The code we released is slightly different from the paper on arxiv. Arxiv is a little bit outdated. In the current implementation, we seed only 1 Gaussian - as you said
Features dc and rest relate to the spherical harmonics used to describe the color. We don't go into the details in the paper since it's well described in the original Gaussian splatting paper. For example, this Github issue answers your exact question.
Thanks for your great work! I have two questions.
In the section of Building Sub-maps Progressively, it's said
Where is the corresponding code ? I only saw one gaussian is seeded.
BTW, what does
features_dc
andfeatures_rest
mean in gaussian model? TKS!
