Important Note: A Javascript (“PlayerInit.js”) which is included with the Player product is currently modifying fi ve of
these properties: position, orientation, transform, lockToActor, and showAvatar. Since this Javascript provides camera
control by default, and since there is currently just one camera, it may not be possible to modify these fi ve properties
with any dependable results.

The object’s type. Returns “Camera”.
if (foo.type == ‘Camera’) { ... }

// Place the camera at x=10, y=5, z=-25 in the world
camera = application.getView(0).getCamera(0);
camera.position = Vector(10, 5, -25);
transform
The Transform object representing the combined position and orientation of the camera.
// Smoothly animate between EntryPoints ep1 and ep2
// (including their orientations) over 100 frames:
camera = application.getView(0).getCamera(0);
camera.n = 0;
camera.timestep = function()
{
this.transform = ep1.transform.blend(ep2.transform, this.n++/100);
}
addAnimator(camera);
