I am working on creating a 360° virtual tour where panoramic images should seamlessly integrated with a 3D model.
Here’s the workflow: The user clicks a hotspot.(PRESS m key) The camera moves to the hotspot's position in the 3D model. The view switches to a spherical panorama view where the user can freely rotate the camera in 360 degrees.
My requirement I want panorama image overlay on 3d model correctly.
What I have done
Created a sphere and applied texture(panorama image on that sphere) Sphere position set at hotspot position as this the place where panorama was capture.
function createSphereAndLoadPano() {
let texturePath = 'https://i.imgur.com/wJeAbfa.jpeg';
const textureLoader = new THREE.TextureLoader();
const panoramaTexture = textureLoader.load(texturePath);
const panoMaterial = new THREE.MeshBasicMaterial({ map: panoramaTexture });
const sphereGeometry = new THREE.SphereGeometry(500, 60, 40);
sphereGeometry.scale(-1, 1, 1);
const panoSphere = new THREE.Mesh(sphereGeometry, panoMaterial);
panoSphere.up.set(0, 0, 1);
panoSphere.rotateX(Math.PI / 2);
let rad = THREE.MathUtils.degToRad(90);
panoSphere.rotateY(rad);
let vecPos = new THREE.Vector3(101.02, 97.17, 4.35);
panoSphere.position.copy(vecPos);
scene.add(panoSphere);
}
Here’s the live demo :Demo Press m key to move and activate the pano mode.
I have done hardcoded manipulation to rotate the sphere to set alignment but this does not work well
I want to know.
What are the standard techniques and considerations for accurately aligning 360° panoramic images with a 3D model at specific hotspot locations in a virtual tour?
