From: karthik on 28 Jan 2010 21:49 i have a 3d image with x,y and z co-ordinates. how to use smooth3 function the input image which i have has rough edges and corners. after applying smooth3 function,i need a smooth closed and bounded surface.

After you read the help: *You could use ones(6227,1) for the input V *For xi,yi and zi, use MESHGRID which spans from min to max of your input x,y and z values. Choose a step size large enough to keep the size of V reasonable.
