    Post Need help in - Lines animation - Camera overly line movement/animation

    Hello Qt people,

    I am new to Qt and working on an industrial project with linux based HMI.

    One of the requirement is to do an overlay to the front camera view of machine.

    Like car's parking assistance lines are required to be shown on camera.
    Lines changes angles and shapes based on steering angle feedback.

    Can anybody guide on how to do this lines animation?

    I am attaching an image for reference.

    And see the video link below for line animation examples.
    at 0:55 there is this animation.

    Have you already figured out how to draw the lines in the first place ?
    When you know how to do it then you may do it wrong.
    When you don't know how to do it then it is not that you may do it wrong but you may not do it right.
