This is a 3-part puzzle. Parts can be solved out of order, but, in the end, parts must be put together in order they appear (1, 2, 3) to solve the whole puzzle.
Parts are independent from each other. There is no need to combine pieces of different parts before every part is solved.
Every part contains a puzzle and its key. You'll have to figure out which is which.

Hint 1:
The keys contain what has already been done.
Partial Answer:
So far I see the shapes represent degrees: 120 240 360 90 180 270 60 120 180. I'm guessing you somehow split each image into Red Green and Blue layers with a filter and then individually rotate only one of the layers the corresponding number of degrees counter-clockwise so that it overlaps revealing something. Use the small white circle to line up the rotated images. Must I go through with all that? If I had to guess, I would say the revealed images are constellations. Or something that can be used for triangulation.
Answer:
The 3 parts combine into みらい (how "future" (未来) in Japanese is pronounced)
How does it work:
Every image is a hirogana character split into 3 parts - red, green and blue channels, each one is third of the image, one 120° sector. In every part these sectors "point" at their corresponding, color coded by geometric shapes, azimuths. How shape encoding works: starting from triangle, which means zero, every additional corner of a shape adds 1. Square means 1, Pentagon means 2 and so on. To see the original character one needs to increase image contrast, then undo the rotation of the sectors accordingly - in other words, make them point back "north" (top of the image).
Part 1:
mi - み. Azimuths - R: 120 G: 240 B: 360.

Notes:
Puzzle was made in Blender (character images) and python (shapes). The lines on the images are sector pointers; what azimuth they are pointing at. This puzzle may have suffered from lack of clues, apologies.

Embarassingly messy, but it was fun :)
