| action filter function
|
An
application-defined function that is called by a movie controller component
each time the component receives a movie controller action. Your filter
function can handle the action itself or refer it back to the movie controller
component for processing |
| angular unit | A
unit for measuring angles. For the QuickTime VR Manager, the default
angular unit is degrees. Compare degree, radian. |
| animation setting | A value that specifies characteristics of an object node, while it is playing an animation. For example, one animation setting determines whether an object node animation is looped. |
| antialiasing | The smoothing of jagged edges on a displayed shaped by modifying the transparencies of individual pixels along the shape's edge. |
| application programming interface (API) | The total set of constants, data structures, routines, and other programming elements that allow developers to use some part of the system software. |
| area of interest structure | A data structure that delineates a rectangular area in the back buffer. Defined by the AreaOfInterest data type. |
| atom | The
basic unit of data in a movie resource. Defined by the QTAtom data type.
There are a number of different atom types, including movie atoms, track
atoms, and media atoms. There are two varieties of atoms: container atoms,
which contain other atoms, and leaf atoms, which do not contain any other
atoms. |
| atom container | An
opaque object that contains one or more atoms. Defined by the QTAtomContainer
data type. |

| autoscrolling | The

| back
buffer |
An
image buffer maintained by QuickTime VR for panoramic nodes that
contains an image that has not yet been corrected. Compare prescreen
buffer. |
| back buffer imaging procedure | An
application-defined procedure that is executed at established times; you
use this procedure to access the back buffer. Compare prescreen buffer
imaging completion procedure. |
| base resolution | The
highest resolution image present in a node. |
