AlimerEngine DX11 tessellation

Post by boyamer » Wed Oct 26, 2011 10:28 pm

Hi,
I just wanted to tell you that i've just implemented tessellation support into Alimer engine and Ogre3D too using DX11 (OpenGL is still WIP but will be supported soon) :).
It supports triangle, quad and isoline domain with integer, fractional_even, fractional_odd, and pow2 partitioning.
The engine automatically increases tessellation factor based on camera distance (some king of LOD).
I'm going to port some tutorials from here: http://developer.nvidia.com/nvidia-grap ... 1-direct3d, specially terrain and FFP ocean with compute shaders :)

Hope you like it.

Very interesting,

Is this using the Ogre3D systems purely as the renderer for this engine ?

Tessellation is a great addition to Ogre! Your video looks impressive! :D

Do you have any plans of merge your DX11 changes with the ogre trunk?

Great work!
