Triangle centroid

Hello, do you somebody know any simlpe method how to find the triangle centroid (or geometric barycenter) in 3D?

Thanks a lot,

Tom

Just average all the coordinates. For example, if you have a vector containing x coordinates and a vector containing y coordinates, you can find it in the following manner.

x = rand(3,1); % x-coordinate
y = rand(3,1); % y-coordinate
x_centroid = mean(x);
y_centroid = mean(y);

Hmm, that's very simple :-)

Thanks

hi, have you get the code that can find the barycenter of 3d (stl,ply)?
