Can a sphere be textured in sections rather than all at once? Just like we can use 6 textures on 6 sides of a cube, is it possible to apply different textures to different parts of a sphere? For example, dividing the sphere into quarters and texturing each quarter with a different texture. Is this achievable with THREE.js or another library?
Appreciate any help on this matter.
To create a sector of a sphere using the SphereGeometry constructor, you can specify various parameters:
THREE.SphereGeometry( radius, widthSegments, heightSegments, phiStart, phiLength, thetaStart, thetaLength )
An effective way to achieve this is by following this approach:
var parent = new THREE.Object3D();
scene.add( parent );
var geometry = new THREE.SphereGeometry( 5, 24, 16, 0 * Math.PI/2, Math.PI/2 );
var material = new THREE.MeshLambertMaterial( { map: texture0 } );
mesh = new THREE.Mesh( geometry, material );
parent.add( mesh );
var geometry = new THREE.SphereGeometry( 5, 24, 16, 1 * Math.PI/2, Math.PI/2 );
var material = new THREE.MeshLambertMaterial( { map: texture1 } );
mesh = new THREE.Mesh( geometry, material );
parent.add( mesh );
var geometry = new THREE.SphereGeometry( 5, 24, 16, 2 * Math.PI/2, Math.PI/2 );
var material = new THREE.MeshLambertMaterial( { map: texture2 } );
mesh = new THREE.Mesh( geometry, material );
parent.add( mesh );
var geometry = new THREE.SphereGeometry( 5, 24, 16, 3 * Math.PI/2, Math.PI/2 );
var material = new THREE.MeshLambertMaterial( { map: texture3 } );
mesh = new THREE.Mesh( geometry, material );
parent.add( mesh );
This code snippet is for three.js version r.63
