Can it render poses that have never appeared before? about 4k4d HOT 2 OPEN

Hi @CanYueXiBing, that's an interesting question!
On one hand, 4K4D targets real-time general volumetric video & dynamic view synthesis where any type of motion could be present (like objects held by the human (ENeRF-Outdoor), extremely complex clothes (DNA-Rendering), or a puppy (Neural3DV)). Thus we do not explicit model the human body since it would limit 4K4D's setting and scope.
On the other hand, I do think what you proposed could be an interesting research direction. I'm assuming animating 4K4D would mean binding the geometry and appearance of the points onto a SMPL model (maybe look into SLRF?) or other similar human rigs. In this setting, the general motion of the human in the data should be easily controlled, but the generalization of complex clothes or other hand-held objects could prove quite challenging so I guess it would take some time (maybe not long) for people to achieve this.

I've got it! Thank you very much for your answer!
