Define mip map levels by coloring different areas of the screen in GLSL

I do not want to bombard this post with code. I have a main file, a fragment shader and a vertex shader file.

Do I need to know the steps I should take to color the screen according to the mipmap level? That is where the loop should go, which requests the mipmap level, and then sets the color accordingly. I do not know where to implement this and how, a simple example would be very grateful.

You must create a texture with a different color for each level, and then get that color in your slices program. This could also be calculated using dFdx(texcoord.x)and dFdy(texcoord.y).

As Tibur said, an easy way to do this is to use a debugging texture that has a different color for each level, as shown here .

Now, if you need to calculate the mipmap level manually (usually this is a floating point value), this is another story as you will need derivatives, but this should put you in the way.
