Learn Cognite 3D Model
Best answer by Lars Moastuen
To focus at a clicked object in Reveal, you can do
- Get “Point intersection with the object” using Cognite3DViewer.getIntersectionFromPixel(offsetX, offsetY).
-
Create a bounding box around intersection point like
const boundingBox = new THREE.Box3();
boundingBox.setFromCenterAndSize(intersection.point, new THREE.Vector3(1, 1, 1)); - 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 use fitCameraToBoundingBox method? please share some info.

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)”
Hey, seems to be a small bug in our documentation. You need to await the viewer.add360ImageSet(...) method as it returns a promise.
I add await but again error comming.
Which version of Reveal are you using? Image360Collection.on(...) was recently introduced in Reveal 4.1.0.
My version is "@cognite/reveal": "^4.0.0",
Ok, please update the dependency (as yarn.lock / npm.lock may still have 4.0.0 set).
please share sample code.
Documentation covering 360 images can be found here: https://cognitedata.github.io/reveal-docs/docs/examples/image360
1.what is site_id ?
2.how to find site_id?
Documentation about 360 images data is available at https://docs.cognite.com/cdf/3d/guides/360images_upload/, you will find required details related to site_id & more about 360 image data
Unfortunately there are no 360 images available in the demo project currently.
- I would like to know how an Asset id is connected to its respective 3D model
Details of CDF assets with 3D models is available in documentation at https://cognitedata.github.io/reveal-docs/docs/api/classes/cognite_reveal.AssetNodeCollection/
Assets API
https://docs.cognite.com/api/v1/#tag/Assets
3d Model API
https://docs.cognite.com/api/v1/#tag/3D-Models/operation/get3DModels
I have assets id, The Assets id connected to its respective 3d model
Please share Which API I call.
