d-c-fix Decorator

Following the motto “Imagine never having to imagine anything again”, we have developed the perfect app for the Hornschuch company and its d-c-fix window films.

From now on, users can view the films in their own homes before they buy them by using augmented reality. The window is automatically recognized by the latest AR technology and the film is thus placed in the appropriate size.

An explanatory video specially developed for the app and the display of the steps to be followed, which are visualized via animated icons, facilitate the onboarding of users in the augmented reality scene. Captured images are stored in a dedicated gallery and the slides can be purchased directly via the app.

„We are excited about our app and the project went great! Together with SevenD, we developed an innovative solution to enable virtual testing of our window film via augmented reality.“

Porsche - AR Wizard

The app was created as part of a proof of concept to make it easier for owners of the new “Taycan” electric sports car to get to know their vehicle.

Through the use of certain visually highlighted augmented reality elements, which are displayed directly on the user’s vehicle via their smartphone display, the app supports the user and helps them to playfully explore the new functions of their electric vehicle.

CB-tec neocube

Configure and admire the oven of your dreams in augmented reality? – No problem with the app from CB-tec!

All series and models can be selected directly in AR or in the separate model overview and admired in your own four walls. In addition to a practical display of the models in their original size, the available materials can also be combined individually. In combination with the interaction options in the AR scene, such as moving, rotating or fixed placement, the user gets an impression of the effect of the stove in their own home. This allows (potential) customers to experience their oven even before they order it.

Free and without registration!

With the AR Viewer app, you can easily add your own 3D models locally from your device or via a cloud service to the app and display them in augmented reality (AR). Models can then be scaled, moved and fixed in position on a surface.

AR Viewer – a free AR app for iOS and Android. It can be installed and used for free on both Apple iOS and Android smartphones and tablets.

Questions and answers


The AR Viewer app is available free of charge for iOS (Apple) and Android devices in the App and Play Store. The app can only be used if the device used supports augmented reality.

To use the AR Viewer, a device that supports augmented reality (or ARCore for Android devices and ARKit for Apple devices) is required. 

A list of all AR-enabled devices can be found here: https://developers.google.com/ar/discover/supported-devices

The following file formats are supported on Android: GLTF 2.0/GLB

On iOS, the following file formats are supported: USDZ, OBJ, MTL, GLTF 2.0, SCN, STL, 3DS, FBX

The following formats support textures: 


If the file format used supports textures and they are not displayed in the model in AR Viewer, pay attention to the following:

Texture file names must not contain spaces. Underscores (_) can be used instead of spaces. Umlauts (ä,ö,ü) in the name of the texture file can also cause problems and should be avoided. 

Also the MTL file, which belongs to the OBJ file, should be checked. If “Ka 1.000000 1.000000 1.000000” is specified in the materials, this can lead to problems in the display of the textures. If you delete this line, the materials will be displayed correctly and without white haze.

Models can be loaded into the AR Viewer via cloud services (e.g. iCloud Drive, Dropbox, Google Drive) or from a local storage location on the device through the document picker.

A model file and the associated texture files can be selected and opened individually or as a ZIP file. For the ZIP file, the following applies: All files should be located in the first level in the ZIP archive.

In the AR Viewer app, the models can be imported via the “+” button in the AR view.

If you try to import a model and an error message appears, this can have several causes.

1. wrong file format: Please make sure that you use one of the file formats supported by AR Viewer. Since AR Viewer is an augmented reality tool and not a 3D model (conversion) tool (like Cinema4D or Blender), we only support the default file formats. Feel free to use your 3D tool or one of the many (free) online converters to convert.

2. faulty model file: Please make sure that your model is exported without errors. For your glb/gltf files you can use this page to see if your model was exported correctly: https://gltf-viewer.donmccurdy.com/

In this case, please check the size of your model in advance. If the model is abnormally large (e.g. meters instead of centimeters in reality), the model will be loaded and displayed in the size you specified in the 3D program. This means that you may be standing in the middle of your model and can no longer see it.

If the model is supernaturally small, you may not be able to see it at all at a greater distance from the surface.

In this case, try scaling your model. If this does not bring the desired effect, please check whether your modeled 3D model was created in correct, realistic dimensions and adjust them if necessary.


By pulling apart or pushing together with two fingers on the display, the size of the object can be changed.


By rotating with two fingers on the display, the object can be rotated.


To position the object at a different place on the surface, it must be moved with one finger on the display.

In order to be able to image an object on a vertical surface, this surface must be very rich in structure for successful surface recognition. The AR Viewer is specifically designed for horizontal surface recognition.

In marker recognition, unlike normal surface recognition, the 3D model is only displayed in augmented reality when the marker is detected by the device camera. The model is permanently connected to the marker.

All images and pictures can be used as markers. It is important that the marker image is unique and high-contrast. 

Marker recognition is particularly well suited for displaying a company’s own products in augmented reality in combination with a real advertising medium (e.g. print). Product images, for example in a magazine or on a poster, can be stored as markers in the AR Viewer app and linked to the appropriate model so that (potential) customers can view the products directly in their own environment.

To test the marker detection, we have created a sample marker. If the device camera detects the marker in marker detection mode (preferably printed on a horizontal surface), the model defined for the marker appears on it.

The sample marker is available here: PDF

It is not possible to include your own markers with models in the AR Viewer. Feel free to contact us with your request – you can use the contact form or send an email to hallo@sevend.de.

It is difficult to make a general statement here. The performance of the model depends much more on the number and complexity of the materials and textures. The performance of the device used for the display in augmented reality is also decisive. 

As fist shapes, we would advise: 

Models with up to 100,000 polygons should display fine on all devices.
Models with up to 500,000 polygons should still work fine on most devices.
Models with up to 1,000,000 polygons should still work on at least the newer devices.
Models with over 1,000,000 polygons become problematic even on newer devices.

It is best to test the models directly in the AR Viewer.

After we have received your request, we start with a first detailed discussion about what you want to achieve with the app, who the app should be targeted at and clarify some basic technical details. For the conception, we usually create a common specification sheet, if necessary with first design drafts for individual areas that are needed in addition to the AR Viewer base.

Afterwards, we coordinate internally with our development department to be able to provide you with an offer for your individual app solution. 

After the approval of the offer, we start with the implementation. We regularly provide you with test versions of the app for review via the stores.

Once the app has reached the final stage, our quality assurance department tests all functions with an individual, professional test list on various devices of the supported operating systems (Android/iOS). 

After approval from both sides, the apps are then submitted to the respective store (Apple App Store/Google Play Store) for publication.

How long a project takes depends on many factors and cannot be answered in a general way. The time required depends heavily on the individual requirements of the app. If only the AR Viewer functionality with small individual color and content changes is required, we would give a rough time estimate of 1-2 months.

If additional areas/features are needed in addition to the existing AR Viewer base, this will contribute accordingly to the extension of the project time. Since these adjustments are usually very individual, the effort is also to be estimated individually.

In addition to your own app in the App and/or Play Store, we also offer you the option of using your own model directory within the AR Viewer app – the so-called directory solution.

With the directory solution, we offer you the possibility to make your own models available via the AR Viewer without developing your own app. 

For this purpose, we create a separate directory for you in the AR Viewer app (comparable to the directory of our example models). To access the directory, your target group needs the link (e.g. in the form of a QR code). We share this with you and you can share it as often as you like. The directory remains with the user until they manually remove it. 

Once the user has called the directory, the models stored there are available to them.

Interested in having your own directory in the AR Viewer app? – Great! We are looking forward to your request!
