How to use fitCameraToBoundingBox method? please share some info.

https://cognitedata.github.io/reveal-docs/docs/api/classes/cognite_reveal.DefaultCameraManager

To focus at a clicked object in Reveal, you can do

  1. Get “Point intersection with the object” using Cognite3DViewer.getIntersectionFromPixel(offsetX, offsetY).
  2. Create a bounding box around intersection point like

    const boundingBox = new THREE.Box3();
    boundingBox.setFromCenterAndSize(intersection.point, new THREE.Vector3(1, 1, 1));
  3.  Use this bounding box in Cognite3DViewer.fitCameraToBoundingBox()
    viewer.fitCameraToBoundingBox(boundingBox, 250);

Note that rather than using bounding box directly from the CDF API, it’s recommended to use https://cognitedata.github.io/reveal-docs/docs/api/classes/cognite_reveal.CogniteCadModel#getboundingboxbynodeid to get bounding box for a given node as this accounts for any transformation active on the model.

How to enable and disable mouse click event?

 

The documentation page you referred https://cognitedata.github.io/reveal-docs/docs/examples/click-reactions-cad/ shows how to enable mouse click event “viewer.on(‘click’, callbackFn)”, to disable, unsubscribe the event using “viewer.off(‘click’, callbackFn)”

how to apply 360ImageSet?

 

Hey, seems to be a small bug in our documentation. You need to await the viewer.add360ImageSet(...) method as it returns a promise.

I try to achieve add circle then click rotate camera.

 

I add await but again error comming.



Which version of Reveal are you using? Image360Collection.on(...) was recently introduced in Reveal 4.1.0.
