Q3BackfacingStyle_New

You can use the Q3BackfacingStyle_New function to create a new backfacing style object.

TQ3StyleObject Q3BackfacingStyle_New (
TQ3BackfacingStyle backfacingStyle);

backfacingStyle

A backfacing style value.

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.
