lookAt method
vector - A world vector to look at.
Rotates the geometry to face a point in space. This is typically done as a one time operation, and not during a loop. Use lookAt for typical real-time mesh usage.
Implementation
BufferGeometry lookAt(Vector3 vector) {
_bufferGeometryobj.lookAt(vector);
_bufferGeometryobj.updateMatrix();
applyMatrix4(_bufferGeometryobj.matrix);
return this;
}
