How to: Hit Test in a Viewport3D
This example shows how to hit test for 3D Visuals in a xref:System.Windows.Controls.Viewport3D.
Because xref:System.Windows.Media.VisualTreeHelper.HitTest%2A returns 2D and 3D information, it is possible to iterate through the test results to read only 3D results.

The xref:System.Windows.Media.HitTestResultBehavior in the following code determines how the hit test results are processed. UpdateResultInfo and UpdateMaterial are locally defined methods.
