Is there a way to load multiple textures onto a sphere?
Can we divide a sphere into n sections in Three.js, texture them individually, and then combine them to render the sphere as a whole?
Instead of loading the entire texture onto the sphere at once, I only want to render the visible parts on the screen. As the user rotates the sphere, the remaining parts of the texture should be loaded.
Using a single image on a sphere seems to distort at the poles. How can this issue be resolved?
Check out this resource for more insight: Instead of creating a sphere from scratch, consider starting with a cube and transforming it into a sphere. Utilizing cube logic on the cube sphere can greatly expedite the process.
var geometry = new THREE.BoxGeometry( 1, 1, 1, 8, 8, 8 );
for ( var i in geometry.vertices ) {
var vertex = geometry.vertices[ i ];
vertex.normalize().multiplyScalar(radius);
}
var materialArray = [];
var faceMaterial = new THREE.MeshLambertMaterial({
color: sphereColor,
transparent: true,
opacity: 0.4
});
for (var i = 0; i < 6; i++) {
materialArray.push(faceMaterial);
}
var material = new THREE.MeshFaceMaterial(materialArray);
var sphere = new THREE.Mesh( geometry, material );
scene.add( sphere );
