thank you guys
@jaffasplaffa If you mean the quality of the recording... I use a Panasonic GH4 in 4K, full manual, in a dark environment, a little bit of sharpening in post and export in h264.
@Sputnki For a non continuous scape some lines are drawn twice. A more complex solution would be to blank the z-axis (brightness control) when you draw the duplicated edge. The hard thing with these 3D shapes is to find out the right drawing order of the vertices.
