PURPOSE
Aborts traversal in progress.
CALLING SEQUENCE
HIC_Abort_Update (nr)
HIC_Abort_Selection (nr)
----------------------------------------------------- nr HT_Rendition Net rendition. Passed by reference. -----------------------------------------------------
DETAILS
These functions set flags to signal the system that you wish to abort the traversal in progress. The first is for use in the "draw ..." callbacks and the second for the "select ..." callbacks.
The system can abort the traversal at an appropriate time after this function is called. On abortion the database is returned to its pretraversal state. In the case of abortion of a display update, the display is left in its partially drawn condition.
NOTES
HIC_Abort_Selection has no effect if you call it from other than a "select ..." callback function.
PURPOSE
Adds a cutting plane to affect subsequent geometry.
