Project 3 : Lighting<br>

   Date Assigned: Tuesday, July 5th (week 4)<BR>
    Date Due:  Monday July 11th, 11:59am (1 hour before class)<BR> 
<p>
    Reading: Chapters 7 and 8 (Kerlow)<BR>
    Also Recommended:<a href="http://www.siggraph.org/education/materials/siggraph_courses/s96_course30.pdf"> Pixel Cinematography: A Lighting Approach for Computer Graphics</a>
<P>
    In this assignment you will experiment with character and mood
    lighting. <!--This assignment is designed to be done in Maya.-->
<P>
  You can either choose to work on your own, or work with a group of your choosing.
 Each member brings along all the models used by his/her groups in the previous
    two assignments. Choose from these at least two shaded models that
    fit together well. Compose these models into a scene and light the
    scene in the ways described below.
<P>
   <H3> Getting started</h3>

    To get used to creating and manipulating lights in Maya Tutorials:Rendering:Lesson 3.

<h3>    What to do</h3>
<OL>
<li> Create a simple setting that makes sense for the objects
       your groups has chosen -- a room, or a backdrop and a
       surface. Choose one object to be the main character and place
       the models in the scene. The main character does not have to be
       in the foreground; lighting can be used to direct attention to
       the main character wherever it is.
<UL>
You can use models from:
<li>  the class (feel free to ask class members for maya binary files from the last project)
  <LI>  the web (warning.. web ones may be hard to import and have bad/missing textures...)
  <li>  make new ones....

</UL>

    <li> Light the scene so that the main character stands out. Keep
       the background lighting as simple as possible. Think of this as
       "hero lighting." Some standard lights that you might want to
       use include:
<UL>
    <LI>      Key light.
<br>
              The brightest light, the main source of illumination for
              the character. Chosen to make the character look
              good. Usually comes from the side and above.

    <LI>      Fill light.
        <BR>      Fills in the dark areas, softens shadows. Usually a non-specular light. 
          
	  <LI>Rim light (a.k.a. kicker light).
              <br>Illuminates character from the non-key side. Helps to define shape and contour. 
          
	  <LI>Bounce light
          <BR>
	      Light "reflecting" up from the floor or tabletop. Fills
    in dark areas on the undersides of the character.
</UL>
       <li>Using the same objects, same composition, and same camera
       angle, light the scene again. This time, choose a different
       object to emphasize and choose a specific mood to convey. It is
       critical that as a team you come up with a definite mood or
       atmosphere that you are trying for. As in the shading
       assignment, the mashed potatoes defense will not stand.

       <LI>(Optional) Light the scene in some other interesting
       way. Some suggestions: as a fine arts painting, as an
       advertisement, as a night scene.
</OL>
<H3>    What we're looking for</h3>

    We have different expectations for the results of each part of the assignment.
<OL>

    <li> The first part is just to give you something to light. Focus
    on achieving an interesting composition and a sense of
    relationship between and among the objects. Remember to model for
    your scene; clever use of camera angles and/or background
    paintings can minimize the need to actually build things like
    walls and floors.

     <li> The second part is an exercise in character lighting. Play
     with the color and placement of the lights in your scene to get a
     feel for the kind of effects that they can have.

<UL> 
        
    <LI> Make sure the main character looks good: not too flat, not
        overworked; not too shiny, not too dull; not too ruddy, not
        too sickly. 

    <li> Make sure the main character does not fade into the
        background. You might do this with a kicker light, or by
        making the character lighter or darker than the area
        immediately behind it.  

    <LI> Make sure that the main character
        looks like it belongs in the scene, as opposed to something
        that has been rendered separately and pasted in. The light
        colors and directions used for the character should match the
        background. Shadows help here. 
 </UL> 

<LI> The third part is an exercise in the power of lighting as a
        cinematographic and artistic tool. Think about the interplay
        of light and shadow, the use of color, the variation of
        lighting within a scene. Tell a story with a single image.
    <br> You can change scene elements for this image.
<LI> You have free rein here.
</OL>
