Program Listing

class Vector

Vector class

Vector center() const

The center of the InteractionBox in device coordinates (millimeters). This point is equidistant from all sides of the box.

Vector boxCenter = interactionBox.center();
Vector max = interactionBox.max();
Vector diff = max - boxCenter;

Since

1.0

Returns

The InteractionBox center in device coordinates.
