Custom Cursor Atoms
The hot spot information atom, discussed in “Hot Spot Information Atom,” allows you to indicate custom cursor IDs for particular hot spots that replace the default cursors used by QuickTime VR. QuickTime VR allows you to store your custom cursors in the VR world of the movie file.
Note: If you’re using the Mac OS, you could store your custom cursors in the resource fork of the movie file. However, this would not work on any other platform (such as Windows), so storing cursors in the resource fork of the movie file is not recommended.
The cursor parent atom is the parent of all of the custom
cursor atoms stored in the VR world. Its atom
type is kQTVRCursorParentAtomType ('vrcp').
The child atoms of the cursor parent are either cursor atoms or
color cursor atoms. Their atom types are kQTVRCursorAtomType ('CURS')
and kQTVRColorCursorAtomType ('crsr').
These atoms are stored exactly as cursors or color cursors would
be stored as a resource.
