Measure depth at given pixel

[alex-klimov]

What is the recommended way to measure the depth at given pixel?

There is method determine_autofocus_target_from_pixel, which measure median depth around given pixel:

instant-ngp/src/testbed.cu

Line 2320 in 675bf4f

void Testbed::determine_autofocus_target_from_pixel(const Vector2i& focus_pixel) {

This is not precise enough for my task - I need as exact depth at given pixel as trained network can give me.

On latest master, Testbed::determine_autofocus_target_from_pixel is actually pixel-accurate, so you should be able to use it as-is.

Tom, this is brilliant! It works perfectly.

The only question I have is to myself, where did last couple weeks of debugging went and why I didn't ask earlier...
