Real-time visualization of three-dimensional models in dome spaces provides high immersion and spatial depth without the need for head-mounted displays. Dome environments, already established worldwide as planetariums, offer a unique advantage as they allow multiple participants to share the same immersive space simultaneously. While their traditional role has been astronomy education, there is growing potential to extend their use to broader fields through the integration of digital 3D content.
As part of our recent initiatives, we organized a workshop for planetarians that introduced practical methods of creating and displaying 3D models. The strong interest shown among participants highlighted the need for accessible tools and training opportunities. In response, two software tools were released: "Amateras Model Viewer", a Windows-based application developed by Orihalcon Technologies, and "Hoshizuna: Model Viewer for Dome", a WebGL-based tool designed for real-time operation in a standard web browser. Both tools allow direct dome-master projection of 3D models, requiring only a conventional personal computer connected to a dome system. This lowers the barrier to entry, enabling planetarium operators to experiment with 3D visualization without relying on complex editing workflows or specialized hardware.
These developments suggest new possibilities for using dome spaces in non-astronomical domains, including science communication, education, and cultural heritage. By turning the dome from a site of primarily passive viewing to a more participatory and creative environment, the tools may contribute to professional development and cross-disciplinary collaboration.
In this presentation, we will report on these activities and share preliminary outcomes, while also discussing future challenges and perspectives for expanding the use of real-time 3D models in dome environments.
