title: Three.js camera.rotation.y to 360 degrees conversion
body: <p>I'm trying to rotate a 2D object (in a GTA style minimap overlay) relevant to the Three.js camera rotation.y value in my 3D scene. </p>
  
  <p>The problem is the radians returned from camera.rotation.y value are a bit strange, going from 0 > -1.4 radians through the first 45 degrees, back from -1.4 > 0 radians through to 90 degrees, 0 > 1.4 radians through to 270 degrees, and 1.4 > 0 radians to 360 degrees. </p>
  
  <p>Does anyone know a way to convert or translate these values into 360 coords? </p>
  
  <p>I'm using PerspectiveCamera and OrbitControls. </p>
  
  <p>Thanks in advance! </p>
