What is "hardware tessellation"?

post #1 of 5
Thread Starter 
Hi guys.
Simple question. What is hardware tessellation?
I'm really confused about that.
And what is the difference between DX 10 and DX 10.1?

EDIT
What is "JuniperXT"?

Hardware tessellation is just that; hardware that enables or assists with tessellation. Essentially it allows graphics hardware to enhance image quality by increasing the number of polygons used to represent 3D objects on the fly.

JuniperXT represents one of AMD GPU's Series, you can google it and get some introductions.

Tesselation in simple terms is a repeating pattern.

Used in video games, It refers to a pattern used to make surfaces look more detailed without having to model all of the polygons by hand. It has been used for years in grass and other simple foliage. More recently it has been used to replace high polygon models since a unified standard was released with DX11. People often like to think it is the only way to make a game look good, when in fact you could get the same effect with high poly-count models.

JuniperXT is the codename for either the 5770 or 5750, i cant exactly remember which.

EDIT: here is an overly dramaticized example of tesselation in action
