Open Educational Resources (OER) form an important basis for free access to educational content and also promote collaboration between scientific and educational institutions. The project addresses the understanding of computer graphics and related areas such as mixed and virtual reality. The OERs developed as part of the project complement traditional educational media such as lecture slides and test-based knowledge reviews with exploratory programs. These exploratory applications enable interactive and playful learning of subject areas in the context of computer graphics. Such a learning environment not only promotes a deeper understanding of theory, but also strengthens motivation to learn and supports independent learning. This project is intended to fascinate and encourage students to immerse themselves in the world of computer graphics and other subject areas and to expand their knowledge in a new way.


Computer Graphics is concerned with the generation and display of images using computers. Learning and understanding computer image generation involves studying the algorithms, techniques, and models used to create, manipulate, and display digital images. This includes topics such as 2D and 3D modeling, rendering, animation, texturing, and lighting.

The difficulties in teaching these processes, in addition to the mathematical and programming fundamentals, are logical problems in linking theoretical principles and their visual impact. These are compounded by a lack of spatial awareness. Traditional teaching methods such as static books or presentation slides do not help here. A promising approach is the use of interactive and playful learning units.

In this project, a team from the universities of Worms and Mainz is developing explorative applications. These learning contents cover a wide range of topics in the field of computer graphics, from basics to complex 3D transformations and rendering processes. In addition, supplementary lecture slides and quizzes are provided, which together with the exploratory applications form Open Educational Resources units (ExGOER). These OER provide easy access to complex three-dimensional concepts by using interactively changeable visual representations to enhance understanding of the underlying theory. At the same time, they are designed to promote learning motivation and support independent learning.


The first step is to develop a Unity-based framework application for the exploratory units. This application provides a basic structure and functionality that serves as a foundation. Based on this, ExGOERs for selected computer graphics topics will be developed. The selection of the topics is done in close coordination between the partners involved. The final ExGOERS will be made available on the OpenEdu-RLP platform at the end of the project.
