to optional root n (default n=1), n=2 uses the square root of r.

-q <cent>

center of lattice, in form x_val,y_val,z_val (default: origin)

-m <method>

method can be 1 - sphere-ray intersection (default), 2 - z guess

-t

disable computational error testing for sphere-ray method

-v

verbose output (on computational errors)

-y <lim>

minimum distance for unique vertex locations as exponent 1e-lim (default: 12 giving 1e-12)

-o <file>

write output to file, if this option is not used the program writes to standard output

-C <hull>

hull can be c - convex hull only (default), i - keep interior, s - supress

-V <col>

vertex colour, in form R,G,B,A (three or four values 0.0-1.0, or 0-255)

-E <col>

edge colour (if convex hull), in form R,G,B,A (three or four values 0.0-1.0, or 0-255)

-F <col>

face colour (if convex hull), s - by symmetry using indexes, S - by symmetry using values

-T <tran>

face transparency, in range 0 (invisible) to 255 (opaque)

Examples

    waterman -r 10,2 fcc | antiview

Make a Root 100 Waterman polyhedron, with symmetrically coloured faces

    waterman -r 100,2 fcc -F S | antiview

Make a Root 100 Waterman polyhedron centred on an octahedron centre, with symmetrically coloured faces

    waterman -q 0.5,0.5,0.5 -r 100,2 fcc -F S | antiview
