Description:
|
This class represents the intersection of a curve (curve1) with another curve (curve2). The intersections are returned as a list. The list can be walked using the "next" member of the class. This class saves the intersection point as
int_point, and saves its corresponding parameter on
curve1 as
param1, and on
curve2 as
param2. The relation between
curve1 and
curve2 at this intersection point are saved as
low_rel, which is the relation on the lower parameter side of the intersection and
high_rel, which is higher parameter side of the intersection with respect to
curve1.

Data:
|
public curve_curve_int *next;
|
|
Pointer to allow linked lists of
curve_curve_ints.
|
|
|
public curve_curve_rel high_rel;
|
|
Relation of curves on the higher-parameter side of
curve1.
|
|
|
public curve_curve_rel low_rel;
|
|
Relation of curves on the lower-parameter side of
curve1.
|
|
|
public curve_curve_userdata *userdata;
|
|
Pointer to an arbitrary object to store user data. If non-NULL, it is deleted when this object is deleted. It is the responsibility of the user's class derived from this to ensure that the destructor does what is necessary.
|
|
|
public double param1;
|
|
Intersection parameter on
curve1.
|
|
|
public double param2;
|
|
Intersection parameter on
curve2.
|
|
|
public logical uv_set;
|
|
TRUE if the surface parameters have been set.
FALSE by default.
|
|
|
public SPApar_pos uv;
|
|
Surface parameters if the curves are known to lie on a surface.
|
|
|
public SPAposition int_point;
|
|
Intersection point.

Destructor:
|
public: curve_curve_int::~curve_curve_int
();
|
|
|
C++ destructor, deleting a
curve_curve_int.
