Coincidence of a Point and Other Object

If two geometric objects have the same type, then coincidence constraint presumes equality of two geometric objects. However, in the current version of C3D Solver this constraint is valid only if one of the arguments is a point.

If one of the coincidence arguments is a point, and the other one is a curve, then the constraint would define the point lying on the curve.

The coincidence constraint is defined by the following method:

constraint_item GCE_AddCoincidence(GCE_system gSys, geom_item g[2])  

The function would add to gSys system the coincidence constraint for two geometric objects (g[0] and g[1]) and would return the constraint descriptor.
