smoothing - help: how to smooth a mesh generated by Marching Cubes in real-time?‏ -

Now I am using the Marching Cubes algorithm for a project (real-time rendering of human teeth from CT images). Here's the rendering result:

You can see that the mesh generated by MC is not so easy. Do you guys know about any real-time smoothing algorithm which is called MC Can be applied to the output? Or, is there a better version of MC which can produce a smooth surface?

Any help would be appreciated!

Pls note that the smoothing algorithm should be fast, for subsequent re-calculation of iosurfes during interactive deformation, I have to use MC at about 30 Hz.

is a good algorithm that gives very good results for smoothing . You can apply it several times.

The algorithm is quite easy to implement.

There is a real time about this, so far I've only implemented it permanently, but - AFAIK - it is absolutely possible to apply it as a geometry shader.

Also used in Blender. It is not based on subdivision (it does not modify the top or face count); It changes the corner just to reduce the angles between the neighboring corners. Again, in real time it should be clearly applied in GLSL.

Both of them can be used together.
