Just stumbled across the concept of 4D Gaussian Splatting (4DGS). Needs more reading and investigation. Examples include:
- Luiten, Kopanas, et al. (2023)
- Paper (and code?): https://dynamic3dgaussians.github.io/
- Youtube overview: https://youtu.be/BHe-BYXzoM8?si=2S0Dvq17015jIHzY
- Wu, Ye, et al. (2023)
- GraciaAI - attempting to use the above, making VR more immersive (I think): https://www.gracia.ai/
Really cools constructions including dynamic scenes.
