VR World Atom Types
QuickTime VR defines a number of types of atoms that can be contained in a VR world. You can use these constants to specify a VR world atom type:
enum {
kQTVRWorldHeaderAtomType = FOUR_CHAR_CODE('vrsc').
kQTVRImagingParentAtomType = FOUR_CHAR_CODE('imgp').
kQTVRPanoImagingAtomType = FOUR_CHAR_CODE('impn').
kQTVRNodeParentAtomType = FOUR_CHAR_CODE('vrnp').
kQTVRNodeIDAtomType = FOUR_CHAR_CODE('vrni').
kQTVRNodeLocationAtomType = FOUR_CHAR_CODE('nloc'
};
Constant descriptions
-
kQTVRWorldHeaderAtomType
-
The atom is a VR world header atom. See
"VR World Header Atom Structure"
for the structure of this type of atom.
-
kQTVRImagingParentAtomType
-
The atom is an imaging parent atom, which contains one or more imaging atoms. An imaging atom describes the default imaging characteristics for one type of node in the scene. Currently, QuickTime VR supports two types of imaging atoms: object-imaging atoms and panorama-imaging atoms.
-
kQTVRPanoImagingAtomType
-
The atom is a panorama-imaging atom. See
"Panorama-Imaging Atom Structure,"
, for the structure of this type of atom.
-
kQTVRNodeParentAtomType
-
The atom is a node parent atom, which contains one or more node ID atoms that specify the IDs of all the nodes in the scene.
-
kQTVRNodeIDAtomType
-
The atom is a node ID atom, which specifies the node ID of a single node in the scene. Each node ID atom has a single child, which is a node location atom.
-
kQTVRNodeLocationAtomType
-
The atom is a node location atom. See
"Node Location Atom Structure"
for the structure of this type of atom.
