I try to write vex function to use in sop-contexts, which will query tangent (for example) from geometry - if current point is associated with some vertex on nurbs curve.
How may I query within vex-function which node is performing vex-code?

Thank you!

UP!

Need help on how to get access to geometry from custom vex function in cvex context. Similar to point() or prim() vex functions.

Thanks!

auto file = static_cast<const char *>(argv); // Filename or Op path
GU_SopQuery qsop;
auto handle = qsop.getDetail(file, -1);
auto gdp = handle.readLock();


I also came across GU_VexGeoInputs in the GU_SopResolver header..however, I could not get that to work.

If anyone knows of a better way I would be very happy
