How do I properly use the Snap-Method in the MeshVisual?

  • Hey Elliot,

    That's a nice effect that you're looking for and we already made this is one of our templates.

    If you open the Marker Template.

    In the resources panel you can see there is a prefab called ExplosionEffect, you can drag and drop it under the Image Marker [EDIT_ME] object to see it works automatically.

     

    This is how it works:

    In the Marker Template there is a script called Helper Functions.

    This script is all you need to do a single frame capture using:

     

    getScreenCapture()

    or capture live target using:

     

    getLiveTexture()

    You just need to have that script somewhere in your project file. Then, you can have another script like example below to get the snap from a frame.

     

    // -----JS CODE-----

    // @input Component.MeshVisual surfaceMeshVisual

    // @input Component.ScriptComponent helperFunctions

    var capMeshes = []

    function onLensTurnOn()

    {

        capMeshes[0] = script.surfaceMeshVisual;

       getScreenCapture();

    }

    var turnOnEvent = script.createEvent("TurnOnEvent");

    turnOnEvent.bind(onLensTurnOn); 

    function getScreenCapture()

    {

        if(script.helperFunctions.api.getScreenCapture)

        {

            script.helperFunctions.api.getScreenCapture(capMeshes);

        }

    }
     

     

    In this code you just specify a mesh and then reference to helper function then it will do it on Lens Turn On. Make sure also create the references needed for HelperScript. You can always look at the Marker Template to see how does it works and let me know if you have any questions.

     

    Hope this will help.

    Cheers,

    Amir.
