Augmented Reality (AR) is an enhanced version of reality where live views of physical real-world environments are augmented with superimposed computer-generated images over a user's view of the real-world, thus enhancing the current perception of reality.
Show a 3D model of some object and how it would fit to a place (augment the given reality).
To cover this scenario, the following API is available in GeneXus:
IsAvailable property
| Type |
Boolean |
| Description |
Indicates if the device supports the 3D models |
PreviewObject method
| Description |
Displays the 3D Model |
| Parameters |
3D object: URL domain |
| Returns |
None |
The file URL can be a local URL (i.e. offline applications), or a remote (http/https) URL. When using remote URLs, the content is downloaded before displaying it.
Supported formats of 3D object
These file formats group all the information needed to represent a 3D model. There are several sites with models available to download, for example, AR Quick Look Gallery or https://poly.google.com/
Event '3D'
&URL3D = !"https://developer.apple.com/augmented-reality/quick-look/models/wateringcan/wateringcan.usdz"
if ARPreview.IsAvailable // Check if device supports 3D models
ARPreview.PreviewObject(&URL3D) // Display the 3D model of the URL
else
msg("Your device doesn't support Augmented Reality")
endif
Endevent
This property is available since GeneXus 16 upgrade 9.
For
Apple, not all 3D models are suitable for this. If a message like "Preview Universal Scene Description (Mobile)" appears in runtime, refer to Adding visual effects in AR Quick look.
