The "3D asset" feature or "3D on floor" feature allows placing 3D objects in Augmented Reality. The 3D model
is automatically placed on an horizontal plane as soon as it is detected. The horizontal plane can be for
example a table or the floor.
This feature allows showing 3D objects in augmented reality without the need of an image trigger.
For unsupported devices, the 3D model won't be displayed in Augmented Reality but the 3D model would be
displayed in preview mode.

Correct object center
When the 3D model is placed on the floor, the origin of the 3D model (x,y,z = 0,0,0) is placed where the
plane is detected.
If the checkbox is unchecked, the position of the 3D object will corresponds to the position defined inside
For instance, it may appear above the floor if the object Y-value is > 0 or with an offset if the object
center is not at X = 0 or Z = 0. This behaviour may be wanted if for instance we want a balloon to be
floating up in the air.
However, most of the time we want that the model stands on the ground and such that its center appears where
the object has been placed. This is automatically done when the checkbox is enabled. The system will then
translate the object on top of the floor and centered. This is often required if the 3D model has not been
explicitely created for being displayed in AR.
Adapt model size
By default, the size of the object in AR will correspond to the size defined in the 3D file. If the 3D file
contains a cube of length 1, the cube will appear with a size of 1 meter in AR.
So, if the 3D file does not correspond to the wanted size, you can set the desired size by giving one of the
wanted dimension in meter.

Tutorial: How to create a new AR experience with 3D assets!
We have introduced a new way to experience 3D models in AR! No more need of image tracking, the 3D model is
automatically placed on the floor or on your table. We present here the steps to follow for creating such
The steps are the following:
Create or download a 3D model, we present here how Sketchfab models can be used.
Create a 3D assets in V-Director
Create a V-Director content
1. Get a 3D model
Sketchfab is a platform listing millions of 3D models. It is a good way to find nice 3D models that can be
Search for a 3D model, for instance search for “tower”. Plenty of results will appear. Not all models
downloadable, you may want to filter the results by showing only the “downloadable” models
Select one of the model
Look at the number of vertices and triangles. It gives you some information about the complexity of the
model. If the model is too big and/or too complex, the download and rendering won’t be optimal on a
Download the 3D model in glTF (v2) format. glTF is a recent 3D file format optimized for
interoperability and the format currently supported for 3D assets in V-Director.
Unzip the files in a folder
2. Create a 3D asset in V-Director
Connect to V-Director
Click “3D” in the left menu
Click “+ Import a new 3D asset”
Drag’n’drop the folder containing the 3D model (the .gltf file and with its textures)
A preview of the 3D model is displayed
You can zoom in/out using the mouse wheel
Click and drag to rotate the camera
Ctrl+Click and drag to move the camera
Click the “Upload” button. The 3D asset is created
If necessary, you can modify its attributes, in particular its name and its size.
If the size is not set, the “intrinsic” size of the 3D model is used. 1 unit in the 3D model will
corresponds to 1 meter when displayed in AR. The grid visible for the preview shows a line every meter.
3. Create a V-Director content
We need now to integrate the 3D asset inside a standard V-Director content. The 3D asset can be integrated to
any type of content (image, GPS or beacon).
For this example, we will create an image content.
In V-Director, go to “My Contents” and create a new image content
Upload the image trigger and go to the editor
For this example, we create a “Text button” that goes to a new scene
In the new scene, we add a new “3D asset”
We search for the asset that we have previously created, select it and click “Load”
The size of the model is retrieved from the 3D asset but can be overridden in the settings
The settings provide an option “Correct object center” that translate the model such that it appears
correctly in on the floor once it has been placed in AR
