calculate the surface normal from these points
/youtube/video/NpeYTcS7n-M?t=250

add that triangle normal to each of the vertices
/youtube/video/NpeYTcS7n-M?t=331.569

calculate the vertices bordering the mesh
/youtube/video/NpeYTcS7n-M?t=432.289

create a 2d array of integers representing the different vertex indices
/youtube/video/NpeYTcS7n-M?t=524.26898

add a vector3 array for our boarder vertices
/youtube/video/NpeYTcS7n-M?t=888.59998

initialize our border triangles to a size of 6
/youtube/video/NpeYTcS7n-M?t=991.40997

add it to the boarder vertices array
/youtube/video/NpeYTcS7n-M?t=1071.179

loop through the triangles belonging to the border

adding the triangle normal to the vertex normals
