Once a 3D model is sliced against a plane and projected onto it, we get a contour curve at certain height. The contour curve I am generating in this process is made of several line segments in closed loop. Now I want to generate another contour curve with the following characteristics:Each of the line segment of the newly generated inner contour curve must be parallel to the corresponding line segments at the outer contour curve.Each of the parallel line segments on both outer and inner contour curve has an adjacent distance in between and defined by a constant value as shown in the attached picture (green mark) Image Link I need some suggested algorithms to generate it . I hope that I have explained the issue properly. Please do let me know if it is not clear enough.Thanks
