How to place and rotate potree point cloud ?

[ketourneau]

We try to load many potree point cloud in same view but we got placement problem. We try to place the point clouds after loading them but it seems that bounding box is not updated so point cloud is not rendering correctly. Does anyone know how we can rotate and move point cloud after loading them (or before) with bounding box updated ?

Point clouds are not necessarily georeferenced, we'd like to place them as in the collada example :

                // building coordinate
                const coord = new itowns.Coordinates(
                    'EPSG:4326', 4.2165, 44.844, 1417,
                );

                model.position.copy(coord.as(view.referenceCrs));
                // align up vector with geodesic normal
                model.lookAt(model.position.clone().add(coord.geodesicNormal));
                // user rotate building to align with ortho image
                model.rotateZ(-Math.PI * 0.2);
                model.scale.set(1.2, 1.2, 1.2);

Since this PR is accepted, we now place potree point cloud with parent object3d but we still got some rendering issue.

Point cloud is not correctly rendering (maybe bouding box still not updated ?) : https://demo-hackathon.netlify.app/examples/demo_hackathon_orvault_planarview
