  1. Facial Animation with OpenGL By Nick Patti

  2. Project Synopsis • Model a 3D human head • Have it recite a line from a film • Manipulate “muscles” in way to make the model emote

  3. Research and Helpful Texts • Various animating techniques • http://www.dipaola.org/stanford/facial/class8notes.html • Computer Facial Animation by Parke and Waters • Geometry-based Muscle Modulation for Facial Animation • http://www.mpi-inf.mpg.de/resources/FAM/publ/gi2001.pdf

  4. To-do List • Find a face model, integrate with Prog 0, find a good line for model to recite • Finish updating Prog 0 code to operate within desired specs • Find out how to play sound using C++, implement cueing sound when button is pressed • Project update and sanity check, experiment with animating with current working version of project • Begin animating the face to the appropriate specifications. Clean up project and submit!

  5. Progress: Reading Files • .coor .poly file format is not feasible • Not a conventional file format that can easily be found • Requires that I make my own model, too much time • Experimented with other file formats • Most spat out really weird junk… • A reliable file format, .obj • Easy to interpret data, including vertices, normals, and even textures

  6. Progress: UI • Revamp previous system from Prog0 • Mouse controls rather than keyboard controls to rotate and zoom camera • Press ‘p’ to play the animation and audio • Found BASS Library to be quite useful • Possible spring/keyframe animation algorithm to animate

  7. Progress: Animation • Facial animation not really new, many ways to go about it • Parke and Waters’s book contains various techniques using OpenGL • Cannot access examples, however… • Expressions Toolkit may also serve as a useful starting point • Still happy to take suggestions, though • A means to animate faces without an underlying substructure, perhaps?
