public class SoRadialGradientContourProcessing3d
extends SoImageVizEngine

SoRadialGradientContourProcessing3d engine The SoRadialGradientContourProcessing3d engine performs a projected gradient computing the directional vector

For an introduction, see:

• section Edge Detection
• section Images Filters
• Introduction to Gradient

In the continuous 3-D case, for a given pixel and knowing the gradient , and , the projected gradient of an image is defined along the unitary vector , as:

The SoRadialGradientContourProcessing3d performs a projected gradient computing the directional vector from the contour of objects. For a pixel in the image, the center taken into account is the closest pixel contour of the closest object.
