Address Modes

From Tech Artists Wiki

An Address Mode is how a texture sampler reads a texture outside of the 0 to 1 range of texture coordinates. Address Modes can be specified in U, V, and W axes individually.

The following Address Modes are available in Direct3D and OpenGL:

• Border: Takes a specified fill color that surrounds the texture (black by default). Note that when mipmapping, this color will interpolate into the 0-1 space.
• Clamp: Takes the edge pixels, and continues them on
• Mirror: Mirrors the texture
• Wrap: Repeats/tiles the texture
