TQADrawTriTexture

A drawing engine may define a method to draw texture-mapped triangles. This method is optional and must be supported only by drawing engines that support texture mapping.

typedef void (*TQADrawTriTexture) ( 
                                   const TQADrawContext *drawContext, 
                                   const TQAVTexture *v0, 
                                   const TQAVTexture *v1, 
                                   const TQAVTexture *v2, 
                                   unsigned long flags);

drawContext

A draw context.

v0

A texture vertex.

v1

A texture vertex.

v2

A texture vertex.

flags

A set of triangle flags. See "Triangle Flags Masks," beginning on page 1-63 for a complete description of the available flags.

DESCRIPTION

Your TQADrawTriTexture function should draw the texture-mapped triangle determined by the three points specified by the v0, v1, and v2 parameters into the draw context specified by the drawContext parameter. The texture used for the mapping is determined by the value of the kQATag_Texture state variable. Features of the triangle are determined by the flags parameter. Currently, this parameter is used to specify an orientation for the triangle.
