    /** 
     Describes the visual shape and appearance of an object in a scene.
      
     The <geometry> element categorizes the declaration of geometric information. Geometry is a branch of
     mathematics that deals with the measurement, properties, and relationships of points, lines, angles,
     surfaces, and solids. The <geometry> element contains a declaration of a mesh, convex mesh, or spline.
     There are many forms of geometric description. Computer graphics hardware has been normalized,
     primarily, to accept vertex position information with varying degrees of attribution (color, normals, etc.).
     Geometric descriptions provide this vertex data with relative directness or efficiency. Some of the more
     common forms of geometry are:
     • B-Spline
     • Bézier
     • Mesh
     • NURBS
     • Patch
     This is by no means an exhaustive list. Currently, COLLADA supports only polygonal meshes and splines.
