coords.Coords.diag_size

Coords.diag_size()

Return the diagonal size of the bounding box of the Coords.

Returns

float

The length of the diagonal of the bounding box.

Notes

All the points of the Coords are inside a sphere with the center() as center and the diag_size() as length of the diameter (though it is not necessarily the smallest bouding sphere). diag_size() is in general a good estimate for the maximum size of the cross section to be expected when the object can be rotated freely around its center. It is conveniently used to zoom the camera on an object, while guaranteeing that the full object remains visible during rotations.
