                    Projector Light Maps
                    --------- ----- ----

This subdirectory contains several maps that have been
designed for use with the spotlight "projector" feature in 
3D Studio Release 3. This new feature helps you produce 
special lighting effects which were previously impractical 
or impossible:

- artificial (user-defined) shadow maps
- "cookie"/theatrical lighting masks
- gels
- slide/movie/video projector effects
- simulated refraction/reflection effects

To illustrate some uses for projector lights we've included
some useful maps in the LIGHTS directory.

CAUSTIC.FLC    This flic is a 90-frame looping animation
               that simulates caustic light refraction or
               reflection resulting from the play of
               light on rippling water. This flic works well
               with any number of projector lights; you can
               roll and scale the lights to vary the effect.
               Furthermore, the flic is grayscale and easily 
               tints with the light color. For underwater 
               effects, bathe the environment with as many 
               lights as necessary for the proper sense of 
               scale. For reflection effects, such as sunlight
               reflected off water onto the side of a boat,
               point the lights up at the subject from the
               water's surface.

FLASHLIT.TGA   This image simulates the uneven light pattern
               created by reflecting lamps, such as  
               flashlights and headlights.

GATE.TGA       This map is a good example of an "artificial"
               shadow map--a shadow element for which no
               geometry actually exists. By using maps such
               as this one, the user can efficiently add
               detail to a scene without having to rely on
               modeling.

TREES.TGA      Another "artificial" shadow map simulating
               light shining through trees. Try projecting
               this map through an open window into a room.

WINDOW.TGA     This map is a photo of a rose window from a
               gothic cathedral; unlike the other maps here,
               it contains color. Its use goes beyond
               the shadow cast by the window's shape and
               includes the color the glass filters from the
               light. When creating stained glass "projection" 
               effects, you should first blur the bitmap 
               heavily in a paint program.
