<orthogonal projection>camera

[EricHunag]

I am currently working on a 2D game,

 

the camera is not moving (locked)... so I need to use <orthographic projection> of the camera,

 

like to that used starling(flash framework).

 

Which camera should I use to achieve this effect in babylonJS?

 

thank`s everyone~

Hi, 

 

try this one:

 

var camera = new BABYLON.FreeCamera("camera1", new BABYLON.Vector3(0, 500, 1), scene);
camera.mode = BABYLON.Camera.ORTHOGRAPHIC_CAMERA;
camera.orthoTop = 500;
camera.orthoBottom = -500;
camera.orthoLeft = -500;
camera.orthoRight = 500;
var ratio = window.innerWidth / window.innerHeight ;
var zoom = camera.orthoTop;
var newWidth = zoom * ratio;
camera.orthoLeft = -Math.abs(newWidth);
camera.orthoRight = newWidth;
camera.orthoBottom = -Math.abs(zoom);
camera.setTarget(new BABYLON.Vector3.Zero());
scene.activeCamera = camera;

Hello, 

 

You can use a freecamera and set an orthographic mode :

var mm = new BABYLON.FreeCamera("minimap", new BABYLON.Vector3(0,100,0), this.game.scene);mm.setTarget(new BABYLON.Vector3(0.1,0.1,0.1));// Activate the orthographic projectionmm.mode = BABYLON.Camera.ORTHOGRAPHIC_CAMERA;//These values are required for using an orthographic mode,// and represents the coordinates of the square containing all the camera view.// this.size is the size of our arenamm.orthoLeft = -this.size/2;mm.orthoRight = this.size/2;mm.orthoTop =  this.size/2;mm.orthoBottom = -this.size/2;
