4DGS Rendering Tool | Supports Mono to Multiple Cameras
IZUTSUYA 4DGS Renderer / 4DGS.jp
From videos captured with a single smartphone to multi-camera recordings. We provide a 4DGS rendering tool that allows you to view moving subjects from 360 degrees.
IZUTSUYA has begun offering a rendering tool for 4D Gaussian Splatting (4DGS). 4DGS is a technology that adds a time axis to 3D Gaussian Splatting (3DGS), allowing for the playback of moving people and spaces from any desired viewpoint. The input supports a wide range of formats, from videos taken with a single fixed smartphone (monocular camera) to data captured simultaneously with multiple cameras. In monocular videos, the renderer infers and complements information about the appearance, orientation, and movement of people throughout the video, even for areas not visible, such as the back. The renderer allows for 360-degree rotation of the viewpoint while playing back the movements of people. It also supports play, pause, frame-by-frame advance, movement to any specific time, background changes, and adjustments for lighting effects. For high-end requests, we also offer a high-precision 4DGS production service using multiple cameras at partner studios. The created 4DGS data can be published directly on our spatial video distribution platform "4DGS.jp."

Applications/Examples of results
【Purpose】 - Recording and publicizing moving individuals in dance, traditional performing arts, stage performances, and skills. - Production for web, commercials, PR videos, short videos for social media, and exhibitions. - Recording changes over time, such as before and after construction or the progress of work. 【Choose the shooting method according to your purpose】 - If you want to start easily, you can use just one smartphone for video. - If higher quality is needed, simultaneous shooting with multiple cameras is available. - If the highest precision is required, shooting with numerous cameras at a partner studio can be arranged. 【Related Services】 - 3D/4D Scanning (izutsuya.io/3dscanning/) - 3DGS Mesh Converter (4dgs.jp)

Company information
IZUTSUYA Inc. digitizes real-world spaces and objects by combining 3D/4D scanning, centered on 3D Gaussian Splatting (3DGS), with AI. We adopted 3DGS in our work early, in 2024, and have recorded buildings, traditional crafts, plants, and even human gestures and dance movements as high-fidelity 3D/4D data. We provide an end-to-end service: capture, data optimization and mesh conversion, and publishing, sales and license management on our own 3D data platform, 3Dasset.io. From digital archiving of cultural heritage and infrastructure inspection DX using LiDAR point clouds and AI, to Location XR experiences that combine places with human movement, we help bring 3D technology into culture, construction, tourism and entertainment. We choose between DSLR cameras, 360-degree cameras, LiDAR and markerless motion capture according to each project, and work with research institutions to field-test new equipment and methods. Please feel free to contact us.
