how to rotate the camera pose or how to rotate the coordinate.

[DavidCao1993]

thanks for your great jobs. i import cameras.json to add pose. the direction seems right but the rotation seems wrong:


how to solve this problem?

the first pic is the supersplat‘s pic. the second pic is the training pic.

Hi David, not sure. Could you provide the model and cameras.json?

In general, nerfstudio trains with Z-Up while Supersplat expects Y-Up. I already made nerfstudio store the up-axis into the ply-format so supersplat can compensate for this on load. But there was some resistance on the supersplat side. They also don't want to add the up-axis to the ply because there might by some jungle-software that isn't capable of reading those valid ply-files.
Compensating for the reorientation on load would have to be implemented in the engine-core and I don't make PRs there, so without pushing them, nothing will happen :(

i change the data's coordinate. thanks a lot.
