true.

Method 1 is as above. 6 actors, each a different texture.

Method 2 is to make a big texture containing all 6 images in one larger
image.(as above)

Then generate texture coordinates which are like
0-1/6, 1/6-2/6, 2/6-3/6 etc etc. But vtkTextureMapToCube won't generate the
texture coords for you. You'll have to create your own
vtkCubeFacesTextureMapper or similar. Probably easier to just stuff the
coords into a TextureCoords Dataarray. (Unless you're going to need lots of
them).
