I just added an example file to the top of the example:

0.0 0.0 0.0 1.0 2.0 3.0
1.0 0.0 0.0 4.0 5.0 6.1
0.0 1.0 0.0 7.2 8.3 9.4

When I run the example with this file, I see 3 red dots, and as I rotate
them, the change from red to black (because of the normal which causes VTK
to change the light reflected off of them).
