use dvgo init for the w/ mask setting #4

Thanks for your awesome work. For the w/ mask setting, i noticed that you use density voxel grid instead of sdf voxel grid. Could you explain why?

Hi. For the two-stage Voxurf training, we use the SDF voxel grid for both w/ and w/o mask settings. In w/ mask, specifically, we use an additional step of DVGO initialization (as mentioned in the paper, Sec. 5.1), which helps construct a mask cache for better sampling. The density voxel grid is used in this step for convenience, only for building the mask cache.

I see. Thank you!
