Question about Densification

5

您好，非常感謝您release code，想請問一下我在gaussian_model.py看到你在Densification的時候只考慮了canonical gaussian 的Densification，並沒有考慮deform後的gaussian的Densification，例如下面的連結的code只考慮了canonical gaussian 的scaling，這樣在Densification時是否不太合理呢? https://github.com/hustvl/4DGaussians/blob/master/scene/gaussian_model.py#L448

About update learning rate

1

非常感謝您釋出您的code，想請問一下你們當初不對除了position以外的變數做learning rate schedule是有什麼原因嗎? 如下面這個函式只對gaussian的position 做update learning rate，沒有對其他變數例如scale、rotation做update learning rate。 https://github.com/hbb1/2d-gaussian-splatting/blob/main/scene/gaussian_model.py#L168
