It seems that OpenCSG PNG generation is also non-deterministic. Odd pixels change at the edges on consecutive runs on the same computer. Perhaps it is related to the STL problem. I.e. perhaps the tessellation is non-deterministic and that leads to slightly different jaggies on diagonal lines when the triangles are drawn. -- Sent from: http://forum.openscad.org/

AI is taking over OpenSCAD? lol. I bet it's just a rounding error. Sometimes in INKscape I set exact number say to 65 mm and later after saving file it's 64.99998 or something like that. Maybe OpenSCAD Preview cam has same type of error. On 6/10/19, nophead <nop.head@gmail.com> wrote: > It seems that OpenCSG PNG generation is also non-deterministic.

This is being run from the command line by a Python script so all the numbers should be exactly the same each run, including the camera setting.
