How to use Multi-Views

Table of contents

Babylon.js is able to render multi views of the same scene.

Active cameras

Basically, a scene has a scene.activeCamera property to define the point of view. But you can also define many active cameras with the following code:



If you want to use many cameras, you will need to specify a viewport for each camera:

camera.viewport = new BABYLON.Viewport(0.5, 0, 0.5, 1.0);
camera2.viewport = new BABYLON.Viewport(0, 0, 0.5, 1.0);

A viewport is defined by the following constructor:

BABYLON.Viewport = function (x, y, width, height);

x, y, width, height are all absolute values (between 0 and 1)

Keep in mind that the canvas is similar to a texture. Its x/y of 0, 0... is in the lower left corner.
