We are describing the tools in detail, the process of the tool chain and the resulting media. Next, we are discussing the challenges in media production like historical correctness and the consultation of historians. In order to create visual reproducibility we are explaining the detailed text prompts, their limitations and how to cope with resulting errors of the human physiognomy. Finally, we are briefly describing the application of the animated and talking generated historic characters in an immersive interactive WebXR environment. The XR experience is presented in web browsers on smartphones, tablets and XR headsets and the underlying software is based on the open-source framework Aframe. Our paper will describe the process, the results and the limitations in detail. Furthermore, we will provide a flow chart of the tool pipeline with visual examples of these aspects. The animations and voices of the historic characters will be demonstrated in videos of the XR application. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.},

The world of valorization of Cultural Heritage is even more focused on the virtual representation and reconstructions of digital 3D models of monuments and archaeological sites.
