Infill customisation

I'm working on developing Slic3r infill layers. Specifically from the source code (/Slic3r/xs/src/libslic3r) where the program alternates the infill every 2 layers.

1. Program has to repeatedly print 3 different infill layers until it reaches the last layer (instead of printing alternating angle layers)
2. Each layer consist of 3 different specific angles
3. Each angle is fixed - can be hard coded. (Does not need user input)

The end product will look like the image I have attached, with each color as a different layer.

Does anyone know how to do this?

I will greatly appreciate your help.

Hey all,

I would also love to know whereabouts I could start looking within the source code to try to modify the infill behaviour.

Any help or basic pointers would be most appreciated.

Thanks!
