public class SoCentroidProcessing2d extends SoImageVizEngine
SoCentroidProcessing2d
engine. TheSoCentroidProcessing2d
engines computes the centroid of object.For an object without holes, the centroid is a unique point. For an object with holes, the centroid is made of rings surrounding each hole, as in Figure 1. The
SoCentroidProcessing2d
engine performs successive thinnings with rotations and until convergence, using the D configuration: where means "don't care".Do not confuse the centroid with a classical center of gravity, which may be outside the object as in the case of a boomerang-shaped particle. However, for quasi-convex objects the centroid is very close to the centre of gravity.
