> ## Name

> AddressU - 3D API U texture addressing mode

> ## Usage

> AddressU = int(mode)

> WrapS = int(mode)

> ## Valid Enumerants

> mode: Repeat, Wrap, Clamp, ClampToEdge, ClampToBorder, Border, MirroredRepeat, Mirror, MirrorClamp, MirrorClampToEdge, MirrorClampToBorder, MirrorOnce

> ## Description

> Set the Direct3D u-direction texture wrapping mode. See the D3DSAMP_ADDRESSU sampler state description for DirectX 9.

> Set the wrap parameter for texture coordinate S. See the GL_TEXTURE_WRAP_S description on the OpenGL glTexParameter manual page for details.

> The standard reset callback sets the AddressU or WrapS state to int(Wrap).

> ## Opengl Functionality Requirements

> Clamp, Repeat, Wrap: OpenGL 1.0

> ClampToEdge: OpenGL 1.2

> Border, ClampToBorder: OpenGL 1.3

> Mirror, MirroredRepeat: OpenGL 1.4

> MirrorClamp, MirrorClampToEdge, MirrorClampToBorder, MirrorOnce: support for extension EXT_mirror_clamp.
