##This extension draws 3d objects from a Wavefront .obj 3D file stored in a local folder
##Many settings for appearance, lighting, rotation, etc are available.

#Vertices are given as "v" followed by three numbers (x,y,z).
#All files need a vertex list
#v  x.xxx   y.yyy   z.zzz

#Faces are given by a list of vertices
#(vertex 1 is the first in the list above, 2 the second, etc):
#f  1   2   3

#Edges are given by a list of vertices. These will be broken down
#into adjacent pairs automatically.
#l  1   2   3

#Faces are rendered according to the painter's algorithm and perhaps
#back-face culling, if selected. The parameter to sort the faces by
#is user-selectable between max, min and average z-value of the vertices
