Managing Backfacing Styles
QuickDraw 3D provides routines that you can use to manage backfacing styles.
Q3BackfacingStyle_New
You can use the Q3BackfacingStyle_New function to create a new backfacing style object.
TQ3StyleObject Q3BackfacingStyle_New (
TQ3BackfacingStyle backfacingStyle);
DESCRIPTION
The Q3BackfacingStyle_New function returns, as its function result, a new style object having the backfacing style specified by the backfacingStyle parameter. The backfacingStyle parameter should be one of these values:
kQ3BackfacingStyleBoth
kQ3BackfacingStyleRemove
kQ3BackfacingStyleFlip
If a new style object could not be created, Q3BackfacingStyle_New returns the value NULL .
To change the current backfacing style, you must actually draw the style object. You can call Q3Style_Submit to draw the style in retained mode or Q3BackfacingStyle_Submit (described next) to draw the style in immediate mode.
SEE ALSO
See "Backfacing Styles" for a description of the available backfacing styles.
Q3BackfacingStyle_Submit
You can use the Q3BackfacingStyle_Submit function to submit a backfacing style for drawing in immediate mode.
TQ3Status Q3BackfacingStyle_Submit (
TQ3BackfacingStyle backfacingStyle,
TQ3ViewObject view);
Q3BackfacingStyle_Get
You can use the Q3BackfacingStyle_Get function to get the backfacing style value of a backfacing style.
TQ3Status Q3BackfacingStyle_Get (
TQ3StyleObject backfacingObject,
TQ3BackfacingStyle *backfacingStyle);
Q3BackfacingStyle_Set
You can use the Q3BackfacingStyle_Set function to set the backfacing style value of a backfacing style.
TQ3Status Q3BackfacingStyle_Set (
TQ3StyleObject backfacingObject,
TQ3BackfacingStyle backfacingStyle);
