    Hello,

    I wondered if there is any ready to use coordinate system. Talking about one having also negative values.

    It should be possible to draw points in it ... I want to use it as a simulation for a robot.

    If there isn't, how could it be realized the easiest way? Points (of geometric shapes) would be available trough a C++ model.

    Thanks in advance!

      Also have a look at:
      https://forum.qt.io/topic/92510/overlapped-surface3d-and-scatter3d/7
      that illustrates Q3DSurface's addCustomItem() method.

        Thank you very much for your input!

        I am not quite sure if this fits my need. These Scatters go in the right direction.
        But If I want to display also negative values it's still one quadrant.

        Is it possible to make a cartesian coordinate system with scatters? So that x, y and z axis intersect in (0,0,0) and then going into both negative and positive direction?

        Thanks!

          In that case, maybe Qt3D or Qt Canvas 3D? You will need to draw everything yourself then...
