关于等参数曲线的创建函数

hbd1983

extern int UF_MODL_create_isocurve (
tag_t face_id,
int uv_flag,
double parameter,
double dist_tol,
tag_t ** isocurve_id,
int * isocurve_cnt );

tag_t	face_id	Input	The face identifier.
int	uv_flag	Input	1 = create curve along u isoparameter. 2 = create curve along v isoparameter.
double	parameter	Input	Parameter at which to create the curve.
double	dist_tol	Input	Tolerance value. The tolerance is only used when the input face is foreign or an offset of a non analytic face.
tag_t **	isocurve_id	Output to be freed	Array of isoparametric curve identifiers. You may get multiple curves if the face is trimmed. The allocated arrays must be freed with UF_free().
int *	isocurve_cnt	Output	Number of curves created.

小弟对第三个参数一直 没弄明白

double

parameter

Input

Parameter at which to create the curve.

请高手指点一下
