?—? Use color images for added dimension. Darker areas will hold back more light,
and lighter areas will shine more light. For example, you can create the effects of
light through a stained-glass window.
?—? Use softer, blurry images for added effects.
?—? Use animation sequences as projection images.
?—? Use imported movie files! Create real projected movies in your animation by projecting
an AVI or QuickTime movie onto a movie screen in 3D.
?—? Create windowpanes and project them onto your set to create the look of light
coming through a window.
You also can apply volumetric effects for projection images. In Chapter 15, ???Advanced
Cameras and Rendering,??? you??™ll learn about volumetric lighting and the cool things you
can create with this feature.Combine those techniques with these lighting techniques and
you??™re ready to rock!
Using Area Lights
Distant lights and point lights produce hard-edged, ray-traced shadows. Ray-traced shadows
take more time to calculate, which of course means more time to render. Spotlights
also can produce ray-traced shadows, but with spotlights you have the option to use
shadow maps, which take less time to render than ray-traced shadows.
