This is the most basic of the input/output data formats supported by Vision3D.
It provides all the geometric and colour information necessary to
define an object. Note: in Vision3D the basic geometry consists of points
(nv = 1), lines (nv = 2), and 3 or 4 vertex planar facets (nv = 3 or 4).

Each object is defined as shown
below

nv id rd rs rg x y z x y z x y z r g b

where nv is the number of vertices, not to exceed 10 integer id is the object id, for grouping purposes integer rd is the diffuse reflection coefficient float rs is the specular reflection coefficient float rg is the gloss factor, form 2 to 100 float x y z are the coordinates of the vertices float the number depends on nv r g b is the red green blue colour component float Range from 0 to 1 for each componentFor example: to define a green square based pyramid.
