The cube shown has texture coordinates that range from -1 to 2, which forces the texture wrapping mode to be used for everything but the center tile of the texture.
Experiment with the controls along the bottom to see the effect that the different wrap modes have on the texture.
Let's look at each of the wrap modes and discuss how they work.
This wrap mode rounds any texture coordinates greater than 1 down to 1 and lower than 0 up to 0, "clamping" the values to the 0-1 range. Visually, this has the effect of repeating the border pixels of the texture indefinitely once the coordinates go out of the 0-1 range. Note that this is the only wrapping mode that is compatible with NPOT textures.
