Triangle Flags Masks
The flags parameter for the QADrawTriGouraud and QADrawTriTexture functions specifies a triangle mode, which determines how the drawing engine draws a triangle. You can use these masks to set the flags parameter.
#define kQATriFlags_None 0
#define kQATriFlags_Backfacing (1 << 0)
Constant descriptions
- kQATriFlags_None
- Pass this value for no triangle flags. The triangle is frontfacing or has an unspecified orientation.
- kQATriFlags_Backfacing
- The triangle is backfacing. You should set this bit for all triangles known to be backfacing (to help the drawing engine resolve ambiguous hidden surface removal situations).
