Get array of vector3 from Float32array

Questions
1

Is there any way to convert directly float32array to array of vector3?

2

No. You have to iterate over your instance of Float32Array and create an instance of Vector3 for three subsequent float entries.

function ToVertices(geometry) {
  const positions = geometry.attributes.position;
  const vertices = [];
  for (let index = 0; index < positions.count; index++) {
    vertices.push(
      new THREE.Vector3(
        positions.getX(index),
        positions.getY(index),
        positions.getZ(index)
      )
    );
  }
  return vertices;
}
