    SoInertiaMomentProcessing2d measures the resistance of an object to changes in its motion around a given axis of rotation. This class computes a measure of an object's resistance to changes in its rotational motion. The moment of inertia of an object on a given axis describes how difficult it is to change its angular motion around that axis.

    For a point mass m the moment of inertia I is simply m times the square perpendicular distance r from the axis of rotation:

    On a digital image a pixel intensity can be considered as a mass. Then for an object of a binary image, m is a constant equal to 1. Thus, the moment of inertia is the sum of the square perpendicular distances from the axis: Where:

    • x is an object pixel
    • p(x) is the orthogonal projection of x onto the axis of rotation.

    The rotation axis is defined by a point (rotationCenterX and rotationCenterY) and an orientation (rotationAngle).

      • inBinaryImage

        public final SoSFImageDataAdapter inBinaryImage
        Deprecated.
        The input binary image. Default value is NULL. Supported types include: binary color image.

      • rotationCenterX

        public final SoSFInt32 rotationCenterX
        Deprecated.
        The X coordinate of the rotation axis. Default value is 1024.

      • rotationCenterY

        public final SoSFInt32 rotationCenterY
        Deprecated.
        The Y coordinate of the rotation axis. Default value is 1024.

      • rotationAngle

        public final SoSFFloat rotationAngle
        Deprecated.
        The orientation of the rotation axis in degrees (not radians). A positive value means that the angle is taken from the positive X axis to the postive Y axis. Default value is 10.0f.
