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.
