Gaussian Splashing: Dynamic Fluid Synthesis with Gaussian Splatting
CoRR(2024)
摘要
We demonstrate the feasibility of integrating physics-based animations of
solids and fluids with 3D Gaussian Splatting (3DGS) to create novel effects in
virtual scenes reconstructed using 3DGS. Leveraging the coherence of the
Gaussian splatting and position-based dynamics (PBD) in the underlying
representation, we manage rendering, view synthesis, and the dynamics of solids
and fluids in a cohesive manner. Similar to Gaussian shader, we enhance each
Gaussian kernel with an added normal, aligning the kernel's orientation with
the surface normal to refine the PBD simulation. This approach effectively
eliminates spiky noises that arise from rotational deformation in solids. It
also allows us to integrate physically based rendering to augment the dynamic
surface reflections on fluids. Consequently, our framework is capable of
realistically reproducing surface highlights on dynamic fluids and facilitating
interactions between scene objects and fluids from new views. For more
