[HelloSupport]

Thank you for your prompt reply.  Actually, I don't need rectangles with borders, just rectangles.  I have shown this in the new MainWindow.xaml.cs.   The program starts up as shown in the attached Screenshot3.  I then can move the mouse around so that it looks like screenshot4.  This is how i would like my rectangles arranged,with the orange rectangle on the bottom and the yellow on the top.

I have the following questions:

(1) When I move the mouse around, how do I get the most recent camera parameters that the mouse movement has created?

(2) Why does the color of the rectangles change in intensity as I move the mouse around?

(3) The layout of the rectangles that I really want is shown in screenshot2, which is similar to screenshot4.  Notice that the sides of the rectangles are not slanted.  Is it possible to achieve this by changing either the camera parameters or by using a different camera type?

(4) In screenshot5 I show two groups of rectangles.  Notice that both are displayed identically.  Is it possible to show multiple groups of rectangles with the identical perspective?  Or is this impossible due to the fact that a camera is a single point and different objects will have different perspective from that point?

Thanks again for your help.
