How does the time enters in the EndoNeRF?

yuehaowang commented 1 year ago

The render function receives a parameter frame_time, which will be batched with ray origins and ray directions (L171-172). Then, in the render_rays function, the frame time will be unpacked from the ray batch(L482) and fed into the network (L533).

And how is the time sampled?

yuehaowang commented 1 year ago

The time is sampled evenly among [0, 1]. Check the code here.
