    How can I scale and rotate my 3d object in AR mode?

    I would like to use two fingers to scale the 3d object and one finger Drag to rotate the 3d object.

    1. When I drag left the 3d object will turn left.
    2. When I drag right the 3d object will turn right.
    3. When I place two fingers on the screen and spread them apart, I can see the close-up of the 3d object on the screen.
    4. When I place two fingers on the screen and bring them together, I can see the 3d object reduce immediately.

    Note:
    1. Android / Not IOS
    2. Could I have the puzzle code?

    Thanks

    Hi sylc0619,

    You can use the drag puzzles to implement rotating/scaling on mobile. It should work in AR mode too (on Android).

    Make sure you check enable HTML in the enter AR puzzle.

    Hi Yuri
    The problem is that drag puzzle doesn’t recognize gestures.
    So I propose that drag puzzle recognize gestures based on standard V3D control:

    PC
    Rotation (Left Mouse Button)
    Move (Right Mouse Button)
    Zoom (Scroll wheel up/down)

    Mobile
    Rotation (One Finger)
    Move (Two Fingers)
    Zoom (Two fingers move towards and away from each other)

    So based on that drag puzzle (This will also help with AR controls):

    The when dragged over puzzle recognizes only one-finger touch over an object and disables the scene controls while dragging this object. Do not make simple things more complicated. Just add three buttons (move/rotate/scale) and switch between modes

    Puzzles and JS. Fast and expensive.

    If you don’t see the meaning in something it primarily means that you just don’t see it but not the absence of meaning at all.

    I understand, but this means adding three more buttons to the UI for mobile devices where the display is very small and minimizing the UI so that the 3D model is clearly visible is a challenge. Especially in AR

    You may re-work those functions to meet your specific needs. They are clearly visible in visual_logic.js.

    Or you can check the count of touches
