[color=#000000][font=Verdana, Arial, Helvetica, sans-serif][size=2]I have to implement this method on Page 42

[url="http://www.global-edge.titech.ac.jp/faculty/hamid/courses/shapeAnalysis/files/2.BasicNotions.pdf"]http://www.global-edge.titech.ac.jp/faculty/hamid/courses/shapeAnalysis/files/2.BasicNotions.pdf[/url]

Here is the dataset :

Dragon dataset of [url="http://graphics.im.ntu.edu.tw/~robin/courses/cg03/model/"]http://graphics.im.ntu.edu.tw/~robin/courses/cg03/model/[/url]

The output should look like Page 44 on above pdf file.

I am having problem to code it in C++. Can anyone code it for me in C++ or provide some psedocode for me to start. Any help appreciated! Thanks!

That pdf file only gives a general description of the method. I suggest reading the references at page 47 to learn more about the technique.

Yes, I read through those references. I am not good in maths so was not able to understand much. I see same formulae that's there on slides the same is there in those references! could not get much help. I thought people here would be able to relate to this methods and could help me better.

Thanks!

What do you not understand about those formulas? Do you not understand differential geometry quantities like the tangent space, normals, curvatures, first and second fundamental forms...? Do you not understand the numerical methods used to locally approximate the surface (ie. how to minimize the MLS error)? Do you not understand how to apply all those concepts in the discrete triangular mesh case?
