 DESCRIPTION                 = "This shape file of asteroid 4197 Toutatis
was created by Scott Hudson based on radar observations and has the format 

v x1 y1 z1
v x2 y2 z2
v x3 y3 z3
(etc.)
f i1 j1 k1
f i2 j2 k2
(etc.)

where the letter 'v' denotes a vertex and the letter 'f' denotes a triangular
facet.  The VERTEX_TABLE is the first part, describing the positions of the
vertices of the shape model.  The floating point numbers x1 y1 z1 are the
coordinates of vertex 1, and so on (vertices are implicitly numbered
beginning with 1). The units are kilometers.  The linking of vertices into
facets is provided in the FACET_TABLE.  This format is identical to a
Wavefront OBJ file.  There is a freeware program called WCVT2POV that will
convert this format into other formats such as POVray and DXF.
