Notes
=====

Callbacks are HOOPS-specific functions to intercept parts of the drawing/selection process. It is in the form of one or more comma separated *action = function* pairs, where the *actions* are specific options defined by HOOPS, and *functions* are names registered with HOOPS along with the address of the appropriate executable subroutine. For further information on callbacks please refer to the HOOPS I.M. section of the 3dGS Reference Manual.
