The BackBlur property of the DepthOfField class determines whether the areas behind the focal point should be blurred. This property is part of the depth of field effect, which simulates the focus range of a camera lens, allowing for more realistic rendering of scenes by blurring objects that are not in focus.
To use the BackBlur property, you need to have an instance of the DepthOfField class. You can then set this property to true or false depending on whether you want to enable or disable the blurring of objects behind the focal point.
// Create an instance of DepthOfField DepthOfField depthOfField = new DepthOfField(); // Enable back blur depthOfField.BackBlur = true; // Disable back blur // depthOfField.BackBlur = false;
