projective_geometry_playground
the Projective Geometry Playground is a web based application to do experiments with mathematical projections of images.The projective geometry playground runs offline in browser and learner can define a projection as mathematical mapping and visualized the result in HTML canvas. This allows visual debugging of mathamtical mapping.

csv2wikichart_app
"Wikipedia and Wikiversity have templates for creating a graphs/diagram based on data. The benefit of data driven dynamic graphs is that the mathematical curves can be updated much easier. The concept of this repository was developed during COVID-19. Considering this example the number of cases is updated on a daily basis. Updating the image in WikiCommons on a daily basis is consuming much more space for versioning and an update justs adds one additional (x,y) value pair to the chart. The development of this AppLSAC is part of a Wikiveristy learning resource about AppLSAC WebApps https://en.wikiversity.org/wiki/AppLSAC/JSON2Schema and it is build on the JSON Editor of Jeremy Dorn.

aframe360navigation
This repository applies link traversal concept on 360 degree images. As 360 degree images 4 images of the river Rhine close to Cologne/Rodenkirchen in Germany was used to create the aframe 360 degree navigation example. The objective of this repository is to provide a basic example for Wikiversity learning resource for 3D modelling. The link traversal approach runs offline in a browser. For creating your 360 degree image you can use Hugin or e.g. specific dual fish eye cameras. See repository HuginSample, Wikiversity Learning Resource about 3D modelling and Aframe.
