T

take

A snapshot in time of an animation instance.

Note: Time can be measured in hours, minutes, seconds, and frames, or in frames per second.
tangent handle

The visual representation of the tangent of a keyframe on a function curve. Tangent handles let you change the slope of the curve on either side of the keyframe.

TCB

Tension, Continuity, Bias.

tesselation

A step in the rendering process in which the shapes of an object’s surface mesh are rearranged into triangles.

texture

Various texture assets let you apply image or video files to materials, layered textures, and models. Textures are most commonly used to add detail to a model’s surface without adding to the model’s geometry. Use textures with materials and shaders.

timecode

The value that indicates the current position in time of the current take.

Timewarp

A curve that alters the shape of a function curve and changes the timing of an animation.

See also function curve .

track

A course along which something moves, or a sequence of events through time.

In MotionBuilder, there are two types of tracks. In the Motion Blend window, tracks can contain motion data and let you blend takes into a single result track. In the Story window, tracks can contain motion data, keyframe animation, audio and video, and let you blend specific types of clips along the timeline.

Track Row Column (TRC)

A file format created by Motion Analysis Corporation to specify the positions of markers placed on a subject at different times during a motion capture trial.

transformation

The process of changing the points on an object by translation, rotation, and scaling.

translation

The process of moving an object on one or all axes. Translation moves an object without changing its orientation.

transparency

A material property setting that defines the level of opacity for a material.

The level of visibility of an object determined by the opacity setting. When the opacity is set to 0%, the object is transparent.

The ratio of the amount of light passing through a material to the amount of light incident on the material.

TRC

See Track Row Column (TRC).

trigger

In the Animation Trigger window, a device, such as a joystick or keyboard, that allows you to execute motion clips to test the transitions you created between them.

triggering group

A collection of motion clips and the triggers that initiate their execution.

T-stance

The neutral pose of a biped character similar to a “T” pose in which the arms are at a 90-degree angle from the body, the legs are fully extended, the feet are flat on the floor, and the spine is straight.
