returns three points of left face of e: v[0] = orgPnt( e ), v[1] = destPnt( e ) This one is not in the bindings because of the reference-to-array para

Returns the UI color for the measurement `object`.

considering all planes with given normal and arbitrary shift: dot(n,x) = d finds the box's corner for which d is minimal

find incident unvisited vertex, in case of several option prefer finding the vertex not equal to preVertex

return the plane containing points p0 and p1 and parallel to dir, with positive half-space to the left from the line p0-p1 if look from dir

should return current radius of the widget

computes the perimeter of the hole specified by one of its edges with no valid left face (left is hole)

decreases min and increases max to their closest representable value

check that we see point (projected mouse position) on edge

computes whether a point (pt) is located outside the object surrounded by this mesh using generalized winding number \param beta determines the precis

scales this quaternion to make its norm unit

returns whether the object has selectable children \param recurse - if true, look up for selectable children at any depth
