Constants

D3DPATCHEDGE_DISCRETE

Discrete edge style. In discrete mode, you can specify float tessellation but it will be truncated to integers.

D3DPATCHEDGE_CONTINUOUS

Continuous edge style. In continuous mode, tessellation is specified as float values which can be smoothly varied to reduce "popping" artifacts.

Remarks

Note that continuous tessellation produces a completely different tessellation pattern from the discrete one for the same tessellation values (this is more apparent in wire-frame mode). Thus, 4.0 continuous is not the same as 4 discrete.
