Properties HeightDirection and Normal in the PlaneVisual3D object
#1
Given the app shown the code as the end of this post, when I first execute I get shown in image1.png.  Then when I move the mouse around I get image2.png (see attachment).

What I need to know is how the PlaneVisual3D object is drawn.  For example, suppose in image1.png I wish to see the full rectangles, i.e. have the rectangle drawn along the x-y axis instead of the x-z axis.  How would I do that?  I assume that this has something to do with HeightDirection and Normal but I don't understand how these properties work.  Thanks for any help you can give.
