I'm trying to build a generalizable NeRF [e.g., pixelNeRF] where the features are not scene specific but taken from some encoder. I'm trying to use an SPC Field with an...

Subclassing `WispDataset` to, i.e, return a `MultiviewBatch` with additional supervision fields, and applying `SampleRays` transform on top may cause some of the fields to be omitted. For example, in the...

When the background is white what is the interpretation of adding "ray_colors" to "(1-alpha)"? Will this not make the...
