The Geometries are the basic surfaces of the models. An OBJ file basically contains a list of 'vertices', which show where each point of the model should go in 3D space, and a list of 'facets', which show how to form surfaces from those points. Here's the OBJ file for a simple cube.. v 0 0 0 v 0.02 0 0 v 0.02 0.02 0 v 0 0.02 0 v 0 0 -0.0199126 v 0.02 0 -0.0199126 v 0.02 0.02 -0.0199126 v 0 0.02 -0.0199126 f 1 5 6 2 f 2 6 7 3 f 3 7 8 4 f 4 8 5 1 f 8 7 6 5 f 1 2 3 4 You can see that each of the 'v' (vertex) lines gives an X,Y,Z location. The first 'f' (facet) line tells Poser to create a surface with vertices 1,5,6, and 2 as its corners. Poser then takes these basic instructions and does lots of other things with them: scales the shape up or down, rotates it in various ways, attaches it to other shapes to make a body, applies colors or materials to the facets. Those other actions are contained in the CR2 (figure) or PP2 (prop) files. Note that most of these files are in compressed form (OBZ instead of OBJ) in Poser 6; you'll have to unzip them to see the "real stuff".
