At the home of motion capture it's no secret that we're a bunch of nerds. Our native language comprises of abbreviations, acronyms, portmanteaus and general jargon. In case you're wondering, here is what some of means...
We thought we'd start with an easy one. Now you've got MOCAP, how about these:
OPTICAL MOCAP Using outside-in optical camera arrays for tracking markers INERTIAL MOCAP Using IMU sensors (think gyro, accelerometer and magnetometers like your phone uses to rotate the screen) to track local rotation and use walking or lowest point algorithms for determining global position
MAGNETIC MOCAP Tracking using probes that intersect with a generated magnetic field MARKERLESS MOCAP A computer vision or AI system for tracking without any markers or sensors in use
ACTIVE TRACKING Motion Capture tracking using LED lights
PASSIVE TRACKING Motion Capture tracking using retro reflective markers
So, where does it take place?
THE VOLUME The space in which the mocap system lives THE STAGE The the space in which the mocap volume lives
What about those things you shout during capture..?
HERO
The best recorded take both technically and physically SAFETY The 2nd best take
MOCAP ROLLING
The queue a mocap engineer receives to record the mocap system
LINE OF SIGHT
Markers can be seen by the optical cameras
FIRST POSITION
The performers first position before action is called
QUEUE MUSIC
The queue for playing the music FACE THE GREEN PLEASE
Positive direction of our origin point in our Hoxton studio
MOCAPPUCINO PLEASE
Our technicians are flagging. They need coffee!
How should I stand?
T POSE
The start and end pose which the mocap system uses to calibrate a performer's skeletal proportions. Always used at the start and end of each recorded take.
IDLE POSE
A loop or return pose that is often used in motion blending
INTERPOLATED FINGERS
Tracking the tips of each finger and interpolating the 2nd and 3rd segments
DOLPHIN DANCE
The dance we do to calibrate the mocap system
FIGURE OF 8 DANCE
The dance we do when calibrating the mocap system. Sometimes used in combination with the Dolphin Dance for maximum accuracy.
WALKING THE GRID
Walking the volume in a grid pattern. Mostly used when calibrating the mocap system.
I've heard there are a lot of processes?
You bet...
WANDING The process of calibrating the mocap system. AKA the Dolphin Dance or Figure of 8 Dance
SETTING THE GROUND PLANE Defining the center point of the mocap system
ORIGIN POINT The centre of the world or worlds
ROM A cheeky acronym of Range of Motion. Typically run the start of each shoot for performers to test the mocap system. Also used for the initial post character editing
HERO SELECTS A process of going through each take to mark the best, both performance wise & technically
DEMARKER Getting rid of the lovely balls on the performers. By balls we of course mean markers
QUICK REFINE
A short calibration process to fix a knocked or bumped camera
MAG MAPPING
Drawing out and analysing the magnetic fields in a space prior to an inertial mocap shoot
RETARGETING
The process of applying data to a model to fix scaling, foot plants and limb to body relationships.
CLEANING
The process of removing any erroneous data from the shoot
LOOPING
Creating walk or animation cycles that perfectly blend together
This sounds...violent?
Not at all. Although we have combat fighters on our books, all the props are plastic!
SOW Our statement of works, defining the responsibilities of each company or person
RELEASE FORM The contract to allow for publication of captured images, video and data
CALL SHEET The form containing the contact detail and specifications for the shoot
SHOT LIST A document outlining the sequences and movements the require capturing in a shoot
Still don't know your inertial mocap from your idle pose? That's what we're here for. Target3D guide you in choosing the most suitable mocap products for your project. Mocap service work is also our speciality - either in our large volume studio, or on location to suit you. Get in touch with Target3D, the home of motion capture.
