Fantastic and welcome Laijiren! We do love all things NURBS.

As prior experience working with NURBS is quite a rarity, I'm glad to see
you're interested in working on BRL-CAD. Please do work on your proposal
write-up first, but a great accompanying patch to demonstrate your ability to
work with NURBS structures might be to improve/fix/implement one of our
implicit-to-NURBS conversion functions.
I mentioned in a previous post . I believe ray tracing of primitives converted
to NURBS is wrong/incomplete/missing for: ehy, hyp, revolve; and it's
flawed/buggy for these: tor, extrude, pipe.
Primitives are implemented under the src/librt/primitives folder with one
subfolder per primitive and with the NURBS/BREP conversion functions living in
their own *_brep.cpp file (e.g., src/librt/ehy/ehy_brep.cpp). The "csgbrep"
tool (src/proc-db/csgbrep.cpp) will create an implicit and nurbs version of
most primitives. The "rt" and "mged" tools can be used to visualize them.
Feel free to ask questions if you get lost or stuck.

Looking forward to seeing it!
Cheers!
