[Freesurfer] 回复： Triangular mesh sampling problem

External Email - Use Caution

Dear Bruce, I want to do the following, which source code should we use, and if so, can you send me a connection? We now have high and low resolution images, we want to resample each triangular surface mesh generated from low-resolution data onto the corresponding triangular surface mesh generated from high-resolution data and vice versa as follows: For every vertex in a low-resolution surface mesh we found the closest point on the high-resolution surface mesh (which typically fell within a triangle face of the mesh), and defined a point at that location on the high-resolution surface mesh (subsequently referred to as “sparse” meshes).What should we do to use freesurfer to do the above?

Thank you in advance look forward to your reply yours yujunjie ------------------ 原始邮件 ------------------ 发件人: "Bruce Fischl"fischl@nmr.mgh.harvard.edu; 发送时间: 2018年11月7日(星期三) 凌晨2:42 收件人: "Freesurfer support list"freesurfer@nmr.mgh.harvard.edu;

Hi yujunjie

we have code interenally that will do what you are asking, but no binary, sorry. You could download our source code and try to write your own, although it will be a bit of a project.

Dear FS We now have high and low resolution images, we want to resample each triangular surface mesh generated from low-resolution data onto the corresponding triangular surface mesh generated from high-resolution data and vice versa as follows: For every vertex in a low-resolution surface mesh we found the closest point on the high-resolution surface mesh (which typically fell within a triangle face of the mesh), and defined a point at that location on the high-resolution surface mesh (subsequently referred to as ??sparse?? meshes).What should we do to use freesurfer to do the above?

Thanks in advance
