I have a triangulated patch of a 3D object. I have the matrixes with all the vertixes and faces of my mesh.
Setting a line in the 3D space I would like to obtain the index of which face does my line intersect.
To be more specific:
Using the function Triangle/Ray Intersection (https://ch.mathworks.com/matlabcentral/fileexchange/33073-triangle-ray-intersection) I defined a ray normal to one of my traingles on the mesh. This ray is then intersecting my 3D object in a second triangle. I need to know which triangle is it in my matrix of faces 'f', in order to then compute the thickness of my object as distance of the two faces.
Thank you for any help,
I hope it is clear.
