How to get right vector from forward vector

WebEDIT: You can now get the direction in which the camera is looking like so: var vector = new THREE.Vector3 (); // create once and reuse it! ... camera.getWorldDirection ( vector ); Note: By passing in the vector in which to store the result, the method will not have to instantiate a new THREE.Vector3 every time the method is called. Web4 nov. 2012 · You can achieve this using a dot product. dot (a, b) == a.x*b.x + a.y*b.y can be used to find whether vectors are perpendicular: var dot = a.x*b.x + a.y*b.y if (dot > 0) console.log ("<90 degrees") else if (dot < 0) console.log (">90 degrees") else console.log ("90 degrees") Put another way. dot > 0 tells you if a is "in front of" b.
