Movement Capture Laboratory School of Arts and Humanities Erik Jonsson School of Engineering and Computer Science University of Texas at Dallas

Slide 2

What is Mocap? Movement catch (mocap) is examining and recording movement of people, creatures, and soulless items as 3D information. The information can be utilized to study movement or to give a deception of life to 3D PC models.

Slide 3

Applications Entertainment Medicine Arts/Education Science/Engineering

Slide 4

Entertainment: Live Action Films Computer created characters in cutting edge movies.

Slide 5

Entertainment: 3D PC movements Characters in PC energized documents (e.g. Symbol, Polar Express, Monster House )

Slide 6

Entertainment: Video Games Video amusements by Electronic Arts, Gremlin, id, RARE, Square, Konami, Namco, and others, (e.g. Foe Territory)

Slide 7

Medicine (e.g., stride investigation, restoration) Sports medication (e.g. damage anticipation, execution examinations, execution improvement) Gait Analysis Service

Slide 8

Arts/Education Dance and showy exhibitions Archiving (e.g., Marcel Marceau) OSU/ACCAD

Slide 9

Science/Engineering Computer Science (e.g., human movement database, indexing, acknowledgments) Engineering (e.g., Biped robot advancements) Ergonomic item outline Military (e.g., field works out, virtual teachers, and pretending amusements)

Slide 10

Mocap activity Motion catch liveliness is not quite the same as keyframe activity as far as how movement is made. Same standards apply to mocap activity & keyframe liveliness! A mix of movement catch liveliness and keyframe activity is frequently utilized.

Slide 11

Keyframe movement A keyframe is a drawing of a key minute in a vivified succession, where the movement is at its great. Inbetweens fill the crevices between keyframes. Each movement is made by illustrators.

Slide 12

Advantages of mocap activity Faster to make (just if a set up generation pipeline exists.) Secondary movements and all the inconspicuous movements are caught - > more authenticity. Physical collaborations amongst entertainers and props can be caught.

Slide 13

Disadvantages of mocap activity Cost. Controlling mocap information is regularly troublesome - > Re-catching or key encircling a shot with awful information is frequently less demanding. Mapping mocap information of an entertainer to a character with an alternate extent frequently causes issues.

Slide 14

Types of mocap hardware Magnetic frameworks Mechanical frameworks Optical frameworks

Slide 15

Magnetic frameworks Utilize sensors set on the body to quantify the attractive field produced by a transmitter source.

Slide 16

Magnetic frameworks  Require no uncommon lighting condition.  Sensors are never impeded. X Require a metal-expense environment.

Slide 17

Mechanical frameworks Exoskeleton with point sensors.

Slide 18

Mechanical frameworks  Measure joint edges (no marker ID issues).  Sensors are never blocked. X Breakable! X Configuration of sensors is altered. X Constrains on joints.

Slide 19

Optical frameworks The cameras are outfitted with infrared LED\'s and channels. (Channels improve the difference of the picture.) The cameras see reflector markers.

Slide 20

Optical frameworks  Higher testing rate.  Larger catch space. X Markers are infrequently blocked - > marker ID issues. X Provide just positional information - > joint points should be registered.

Slide 21

Mocap framework at UTD Vicon optical framework - Best framework in Academia! 8 fast MX 13 (up to 1000 fps) and 8 high-determination MX 40 (4 million pixels) cameras. Catch up to 5 entertainers immediately.

Slide 22

Mocap framework at UTD Vicon optical framework - Best framework in Academia! 8 rapid MX 13 (up to 1000 fps) and 8 high-determination MX 40 (4 million pixels) cameras. Catch up to 5 entertainers immediately.

Slide 23

Production pipeline outline Calibrate the framework. Fit a bland skeleton to the subject\'s extent (subject adjustment). Catch shots & recreate 3D directions utilizing the adjusted subject. Join the subject particular skeleton to a CG character\'s skeleton and alter movement (in MotionBuilder). Add skin to the CG character, alter movement, and render (in Maya).
