Question about gaussian calss's parameter

[zcc00210]

Hi! excellent work!
I'm new to this field. About the parameters of gaussian class, i'd like to know the meaning of "_objects_dc", "_features_dc" and "_features_rest".And what is their role?

1. _features_dc and _features_rest are coefficients for spherical harmonics and are used to add view-dependent color effects
2. _objects_ds was added in the gaussian-grouping paper and is used to encode the object id via 16 dimensional vector, which is then mapped to the n_objects(by default=256) dimensional vector
