Technical Support - Glossary |
| target frame | The
currently hilighted thumbnail view in the frame cylinder or view area of the “acquire” panel. |
| temporal compression | Image compression that is performed between frames in a sequence. This compression technique takes advantage of redundancy between adjacent frames in a sequence, to reduce the amount of data that is required to accurately represent each frame in the sequence. Sequences that have been temporally compressed, typically contain key frames at regular intervals. |
| thumbnail view | A miniature representation of a graphic image. |
| tile array | The
order and quantity of segments into which a flat panoramic image is divided when compression occurs. |
| tilt | To move a camera or point of view vertically. |
| tilt angle | The
angle of tilt. Tilt angles are measured in radians or degrees, where positive values tilt up. |
| tilt constraint atom | An atom in a QuickTime VR file that contains information about the initial tilt angle constraints for a panorama. Compare field-of-view constraint atom, pan constraint atom. |
| tilting speed | The
relative speed of panning and tilting. This speed should be from 1 (the slowest speed) through 10 (the fastest speed); the default panning and tilting speed is 5. |
| timeout | See mouse-click timeout. |
| transition | The
movement between two items in a movie, such as from one view in a node to another view in the same node, or from one node to another. |
| transition effect | Any special visual effect associated with a transition. |
| transition property | A
property of a VR movie whose value determines a specific kind of transition
effect. translate To reposition an object by changing the current view center. |
| translate | To
reposition an object, by changing the current view center. translate mode button - A button in the controller bar that allows the user to enable or disable translate mode. |
| translate mode | An interaction property for objects whose value determines whether dragging the mouse causes an object to be translated ( true ) or to be panned or tilted ( false ). |
| translate mode button | A button in the controller bar that allows the user to enable or disable translate mode. |
| translation key | The key on a keyboard that the user can hold down to enable translate mode. |
| Uniform Resource Locator (URL) | An address of a page on the World Wide Web. URL See Universal Resource Locator. |
| URL hot spot - | A hot spot that is associated with a URL. |
| user data | Auxiliary data that your application can store in a QuickTime movie, track, or media structure. The user data is stored in a user data list; items in the list are referred to as user data items . Examples of user data include a copyright, date of creation, name of a movie's director, and special hardware and software requirements. |
| user data item | A single element in a user data list. |
| user data list | The collection of user data for a QuickTime movie, track, or media structure. |
