    I just checked in VR annotations do not appear.
    Annotations not supported in VR? or is there any specific way to bring them in VR?

    Secondly after pressing a button when it asks you to resume or quit at that screen the annotations are seen floating in space with some reveres linked or something.

    Annotations feature is a great thing actually, especially when customized.

    Html elements are not supported in VR directly. You might consider creating your own object-based system (planes with text).

    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.

    oh thanks I didn’t know this.
    what do you mean exactly by object-based system?
    Popping up 3D planes with texture on them and something like this?

    In that case how is it possible to achieve all the things or effects we get in annotation features?
    Like calling any website content in that floating window? OR showing a video playing in pop up window?

    Why not? You can use CSS3D plugin or HTML mixer.

    Actually both of these have their own issues I believe

    CSS3D I had purchased in the past and the Chinese guy later on stopped its development and also supporting on it. I had reported one bug once he fixed it but later for similar serious bug of underlaying & overlapping he didn’t respond at all. So this plugin I guess that is useless.

    The html mixer however includes almost everything from the CSS3d plugin but for me found it is purely puzzle-less preparation and remains in the 0,0,0 world co-ordinates. do not know how to reposition / reorient and then use it.
    In second case it may be a lack of knowledge or coding knowhow.
    As a non-coder user I feel Verge team could have made this example a little more intuitive and easier to understand.

    The point is that in VR in any case you’ll have to use mesh-based system for annotations :unsure: Even in PCVR and native VR games they use textures on meshes to show text messages or control elements.

    Puzzles and JS. Fast and expensive.

    I will check possibility with html mixer.
    however my query about html mixer as said.

    1. Why it remains absolute center and doesn’t shift with geometry.

    2. Overlapping on geometry as seen in attached image. I tried changing material modes a few times.

    Actually, it does. It can be moved in any direction like other 3D objects in the scene.

    It just remains always visible ))) Annotations should be always visible :unsure:

    OH !
    is it the similar way we move camera in VR instead of direct moving applying with indirect movement?

    This one is not really convincing to stay always visible. If I walk out of a house the TV screen will still be seen through walls. This sounds like a limitation or a unresolved bug.
    If we see the equinox tutorial it shows how to hide annotations when they are going behind to avoid the unnecessary clutter in UI.

    Yes, indeed. Here you can do nothing with CSS3DRenderer :unsure: That’s how it works I suppose. Maybe it’s possible not to render the back side, but the front side will be always visible. But you can use raycasting and show that plane only if no object is between the camera and that plane…

    No. It’s a direct moving of a 3D object. With puzzles.
