How can I get mesh? #396

Open acsgn95 opened 1 year ago

acsgn95 commented 1 year ago

I want to get mesh. So, actually I want to convert the point_cloud.ply of 3d gaussian splatting output to .glb file. How can I do this?

Sorry that is not in the scope of this research work :(

  1. IN FACT，maybe we need NOT mesh from now, becasue the rendering is very fast, in final using, such as in game, we just need 2D image, in stereo case, we just need consistent 2D images. In a word，maybe the implicit representation likes this GaussPoints in this GaussianSplatting, is the final and unified representation. we can see, the points has meaningful postions and can be used for later editing. yes, you can imagine BIGGER futuer. (This point is very IMPOTANT: the GaussPoints based total solution for pure AI stereo direction, for VR, for game, for stereo movie, ...)

  2. IFF you really need mesh, the extraction logic likes NeRF, the GS and NeRF both are implicit represention. you can write a filed_query function and use mcubes to extract. And lazier way, please refer to DreamGauss or https://github.com/graphdeco-inria/gaussian-splatting/issues/350, the you can run this code with demo data in 1 minute, including mesh-extractio.
