Constants

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).
