How to use this function ?


Documentation says: [sidefx.com]

float primuv(string filename, vector uv0, vector uv1, int pn)


I'm misunderstanding (

This looks like a typo in the doc's.
If you use primarclen(string filename, vector uv0, vector uv1, int pn) it seems to have the right signature but i have no idea how it works Any combination i try of inputs and uv vectors only returns -1.

-b

Try this (it's work for me) :

vector2 u1 = {0,0};
vector2 u2 = {1,0};

f@arc_len = primarclen(@OpInput1,u1,u2,0);

Thanks bonsak,dedeks,

Dedeks, can you share expample scene file. Im get same result as bonsak: always return -1.

Here. Input curve needs to be either Nurbs or Bezier.

-b
