how to create an outlined polygon with vector3 coordinates?
I have a set of vector3 coordinates and I use them to draw a polygon in another app, my question is: how can I calculate a second set of coordinates to make it look like the line is outlined.
in the above picture, the blue dots are the vector3s I have and the red dots are the one I need, can anyone help me with an algorithm or formula to calculate them?
thanks
