tool path planning - zigzag - reprap java software

Hi,

I’m studying RepRap Java source code. I found that reprap generates a zig-zag toolpath for filling areas, but I’m not founding where in reprap’s java code this operation is executed.

My questions are:
- Can anyone send-me more references of this implementation?
- Zig-zag toolpath is the only method for path filling or there is other methods?

And the last question is:
- As all algorithms it has: | input -> processing -> output |
- Anyone knows what are needed as data input to process the algorithm? (Ex: Line Segment Array, Point Array, Splines, etc) and what are the output of this algorithm?

Thanks a lot and sorry for my poor English,
Silvio

Have you looked at this page yet?: [reprap.org]

Yes I looked

[reprap.org]

But the documentation for the topic: "Generating cross-hatch infill" does not exists or it isn't actualized.

Anyone have another suggestion?

Thanks,
Silvio
