From my understanding, Geometry contains a javascript object structure of the vertices and faces, while BufferGeometry stores raw WebGL data using Float32Arrays, etc.
Is there a method to convert regular Geometry into BufferGeometry, which is more memory efficient and has fewer objects? For instance, if I generate a new SphereGeometry, is there a straightforward way to convert it into a BufferGeometry?
Please note that this information is specific to versions of three.js before r.125.
The traditional Geometry class is no longer available.
const bufferGeometry = new THREE.BufferGeometry().fromGeometry( geometry );
Update for three.js r.124
