void OEGetCenterAndExtents(const OEMolBase &mol, float *ctr, float *ext) Determines the bounding box that can encompass the molecule. The length of each side of the box is output in the 3-element array extents. The geometric center of the box is output to the center parameter. *mol* The molecule to calculate center and extents. *ctr* The output box center vector. The vector must have a defined size of at least three. *ext* The output box lengths vector. The vector must have a defined size of at least three. .. note:: The center of the box is different from the center-of-mass of the molecule.
