Green your in- or the outside - enjoy our "AR (Augmented Reality) Progressive Greetings Web App:-)

Hints: After pressing the start button, hold the camera at a slight angle and be patient until the device has scanned the ground and a white ring appears. Then tap the screen to place an object. Get close to things or around the houses or move away to discover the whole scene!

 Best wishes from the su-pa team

PS: Events in 2020 have animated us to realize this experimental "capriccio" (whim). It cheered us up and we hope it works for you, too.

Dominik: To realize this we used the WebXR Device API (w3.org) and Three.js (3D library, threejs.org) which allows AR (Augmented Reality) in the web browser on a smartphone and to mix real life (camera) and virtual objects!  
Additionally it's also still a PWA (Progressive web application, wikipedia.org), so you can install it on your device and use it offline. All paintings & photos (except the roof of the house:) are made by su-pa, "Let it snow" is a Three.js example.

We are planning to use these techniques in a various of (funny) ways in future projects.
This is a simple greeting card for fun and the techniques behind are still at an early stage.


More lovely greetings from su-pa: 2014 2015 2016 2017 2018 2019 2020

LWR tool released

Tool for calculation of the extinguishing water retention volume of warehousesThe first version (beta) of the LWR tool (lwrtool.ch) is released.

We transformed a leaflet (Löschwasser-Rückhaltung, PDF, awel.zh.ch) into a web app conceptualized as a Progressive Web App (PWA). It is a supracantonal tool used for the calculation of the extinguishing water retention volume of warehouses.

The LWR tool (lwrtool.ch) is intentionally reduced to the essential, intuitive and can be used across devices. At the same time it is educational and informative - if required, calculation bases, tables, additional information or tools can be accessed directly.

Install it as an app on your device; use it offline; check necessity of fire water retention; calculate the required fire More...

Green up Zurich - Züri begrünt

Green up Zurich

The first steps towards a "Züri begrünt" web app are being taken using a participatory approach!
Among others, the following questions are in focus:
How can incentives be created to motivate city dwellers to participate and proactively promote the greening of their living and working space?
Which needs are in the foreground?

How can a "Züri begrünt" web app be set up or function so that the feasibility of greening projects is high? How can users be supported on the way to More...
