FAQ
What does 4DV.ai do?
4DV.ai develops technology for creating and distributing 4D video. Its approach uses 4D Gaussian Splatting to represent dynamic scenes in space and time, allowing viewers to explore video from different perspectives. The company focuses on making volumetric and immersive video more practical for applications including entertainment, advertising, sports, fashion, and interactive media.
What is 4D Gaussian Splatting in 4DV.ai?
4D Gaussian Splatting is the underlying technology used by 4DV.ai to represent dynamic visual scenes. Instead of treating video as a flat sequence of images, the approach models spatial information together with changes over time. This allows reconstructed scenes to become interactive and explorable while retaining the motion and visual characteristics of recorded content.
Can 4DV.ai make videos interactive?
Yes. 4DV.ai is designed around the idea of turning conventional visual media into explorable, interactive dynamic spaces. Supporting demonstrations show viewers changing perspectives while experiencing recorded scenes. Rather than restricting viewers to a single fixed camera viewpoint, 4D video provides a more spatial way to experience moving content.
What industries can use 4DV.ai?
4DV.ai identifies film, music videos, sports, fashion shows, and commercials as application areas for its technology. Its underlying 4D video workflow can also support broader immersive-media experiences involving computer vision, computer graphics, AR, VR, and interactive storytelling. The specific implementation depends on the production requirements and intended viewing experience.
Does 4DV.ai support real-time playback?
Real-time playback is an important part of 4DV.ai's technology demonstrations. Its 4D Gaussian Splatting approach is intended to make dynamic reconstructed scenes suitable for interactive viewing rather than only offline rendering. External descriptions of the technology also report real-time scene exploration, including changing viewpoints while the video content continues to represent motion.
Does 4DV.ai require multiple cameras?
4DV.ai has demonstrated multi-camera capture workflows, including a SIGGRAPH presentation involving approximately 20 cameras. However, research associated with the company also explores sparse-view reconstruction, which focuses on reconstructing dynamic 3D humans from limited camera viewpoints. Therefore, capture requirements can depend on the particular workflow, reconstruction method, and production objective.
