How do you determine the correct (2) levels to interpolate between?

RyuK

@meranara That's mentioned in slide 58, if you get a value in between two levels you interpolate, using the bilinearly interpolated values at the adjacent depths

In the future, it would be nice to have more text in this slide. I found it made sense in lecture at a high level, but there is some key content missing that may help with the assignment.

What are the values of fd and 1 - fd?

Lavender

I think the mip-map visualization for level d and level d+1 is nice, but the fd and 1-fd figure is indeed a bit confusing.

@msfernan I believe fd, ft, and fs are the t values in the lerp equation (see slide 28 for more detail). So they are the distance between the two values you are trying to interpolate between (and if you are interpolating between two pixels, one distance will be t and the distance to the other pixel will be 1-t). But yeah, this is pretty confusing imo.
