QADrawTriMeshTexture

You can use the QADrawTriMeshTexture function to draw a texture-mapped triangle mesh.

#define QADrawTriMeshTexture(drawContext,nTriangle,triangles) \
   (drawContext)->drawTriMeshTexture (drawContext,nTriangle,triangles)

drawContext

A draw context.

nTriangle

The number of indexed triangles pointed to by the triangles parameter.

triangles

A pointer to an array of indexed triangles. See "Indexed Triangle Structure" (page 1-80) for a description of indexed triangles.

DESCRIPTION

The QADrawTriMeshTexture function draws the texture-mapped triangle mesh specified by the triangles parameter into the draw context specified by the drawContext parameter. Each triangle in the mesh is defined by a TQAIndexedTriangle data structure, which contains three indices into the array of texture vertices previously submitted to the draw context by a call to the QASubmitVerticesTexture function.

SPECIAL CONSIDERATIONS

QADrawTriMeshTexture operates only on a triangle mesh previously submitted using the QASubmitVerticesTexture function. Use QADrawTriMeshGouraud to draw a triangle mesh submitted using the QASubmitVerticesGouraud function.

The QADrawTriMeshTexture function is optional and must be supported only by drawing engines that support texture mapping.
