We propose a new coating for light projection on transparent materials that can open new possibilities for design. What we often struggle with is the lighting of clear glass. By definition, clear glass lets most of the light pass through. We have found a way to turn glass surfaces opaque or transparent by using ultraviolet (UV) fluorescence coating. In combination with a UVA light source, we can project the dynamic content onto a glass surface treated with a special coating that transforms the UVA light into visible light. The added benefit of such a coating is that it can be applied to any organically shaped surface using a spray gun, not just flat surfaces. Another advantage is that the light source is nearly invisible to the human eye, especially with a UV light pass-through filter. We have created a prototype with a modified overhead projector to measure the light characteristics and documented the steps to reproduce our results.

One of the challenges that museums often face is how to present their ‚treasures‘ in a form that is both comprehensive and relevant to today‘s audiences. Digital content alone is not enough in this context and 3D content is increasingly gaining importance. One of the most accessible and at the same time most effective 3D digitisation methods is photogrammetry. The result, if procedures are followed correctly, is not only high-quality content with a wide range of uses, but also potential stepping stones for effective business models. This can reduce acquisition costs quite significantly and make 3D digitisation accessible to a wider range of institutions.

Interdisciplinary research combines computer vision with stage light design to automatically detect light fixtures’ positions to create light animations. Multiple programmable light fixtures are often used in theaters, the event industry, and interactive installations. When creating complex animations such as a wave traveling from one side to the other through multiple light fixtures array, all lights’ positions must be known beforehand. Traditionally the position of the light is marked in the technical plan. However, technicians make mistakes during the installation and sometimes install the light in a different position. In such a case, time-consuming troubleshooting is needed to determine which light is misplaced and either correct the position in the software or manually move the light to the correct position. Our system saves time during installation and produces a light id and position pairs that users can use in various lighting control software. As a result, users can improvise and change the light positions more intuitively without needing a technical plan. Our system saves installation costs and enables rapid prototyping of light shows to create previously impossible organic designs. We verified the system in a controlled experiment and measured the influence of camera resolution on accuracy.
