Lab 5: Creating an Animation Loop with Music
IDS252: 3D Animation, Spring 2013

Goals

• Continue practice using keyframes, path animation, etc.
• Learn how to import and respond to sound.
• Learn a little about skeletons, forward kinematics, inverse kinematics.
• Deliverables: A 10 second animation loop that responds to a 10 second sound loop. Place in the designated folder on cs-render. See Evaluation Sheet (pdf).

Files and Folders

• When you create a new project for the animation, place it on the cs-drive drive in the folder: \IDS252Sp13\Lab5\MayaProjects\your_name.
• When you have completed the lab, please move your final animation over to the folder: \IDS252Sp13\Lab5\FinalAnimations\
• Make sure that the name of your final animation is named in a similar manner as in previous labs.

Maya Tutorials

• The supplementary file (IK_MechArm.mb) that you will need for the IK tutorial listed below can be found in the same folder (called Anim) of tutorial files which you downloaded in the previous lab.

• In Maya, go to Help -> Tutorials. Click on the link Getting Started with Maya 2012. In the contents, click on Getting Started with Maya, and then Animation. Do the following lessons:
  

  • Lesson 5: Inverse Kinematics.
  • Lesson 3: Path animation. Do this, if you didn't do it for the last lab

  The above tutorials will not be collected.

10 Second Animation Loop

• Project Setup: Create your new project, following these directions for folders and other settings.

• Music Assignments: Hopefully, by the lab time, you will find 10 second music loops in the folder \IDS252Sp13\Lab5\MusicLoops. Below are the assignments:

  Forrest	Bounce 7.aif	James	FYS ASSIGN 7 FUNKY LOOP.aif
  Mara	sea song.aif	Jack	KGA assign 7.aif
  Juliana	loop a.aif	Emma	KGA assign 7.aif
  Katie D.	MSW 10 sec loop.aif	Darrin	New Sound.aif
  Trevor	creepy space fixed.aif	Austin	Oh_10 sec trial 2.aif
  Kelci	Samurai Squad .wav	Jessica	sea song.aif
  Yang	TCR 10 Second Audio.aif	Vinny	The Rise of Golgometh MCN.aif
  George	Samurai Squad .wav	Harry	Oh_10 sec trial 1.aif
  Collin S.	JLL 10 Second Audio.aif	Ian	Bounced up redo.aif
  Xavier	10 Second Loop CDS Fix.aif	Colin Y.	loop b.aif
  Kate Z.	FYS ASSIGN 7 FUNKY LOOP.aif

  Note, there are several longer sounds in the "optional" folder. If you want to swap the sound file you have with one of these, let Prof Orr know in class on Friday. If your original assignment is not shared with anyone else, then we may want to find someone else to do it.

• Loading Music into Maya:

  • Copy your sound file into your project and place it into the "sound" folder.
  • Below are the key things that you need to do to work with sound:
    • If you haven't done so already, remember to set the frames-per-second (fps) to 30 and the "Playback Speed", select "Real-time (30fps)". Note, if you don't do this, you won't be able to hear the sound.
    • To load in a sound file, go to File;Import... from Maya's main menu. Select the sound file you copied into your project folder (if your project is not set, Maya will place you in the wrong folder. You should always set the project).
    • To see the sound wave in the timeline at bottom of Maya window, right click on the timeline, choose Sound, and select the name of your sound file.
    • You need to expand the time range slider so you can see the entire sound wave. To do this, right click on the time slider and choose "Set Range to -> Sound Length". The length should be very close to 300 frames if the sound is 10 seconds long. If it isn't exactly 10 seconds long, use whatever length the sound is.
    • More detailed directions for importing sound files can be found in the Maya Help (do a search on "Add audio to your animation").

• Creating Your 10 Second Animation Loop: Listen to the sound multiple times to develop a sense of the movement and feeling of the music. Based on this, create an animation that is your response to the music (remember, there is no right or wrong). As in the last lab, your animation should be a loop, i.e. it's end should transition seamlessly back into the beginning. Be prepared to discuss how you applied at least several of the animation principles listed below. Refer to UW Principles for detailed explanations.

  Squash & stretch Anticipation Staging Follow-through Overlapping action Slow-in, slow-out Arc vs linear motion

  Secondary action Timing Exaggeration Knowledge of technique Observation and translation Appeal Imagination

• Using a Rigged Character: If you wish, you may use the rigged character bloke (bloke_v2.8.ma), whose maya file may be found in the folder on cs-render in \IDS252Resources\RiggedCharacters. You need to copy the file over to your project.

• Combining Sound and Animation: When you render the frames in Maya, the sound is not attached. You must combine the frames and the sound separately. To add sound to the final quicktime animation, you will need to load the sound file into Adobe Premiere elements along with the image frames. The frames are dragged down to the video track and the audio needs to be dragged down to the audio track. Make sure the video and audio are properly aligned. Generate the quicktime as you did in the last lab. (See directions)

Evaluation

Before class on Wed, Feb 20, place your final animation on cs-render in the folder \IDS252Sp13\Lab5\FinalAnimations. Animations will be graded based on these questions, which will be discussed during the critique.
