The scene may include heirarchically modeled objects,lights, texture-maps, bump-maps, and camera control. <b><hr>Assignment</b><p>Produce a scene which has several objects which move. There should be at leastone example of rotory or periodic motion and at least one example of linear motion. You may want to mix physically-based animation with kinematicanimation.Some of the objects should have a hierarchical structure and you shoulddemonstrate use of polyhedra and parametric surfaces.Lighting should be appropriate to your scene. Surface propertiesshould be controlled to simulate appropriate materials. CA or reaction based texture mapsmay be appropriate for some objects.<p><b> The animation must startwith a title frame which includes title, author, and copyright notice.</b>The following program is one example of a title page generator.<ul><li> <!WA1><!WA1><!WA1><!WA1><!WA1><!WA1><!WA1><!WA1><a href="http://www.tc.cornell.edu/Visualization/Education/cs418/labs/titles1995.net"> titles.net </a><li> <!WA2><!WA2><!WA2><!WA2><!WA2><!WA2><!WA2><!WA2><a href="http://www.tc.cornell.edu/Visualization/Education/cs418/labs/titles1995.cfg"> titles.cfg </a></ul>The the system-supplied DX fonts look too thin in MPEG compressed animations(or on videotape).

Did you exploit the information from the earlier exercises? <li>Clarity of the program. You should be able to explain your program. You should usetransmitters/receivers, macros, and comments in the "Notation" field of each moduleso that you and the grader can understand the program. Control panels, if any,should be well organized, labeled, and with the appropriate numeric ranges.</ol><p>Be sure to see past year's Lab 9 <!WA6><!WA6><!WA6><!WA6><!WA6><!WA6><!WA6><!WA6><a href="http://www.tc.cornell.edu/Visualization/contrib/cs418-sp94/cs418.html">animation results </a><p><!WA7><!WA7><!WA7><!WA7><!WA7><!WA7><!WA7><!WA7><img src="http://www.tc.cornell.edu/Visualization/Education/cs418/gifs/leftarrow.icon.gif">Back to <!WA8><!WA8><!WA8><!WA8><!WA8><!WA8><!WA8><!WA8><a href="http://www.tc.cornell.edu/Visualization/Education/cs418/index.html">Main Page</a> <P><hr>Last modified, 1/18/96, B.
