arc interpolation and line interpolation code

Hello everyone. I want to know where to find the code for arc interpolation and line interpolation for LinuxCNC.

Maybe I'm stupid. I can't find it in github, and I can't find it in LinuxCNC documents.

So I want your help.

its a internal interpreter c-code
it depends on the iso 9axis coordination kinetics to interpolar to the lines in arc only 3 joints are alowed without special kins

very good.
Great. I'd love to take a look at C code,. I'd like to learn more about this interpolation algorithm. Can you tell me where he is? I'm in "LinuxCNC version 2.8.0-pre1-5088-g9f20624 24.4.2. Interp "found some C + code. Do you know where I can find more information?


thanks

Work your way through the src/emc folder in git hub.

This page might also help understand the folders but its all a bit scary...
linuxcnc.org/docs/devel/html/code/code-notes.html

I've already seen this. I'm a little confused. I can't find the main function in it. Maybe it'll take more time.


thanks

I spent some time in there ages ago but have forgotten what I learnt.

Don't hold this as gospel, but my take was one section parses and tokenises the gcode into a buffer then there is another section which processes the buffer and messages are sent to and fro other modules. Basiclaly each section is walled of from the others so it is confusing.

github.com/LinuxCNC/linuxcnc/blob/master/src/emc/tp/tp.c#L1981

Maybe?

thanks
