High tessellation factor- better perf ?

Recommended Posts

Hi guys, 

I just wanted to know if anyone had experience with better performance when using higher tessellation factor ? Its seems to be my case. What is causing it ?

The tessellation is a feature that basically adds polygons to a mesh, and is managed by the GPU. Using the tessellation, a mesh appears having more polygons than it had originally, thus giving the feeling of more "fidelity".

It is basically the same method that you can apply to a picture to make it larger, by adding extra pixels via interpolation.
Adding more polygons to a mesh does not add detail to that mesh, since details that are not there originally can not be created from nothing; anyway, the tessellation helps make the mesh smoother.

Summary : tesselation is GPU bound and makes mesh “look” like being at a higher resolution...

regards, Gerard
