Tessellation Shaders - Graphics Shaders - page 351

Figure 13.25. A patern of Moorish tiles that creates a plane-covering tessellation.
Apply this patern to a surface tessellation like some of the
ones shown in this chapter. Hint: you will need to create
a single repeatable rectangular tile with boundaries that
match up, as in the figure at the right, so that it can be repli-
cated across the surface like this:
Another hint: it's not the GLSL tessellation that you need to worry about.
That doesn't change from the examples. Mostly you need to figure out where
in the whole 5-shader process you determine and assign the proper texture
coordinates.
