This learning resource was created as Projective Geometry[1] Playground in which learners/students can test a projective mapping with a simple WebApp that runs completely in the browser as runtime environment (see AppLSAC). A browser is available on almost every standard operating system and AppLSAC approach allows that the course content can be shared offline between devices.
This learning resource can be displayed as Wiki2Reveal slides. It meant to be used by teachers, to explain in the classroom how the HTML and Javascript files are organized and how they can be used to explore and test the projective mappings created by students.
The learning resources was created for the Wikiversity learning resource about the equirectangular projection in a way, that the playground provides a infrastructure to start with and the students can focus on the mathematical mapping.
The following aspects of Projective Geometry Playground are considered in detail:
The target group for Projective Geometry Playground of the learning resource
Learning activities address mathematical skills in projective geometry. Nevertheless the Projective Geometry Playground provides the resource as HTML, CSS and Javascript files. So basic Javascript knowledge is required to use the Projective Geometry Playground. The requirements are:
The coordinate system of an image has a different orientation in y-axis. This is shown in the diagram.
Keep this in mind, when you use the coordinate system for your experiments with projections (see also equirectangular projection.
The learning resource about the equirectangular projection provides the foundations to create the an equirectangular image. Start to explore the learning resource to understand, where the equirectangular projection is used and perform the mathematical learning task for the equirectangular projection. At the end of the learning resource, you will have the mathematical function for the coordinate transformation .
The files in Projective Geometry Playground are stored in Git-repository as OER:
You can display this page as Wiki2Reveal slides
The Wiki2Reveal slides were created for the Geometry' and the Link for the Wiki2Reveal Slides was created with the link generator.
