Evolution or revolution? Some say that hardware tessellation is just another PR technology that is not going to bring anything new to the table. Others are convinced that tessellation implementation is as much of a deal as an introduction of high dynamic range lighting. In this article we are going to look at contemporary Tessellation technology supporting applications, in order to determine how much of a difference it makes and how much GPU computing power you have to sacrifice for it....All in all, a year after its formal acknowledgment, tessellation is still a child that needs guidance and nurturing. With the right parent, a truly astonishing growth can be seen, but only time will tell if in-game tessellation is going to become an adult any time soon. If it does, we are in for a real treat.
