fz_objt_alys_get_objt_cog

Description

Calculates the center of gravity of an object. Depending on which topology type is encountered, different algoritms are used :

POINT : The coordinate
OPEN/CLOSED WIRE : Weighted average of segment midpoints
SINGLE FACE SURFACE : Face cog
SURF SOLID AND
MESHED SURFACE : Weighted average of all face cogs
SOLID : Volumetric cog
MIXED TOPOLOGY : Average of all facetted coordinate points
