Digital Archive | CG creation of Himeji Castle from point cloud data captured by drone photography
Reproduced with drone measurement and Unreal Engine. An innovative step in creating a full CG VR and PR video of Himeji Castle.
Set against the backdrop of the World Heritage Site Himeji Castle, we present a full CG video utilizing the latest technology. In this project, we created intricate CG models using point cloud data obtained from drone photography on-site, leveraging Unreal Engine. The point cloud data captured by the drone provides a millimeter-level representation of Himeji Castle's main keep, stone walls, and surrounding landscape, accurately reproducing actual dimensions and shapes in the CG environment. By utilizing Unreal Engine's real-time rendering capabilities, we faithfully reconstructed light, shadow, and texture expressions, enabling a variety of dynamic presentations, including changes from day to night and across the seasons. Furthermore, the produced CG video can also be developed as VR content. The presentation allows for experiences that are difficult to achieve with standard video, such as "a viewpoint from the inside" and "the feeling of historical exploration," anticipating a wide range of applications, including tourism promotion and educational events. This video production symbolizes the fusion of cultural heritage preservation and cutting-edge technology. It aims to connect the value of Himeji Castle to the next generation and contribute to the dissemination of new attractions. As a work that demonstrates the potential of CG and VR in future historical tourism, we confidently recommend it.
