    Hi,

    i want to show/hide an html-element dependent on wheter an 3D-object is currently obscured or not. Similar to the functionality of annotations.
    It should be so that the html-element is shown/hidden in realtime when the 3D-Scene is rotated by the user and specific objects of that scene are obscured / not obscured.

    Is there a simple way to do that?

    I tried doing so with the “is visible -Puzzle” but cant get it to work.

    Thanks a lot.
    J :bye:

    hi,

    you can probably employ the raycast puzzle for this purpose

    Hi Yuri,

    thanks for your answer. I tried using the raycast-puzzle but i cant really wrap my head around how to make it work. Do you have any hint?

    Currently my puzzle looks like this: (see attatched screenshot)

    I want to send a ray from the camera in the direction of a specific object (in this case “Empty_Display”). When the first object in the list is the object “Empty_Display” this means that it is visible, if it is not it means it must be obscured by something else. Thats my thinking so far.

    It works when i use the cameras direction however i cant manage to send the ray in the direction of a specific object. But that would be neccesary to duplicate the final puzzle and check for each object in scene wheter it is obscured or not.

    So my question is: How can i send a ray from camera in the direction of a specific object?

    (in the final app i want to have the functionality as in the oppo find x2 example thats made with v3d: https://www.oppo.com/de/events/find-x2-pro-vodafone/ )
