## Documentation

> Statistics base class. Used to extract primitive information from the renderBin(s). Add a case of getStats(osgUtil::Statistics *stat) for any new drawable (or drawable derived class) that you generate (eg see Geometry.cpp). There are 20 types of drawable counted - actually only 14 cases can occur in reality. these represent sets of GL_POINTS, GL_LINES GL_LINESTRIPS, LOOPS, TRIANGLES, TRI-fans, tristrips, quads, quadstrips etc The number of triangles rendered is inferred: each triangle = 1 triangle (number of vertices/3) each quad = 2 triangles (nverts/2) each trifan or tristrip = (length-2) triangles and so on.
