I don't think you can hitest primitives in the visual brush. What you can do
thought is to put the buttons on two separate meshes or 3d visual models and
hittest against them.
Hittesting in 3D is done using the VisualTreeHelper.HitTest method. Using
this method is straightforward. I believe there is samples in the SDK about
this. One place that I'm sure you can find implementation of 3D hittesting
is in the sample code from the north face demo http://msdn.microsoft.com/windowsvis...html/fluid.asp
Download the code and look at the Video Carousel code.
