Create a 3D model without 3D modeling



Preamble

In this article, we’ll guide you through transforming a real-world object into an optimized 3D model for augmented reality with Visuality — no modeling required!

In the example above, the armchair shown on the right was used as a reference to create the 3D model displayed on the left in augmented reality — all in just a few minutes and without any prior modeling!

Please note that this method is not suitable for all types of objects. Some, especially highly detailed ones, may not render optimally and could require traditional 3D modeling.


Capture of your object

To begin, you need to capture the object you want to turn into a 3D model.

Download the RealityScan Mobile app:


Open the app and follow the instructions to create an account. You'll arrive at this screen:

RealityScan application home screen

Tap the "+" button to reach this screen:

New capture creation menu in RealityScan

Select "Augmented Reality Mode". You are now in camera mode.

Augmented reality camera mode in RealityScan

You'll need to capture photos of the object from every angle, both close-up and from a distance. To improve the quality of the 3D model, follow these guidelines:


  • The device used should have a high-quality camera sensor.
  • La pièce doit être uniformément éclairée, sans zones d'ombre ni contraste marqué.
  • Assurez-vous que les photos soient nettes et que l'objet soit photographié sous tous les angles.
  • Alternate between close-up shots for details and wider shots for the overall shape.
  • Generally, 100 to 150 photos are needed depending on the object’s size.

The quality of the 3D model will directly depend on how well these rules are followed.

Appuyez sur le bouton rouge pour lancer la capture, et déplacez-vous lentement autour de l'objet. Le compteur de photos s'affiche en bas à gauche. Au bout d'un certain temps, un nuage de points apparaîtra. Les zones rouges indiquent les endroits insuffisamment couverts par les photos : concentrez-vous alors sur celles-ci (sans négliger les autres).

Once you’ve taken enough photos, tap the arrow. You’ll reach the following screen:

Analysis in progress of captured photos in RealityScan

An analysis is in progress, with a percentage shown on the right. Once it’s done, click the arrow at the bottom right.

Captured 3D object cropping interface

On this screen, crop the object by adjusting the arrows. Use the handles to refine your selection.

Selection adjustment around the captured object

Once the object is centered, click "Ready to process".

Processing options and Ready to process button in RealityScan

Choose the options shown in the screenshot, then click "Process Project".

3D model generation in progress in RealityScan

Wait a few minutes for the object to be generated, then click on it.

Generated 3D model preview with floor removal option

You’ll see your object rendered. One last step: remove the floor by clicking the button on the far left.

Object cropping to remove floor and surroundings

As before, crop the object to remove its surroundings. Raise the rectangle slightly to remove the floor, then click "Crop".

Finalized 3D model ready for export from RealityScan

Your object is now ready! Click "Export 3D model" to import it into Visuality.


Importing the 3D model into Visuality

Go to your 3D object library then click the "Add Object" button.

Add an Object button in the Visuality 3D library

Sélectionnez l'option "Je possède déjà mon objet en 3D".

Selecting the I already have my 3D object option

Vous arrivez ensuite sur la page d'ajout. Renseignez la description, importez le fichier .zip précédemment exporté dans le champ "RealityScan", puis cliquez sur "Valider".

After validation, you’ll return to your library.

Congratulations, your 3D model is now ready to be viewed in augmented reality!


Augmented reality visualization

Cliquez sur "Visualiser/Partager". Vous arrivez sur la page de partage de l'objet.

Sharing page with web and app viewers

Two viewers are available:

Web Viewer: Accessible via a simple URL, no installation required.

App Viewer: Available via the Android app, ideal for large models and offline use.

Vous pouvez générer un QR code pour chaque visionneuse afin de partager facilement le modèle ou l'intégrer à votre site web.
