cinepak	A method of image data compression.
codec	An acronym that stands for compressor/decompressor, an algorithm or specialized computer program that reduces the number of bytes consumed by large files and programs. Compression works by eliminating redundancies in data.
color depth	Indicates the number of bits per pixel used to store color information.
compression quality	Refers to the perceptive quality of an image, after it has been compressed. Lower quality usually results in smaller files.
cache buffer	See back buffer.
constraint	See viewing constraint.
container atom	A QuickTime atom that contains other atoms, possibly including other container atoms. Examples of container atoms are track atoms and edit atoms. Compare leaf atom.
controller	See movie controller component, QuickTime VR movie controller.
controller bar	A rectangular region associated with a QuickTime VR movie that displays the movie’s controls.
controller bar key	A key that, when pressed, activates a control in the controller bar. For example, the translation key is a controller bar key.
control setting	A value that specifies whether an object can wrap during panning and tilting, as well as other features of the node. Compare animation setting.
correct	To undo the cylindrical (or other) projection of a panoramic image, so that it appears as it was originally captured or rendered. Also called warp.
correction mode	The type of warping correction to be applied, when imaging a panoramic view.
current node	The node in a scene that is currently being viewed on the screen.
cursor record	A data structure that indicates which cursor to replace and its replacement cursor. Defined by the CursorRecord data type.
custom hot spot	A hot spot of a type defined by a third-party developer.
custom hot spot cursor	A custom cursor that is displayed during interaction with a hot spot.
cylindrical projection	A method of projecting a panorama onto the surface of a cylinder.
default node	The node in a scene that is displayed, when the scene is first opened.
degree	An angular unit equal to 1/360 of a complete circle. Indicated by the sign °.
destination node	The node to which a link hot spot is linked.
detent stops	Positions within a panoramic pan-head where rotation clicks to a stop.
dicing	The process of transforming a panoramic image into individual frames in a panorama image track.
