vector2 primuvconvert(string filename, vector2 uv, int prim_num, int mode)
geometry
Строка, указывающая на файл геометрии (например, *.bgeo) для чтения. При запуске внутри Houdini может быть ссылкой op:/путь/до/sop.
uv
Curve coordinates to convert. The function returns the converted coordinates.
prim_num
The primitive number of the curve on which to convert the coordinates.
mode
One of the PRIMUV_space_TO_space constants listed below. You can import the constants from $HFS/houdini/vex/include/math.h.
REAL domain is based on the number of curve segments (0 to nSegments). A segment can hold multiple control points based on the curve degree. UNIT domain is the REAL domain normalized to fit in 0 to 1. UNITLEN domain maps the curve based on its length but normalized (0..1). LEN domain maps the curve based on its length (0..CurveLength).
