Hello,
I have written the script about shapes that are constantly updating in z axis.
The last thing I do not know, how to make a shape between current frame vertexes and previous frame vertexes.
I know,that I have to access prievious xpos[i] and y[pos[i], and draw shape with current one but I cannot find the right solution. Problematic area is marked in red color.
Could your help me? Please:)
