D3DX_NORMALMAP

Normal maps generation constants.

#define	Description
D3DX_NORMALMAP_MIRROR_U	Indicates that pixels off the edge of the texture on the u-axis should be mirrored, not wrapped.
D3DX_NORMALMAP_MIRROR_V	Indicates that pixels off the edge of the texture on the v-axis should be mirrored, not wrapped.
D3DX_NORMALMAP_MIRROR	Same as specifying D3DX_NORMALMAP_MIRROR_U \| D3DX_NORMALMAP_MIRROR_V.
D3DX_NORMALMAP_INVERTSIGN	Inverts the direction of each normal.
D3DX_NORMALMAP_COMPUTE_OCCLUSION	Computes the per-pixel occlusion term and encodes it into the alpha. An alpha of 1 means that the pixel is not obscured in any way, and an alpha of 0 means that the pixel is completely obscured.
