Light Gaussian with gsplat absgs

[hardikdava]

Hello, is it possible to train a model with a combination of gsplat absgs and light gaussian? Thanks

[yzslab]

Of course. Here is an example config file:

model:
  gaussian:
    optimization:
      densify_grad_threshold: 0.0006
  renderer: internal.renderers.gsplat_renderer.GSPlatRenderer
  absgrad: true
  light_gaussian:
    prune_decay: 0.6
    prune_percent: 0.6
    prune_steps:
      - 16_000
      - 24_000

@yzslab Thanks for the config. It worked! what do you think about integrating your gsplat version of light gaussian to nerfstudio gsplat?

Glad to hear that.

My modifications bring some code redundancies to gsplat. https://github.com/yzslab/gsplat/commit/747f55b003450e6a690b41f6cee0e0548601e1b3 https://github.com/yzslab/gsplat/commit/ca617c5b8012773dbd53442228f65b789a62094f

May be someday when I am willing to write a better version. (Don't expect too much.)
