intepret the depth #8

Open fangli333 opened 8 months ago

fangli333 commented 8 months ago

Hi,

I want to ask what is exact definition of the depth. Is it the z-value depth? or the depth in the camera space after world_to_camera projection?

Many Thanks

Imo it is in camera space, since the depth=p_view.z and p_view is computed by projecting the gaussian into the camera space using the matrices.
