Question about mask_camera

[promesse]

Thanks for work!
I would like to ask what 0 1 stands for in the mask_camera.
If 1 represents the voxel that the camera can observe at the current frame, in 'gts/scene-0362/80d56e801c7e465995bdb116b3e678aa/labels.npz' there are only 98390 voxels.
Is this right or not?
Meanwhile, can mask_camera be used for loss?

Waiting for your reply

1. yes, 1 represents the voxel that the camera can observe at the current frame. For the specific frame, you could visualize the image and corresponding occupancy here so that we could do the sanity check, the number seems reasonable to me.
2. yes mask_camera can be used for loss.
