<description>This example has three double-parabolic CRLs. To visualize them nicely and to see that they do focus x-rays, start Glow, and:
- In Navigation select all 6 lens surfaces in the column "Surface" (if hidden, enlarge the window) and center the view at one of them.
- In Transformation set all 3 Log scales equal to 4.
- In Color / Color Axis select xzprime -- the axial divergence, :math:`(xz)'=\sqrt{x'^2+ z'^2}`.
- Rotate and zoom the view as convenient.
- Observe with a close zoom that the footprint points deviate from the surface because the surfaces are too simplified by OpenGL. To make the surfaces more precise, put two equal larger numbers as tessellation parameters in Scene. This will result in better surfaces but also slower 3D manipulation of the scene.
