The "wrap" texture address mode, identified by the D3DTADDRESS_WRAP member of the D3DTEXTUREADDRESS enumerated type, makes Direct3D repeat the texture on every integer junction. Suppose, for example, your program creates a square primitive and specifies texture coordinates of (0.0,0.0), (0.0,3.0), (3.0,3.0), and (3.0,0.0). Setting the texture addressing mode to D3DTADDRESS_WRAP will result in the texture being applied three times in both the U and V directions. This is illustrated in the following figure.
The effects of this texture address mode are similar to, but distinct from, those of the "mirror" mode. For more information, see About the Mirror Texture Address Mode.
