    Hi, community!

    I want to develop a component, in widgets or qtquick, that shows a high-density height field. This field must be divided by "pixels" that I must change them dynamically. I have looked at the examples and I see some approximations like Surface3D chart or maybe draw directly on the canvas. But the data I have is a lot, like 5000 x 5000 resolution.

    What's the best approach to this situation?

    The truth is out there

      @oria66 said in Best approach to develop a high-density height field chart...:

      shows a high-density height field

      What is this exactly? Is this a height map of sorts, or something else?

        @kshegunov thanks for your interest. Basically, imagine a grid mesh of 1000x1000 resolution. I want to change the elevation of each vertice. But I reevaluated the real-time requirements and I think that with a Suface plot I will solve my problem.

        The truth is out there
