The position of a sensor recorded by each camera at each frame. All samples from each camera generate a three-dimensional representation of each sensor’s position in time when processed.
See also keyframe .
A representation of a three-dimensional world in which objects are placed and animated using a coordinate system.
See also 3D coordinate space .
The data captured from an optical motion capture session.
See also current segment , and motion capture .
A reflector or light source attached to a performer’s body. Sensors are tracked by optical cameras during the capture process. Captured data is combined to create segments.
See also motion capture and segment .
In 3D modeling, the term “shader” is used to describe an algorithm that specifies how a surface responds to light. In MotionBuilder, “shaders” are assets that you apply to models to create different types of effects. Various types of shaders can define how a surface responds to light, or create special effects like cartoon outlines and bump mapping. You can also use shaders to generate shadow maps and light maps for scenes with a static light source.
MotionBuilder also supports custom shaders created using the Open Reality® SDK.
In the Character Face settings, a Character Face modified to portray a particular expression, such as “angry”.

The action of fast-forwarding or rewinding through audio or animation while the audio is playing. A faster form of Jogging.
The process of calculating the position of both the forward kinematics and inverse kinematics rigs, then applying these results to the linked model while observing the settings in the Character Settings pane.
The results of calculating each rig. For example, IK solving refers to the result of calculating the IK rig.
In MotionBuilder, the result of all calculations, rigs, and settings when using the character engine.
A sensor, a node from a skeleton, or a model from a hierarchy of models that stabilizes the entire blending object and corrects problems such as foot sliding.
See also blending object .
A problem with optical motion capture wherein two markers either cross or pass close to each other, causing the capture system to misinterpret the markers and label the segments incorrectly.
