Add a new dynamic annotation

In a co-viewing session, you can add dynamic annotations within the 3D Room that anyone can manipulate.

Add a new 3D object or image annotation

On desktop, you can drag and drop 3D object (+thumbnail) and image directly from your hard drive into the web browser window.

Once the loading is finished, the annotation will be directly displayed in the 3D Room, ready to be manipulated.

NB: Note that all images you have added in the Editor are also available to add in the 3D Room (see below how to display the annotation gallery in the 3D Room). Also, all images dropped in your 3D Room will be available in the Editor.

Before importing your annotations, be sure to follow these guidelines:

For 3D object

  • Format needs to be .glb
  • Size should not exceed 35 MB by object
  • Polygon should not exceed 5000 by object
  • For each 3D object, prepare also a thumbnail in either jpg or png format. It is required for upload

For image

  • Png or jpg (optimised for the web)
  • Size should not exceed 10 MB

Add a new video annotation

To add a new video, you need to upload it first in your presentation on the Editor side (Hub or Space participant role is required to access it)

Videos added in the Editor will then be available in the annotation gallery.

Display the annotation gallery

All items added to the 3D Room are automatically added to the annotation gallery. Available as soon as you're in a 3D Room (not in 360 scene), it is divided in 3 categories: Image, Video and 3D object. The method to display it is different depending on your device:

In a VR headset

To add a new annotation in the 3D Room, you need to first display the control panel by clicking with your index on the controller trigger.

Trigger button on Oculus Rift

Once displayed, you can find the button to add a new annotation within the 3D Room in the top center of the control panel (only available for logged-in users).

On desktop

You can find the + button on the left bottom corner of the window (only available for logged-in users).

Edit annotations

For both desktop and VR

If an annotation is unlocked, you can select it and keep the mouse/ trigger pressed to locate it anywhere in the room.

Simple click on any annotations (3D Object, image or video) to display the different options:

  • Lock / Unlock: Only available for logged-in users. Once an annotation is locked, unlogged-users can’t select it and therefore can’t move it
  • Delete: Only available for logged-in users. It deletes the annotation in the room (annotation is still available in the media gallery)
  • Scale up and scale down the annotation at each click.

Specificity in VR

An annotation can be scaled or rotated in VR by keeping pressing the grip button on the controller with your middle finger.

Grip button on Oculus Rift

  • Keep pressing one grip to select a media and rotate it.
  • Keep pressing the two grips simultaneously with both your controllers to scale objects.

You can also select an annotation at distance by pressing the trigger and use the multidirectional stick to bring the object closer or further away


Why can't I see the + button or can’t lock or delete a dynamic annotation?

  • It’s probably because you're not logged-in the experience. Visit and verify if you access your Hub or if you’re invited to login.
  • Double-check that you’re in a co-viewing session, URL should contain “multi=true”. In a solo session you’re only able to view the annotations but not move them.

Where can I find 3D objects?

  • Sketchfab and Google Poly propose a large collection of 3D objects in gltf or glb format. A lot of them are free.
  • Be sure to follow the recommendation regarding size and object complexity before importing your new object in Wonda VR Spaces

How do I convert a gltf into a glb?

How to draw

Drawing is available for everyone joining a co-viewing session, logged-in users or anonymous. Drawings are persistent only for a current session, as soon as there are no more participants in a session, all drawings are erased.

On desktop

You can find the Pen icon on the left bottom corner of the window. . Once in drawing mode, here are the options you have:

In VR headset

To select the pen in the 3D Room and in a 360 Scene, you need to first display the control panel by clicking with your index on the controller trigger.

Once displayed, you can find the button to start drawing in the top center of the control panel

Here are the options you have in drawing mode in VR:
