5. Create a Sphere geometry from the 3D/Geometry toolbox and attach its input to
SphericalTransform1's output.
6. View Sphere1, making sure you're viewing the 3D Viewer.
You're probably not seeing much. This is because spheres are, by default, created
with a size of1.The buildings, onthe other hand, are very big. Because yourper-
spective camera (the one you're viewing the 3D scene through) is probably set
to view the buildings, the sphere is too small to be seen. You'll have to scale the
sphere up. It's supposed to be as big as the sky, after all.
7. Change the Uniform Scale property of Sphere1 to 500,000. If you still can't see
the sky, move back by using the - key or the scroll wheel until you do.
You should now see the sky dome ( FIGURE 11.24 ).
