We apologize that support for equirectangular images is not scheduled for implementation in recent weeks. As an alternative, we suggest the following workaround:
Convert the equirectangular image to 6 or 8 pinhole images.
Use the current pipeline to predict the normal map for the pinhole image.
Undistort the resulting normal map back to the equirectangular format.
Any plans on releasing support for equirectangular image ? @hugoycj @Stable-X
