Not sure that's what you mean, but there was recently a paper where they put meshless (e.g. voxel or SDF) geometry in an animated tetrahedral mesh "cage" and then animate the meshless model by animating the mesh cage:

Though this currently isn't compatible with 3DGS if I understand the limitations section correctly.

> Finally, our method operates unordered, limiting its suitability for complex volumetric effects. However, a potential solution lies in sorting the generated intervals for proper blending. This enhancement could improve our approach’s compatibility with various meshless representations, such as radiance fields and volumetric lighting.
