AR technology facilitates the depiction of 3D models with common smartphones. Simply use the QR code, or click on the image to open a browser-based depiction of the respective chemical structure. The model can be moved, rotated, and changed in size by common swiping gestures. Select the “AR” option (not yet available for all models) in the menu and follow instructions to superimpose the 3D model with your camera’s recording of your surrounding to experience representations of chemical structures in an augmented reality experience.
Usage of haptic cubes for the depictions requires installation of the “Object Viewer” app (iOS, Android, Windows) and a physical “Merge Cube” (available here). Scan the QR code in the right column or enter the provided Object Code within the Object Viewer App to superimpose the respective structure with the physical cube.

All models can also be used for 3D-printing – but typically need support-printing due to “free-hanging” parts. All objects can be downloaded as zip-files by clicking on the name of the object in the list below. To obtain a larger number of objects, or the full set of implemented models, please get in contact.
The site has recently been updated, including some major changes, additions and enhancements. In case of missing or broken links, or requests for additional models or pedagogically changed existing objects, please contact guenther.thiele@ac.uni-freiburg… .
