Jump to: The MouseEvent interface represents events that occur due to the user interacting with a pointing device (such as a mouse). js offers three camera types: 86 // - PerspectiveCamera (perspective projection) 87 // - OrthographicCamera (parallel projection) 88 // - CombinedCamera (allows to switch between perspective / parallel projection 89 // during runtime) 90 // In this example we create a perspective camera. I found a method in class Object3D called 'rotateOnWorldAxis', so I had a try on it but it didn't work, it still rotate on it own space. js/http://stemkoski. In a couple of previous articles I already showed how you can create 3D maps and even use elevation data to create 3D representations of the real world.
