SoRadialGradientContourProcessing2d engine. The SoRadialGradientContourProcessing2d 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 2-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 SoRadialGradientContourProcessing2d engine 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.
It is a common way to get the recursive gradient in X and Y directions for input image Gx and Gy, using a spread of 60.
The projected resulting gradient image is the Normal Gradient. Simultaneously, the tangential gradient could be computed with the option GRADIENT_NORMAL_TANGENTIAL of ProjectionMode
