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).

- Field Detail
  - inBinaryImage
```
public final SoSFImageDataAdapter inBinaryImage
```
    The input binary image. Default value is NULL. Supported types include: binary color image.
  - rotationCenterX
```
public final SoSFInt32 rotationCenterX
```
    The X coordinate of the rotation axis. Default value is 1024.
  - rotationCenterY
```
public final SoSFInt32 rotationCenterY
