Shiny dataset dataloader

How can I check the given data loader and data format for Shiny dataset ?

In addition, what camera coordinate Shiny dataset use?

For example, x,y,z is (right, up, backward) in NeRF.

Can I use the LLFF loader for Shiny dataset as well?

You might want to check the dataset class

nex-code/utils/mpi_utils.py

Line 28 in e7637f3

class OrbiterDataset(Dataset):

what camera coordinate Shiny dataset use?

unlike NeRF, we use OpenCV convention (right,down,forward)

Can I use the LLFF loader for Shiny dataset as well?

we use a modified LLFF loader and might not be compatible with the original LLFF loader. please be careful.

Thanks a lot for your kind reply!!!

Btw, camera coordinate system of Shiny dataset still makes me little bit confused since original LLFF loader transform the coordinate after load the 'poses_bounds.npy'.

OpenCV convention (right, down, forward) you used is the coordinate system of 'poses_bounds.npy' file in shiny dataset??
For example, if I load the 'poses_bounds.npy' file from '$datasetfolder/cd' directory using following code and extract 3x4 poses, then coordinate system of 'poses' array is (right, down, forward)?
