camera animation in depthmap/OBJ scene in VR, how to simulate fov in VR?

Hi,

I have a depthmap scene with an obj file where the camera is animated and the object is viewed from different angles.
the position of the camera in space is defined by viewx, viewy,viewz, viewoz, and a fov value. The view direction is defined by a hotspot.
In non vr mode this works well:

const spot=krpano.get('hotspot[spottolookat]');
const camerapoint={viewx:0, viewy:0, viewz:0, viewoz:0, fov:90};

krpano.actions.lookto(spot.hlookat, spot.vlookat, camerapoint.fov, 'tween(default,1)', true, false);
krpano.actions.tween('view.tx|view.ty|view.tz|view.oz', [ camerapoint.viewtx, camerapoint.viewty, camerapoint.viewtz, camerapoint.viewoz ].join('|'), 0.8, 'linear', () => {
console.log('end of animation');
});

Now I want to create exact same animation in VR mode. The problem: how can I set (or simulate) the field of view "fov" in VR mode? I already experimented with the "plugin[webvr].zoom" value, unfortunately without success:

krpano.actions.tween('view.tx|view.ty|view.tz|view.oz', [ camerapoint.viewtx, camerapoint.viewty, camerapoint.viewtz, camerapoint.viewoz ].join('|'), 0.8, 'linear', () => {
// krpano.call('plugin[webvr].zoom(' + 3 + ')');
krpano.call('plugin[webvr].lookat(' + spot.hotspot.hlookat + ')');
console.log('end of animation');
});

Is there an easy way to change the field of view in VR, e.g. by calculating a new viewpoint tx,ty,tz for the camera?

Thanks for any hints in the right direction!

we can set a value to hlookat with plugin[webvr].lookat(). Is there a way to tween/animate this value, or simulate a tween? any idea?

thanks i will have a look!

A part of motion sickness , it is not possible in krpano to animate the camera (the view) freely in VR space like in three or babylon?
So the only possibility would be to animate the rotation/scale of the 3D object itself, is that right?

Hi kme,
thanks, with controllers yes, but how is a smooth animation possible without controllers?
i also tried your annotaion plugin, and it works great on the desktop! Do you have an example that works in VR?
regards

You are not the first to ask about it, so I might have a look at making it VR compatible. right now, the dots are working in VR, but not the information panel.

thanks kme, that would be great!
