Vertex Normals on BEM surfaces

Discussions
1

Hello,

I am interested in obtaining the vertex normals (VertNormals) from the BEM surfaces. Concretely, I used BST version 18-Mar-2024 to generate the BEM surfaces and export them into MATLAB. However, the exported struct does not contain the field VertNormals. Is there any way I could obtain the VertNormals variable?

Thank you in advance.

You can use the function tess_normals() (distributed with Brainstorm) to compute the (vertex and face) normals from the surface Vertices and Faces
