Hi people,
I have generated an isosurface from matlab. The issue is that few of the triangles generated by the isosurface have very bad aspect ratio. i.e. the three points of some of the triangles are nearly collinear. Refining the data to generate the isosurface does not provide any help.
Could some body guide me how to conrol the aspect ratio of the triangles that define the isosurface.

Here is the code I used:
UnitCellCount=1;
Resolution=100;
[x, y ,z] = ndgrid([0:(1/Resolution):UnitCellCount]...
,[0:(1/Resolution):UnitCellCount],...
[0:(1/Resolution):UnitCellCount]);
t=-(cos(2*pi*x).*sin(2*pi*y)+cos(2*pi*y).*sin(2*pi*z)+cos(2*pi*z).*sin(2*pi*x));
t0=1.35;
fv3=isosurface(x,y,z,t,t0,'noshare');
patch('Vertices',fv3.vertices,'Faces',fv3.faces,'FaceColor','r','EdgeColor','none','FaceAlpha',1);
daspect([1,1,1]);

Hi Sayed, unfortunately there are no built-in Matlab functions that would allow you to regularize your mesh. There is, however, one FEX submission that you could try out. Here is the link:
