Our method ,[object Object],[object Object],[object Object],[object Object],[object Object]
Input Data ,[object Object],[object Object],[object Object],Example: This is not a closed mesh, but since we are only focusing on one edge of this mesh its ok.
Coordinate Transformation ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]
