IntersectionPoint2D, IntersectionPoint3D

Create a data set that enables the evaluation of expressions at the intersection points of particle or ray trajectories and a curve or surface. These data sets can use a Ray or Particle data set as their input.

Syntax

model.result().dataset().create(<dtag>,"InsterSectionPoint3D");

model.result().dataset(<dtag>).set(property, <value>);

Description

model.result().dataset().create(<dtag>,"IntersectionPoint2D") creates an intersection point 2D data set with the name <dtag>.

The following properties are available:

Table 7-41: Valid Property/Value Pairs for Intersection Point 2D and Intersection Point 3D Data Sets
Property	Value	Default	Description
axis	double array	{0, 1}	Axis direction for a semicircle used as the curve type or a hemisphere used as the plane type.
bounded	on \| off	on	Control if a line used as the curve type should be bounded by the points or not.
center	double array	{0, 0,}	Center coordinates for a circle, semicircle, sphere, or hemisphere as the curve or plane type.
data	none \| data set name	First compatible data set	The data set this feature refers to.
expr	String		Expression for a general curve or plane.
genparaactive	on \| off	off	Decides if parallel lines or planes should be drawn.
genparadist	double array	{}	Active when genparaactive is on, this property contains the distances from the extra parallel lines or planes to the base plane.
genmethod	threepoint \| pointnormal	threepoint	Active when planetype equals general, this property indicates whether the plane should be specified by three points or through one point and a normal.
genpoints	double	0 or 1, depending on index position ([0, 0, 0; 1 0 0; 0 1 0])	Active when method equals threepoint, this property contains the coordinates of the three points in the rows of the matrix. See below for the use of this property and the setIndex method.
genpnpoint	String array of length three	Zero string vector	Active when genmethod equals pointnormal, this property contains the coordinates of the point.
genpnvec	String array of length three	Zero string vector	Active when genmethod equals pointnormal, this property contains the normal vector.
normal	String array of length two or three	Created from the feature tag.	The names of the variables that can be used to evaluate the curve’s or plane’s normal.
planetype	quick \| general	quick	Specify plane type for the surface type plane (3D).
radius	double	1	Radius for a circle, semicircle, sphere, or hemisphere as the curve or plane type.
quickplane	xy \| yz \| zx \| yx \| zy \| xz	yz	Specify quick plane type. Active when planetype is quick.
quickx	String	"0"	x-coordinate if planetype is yz or zy.
quicky	String	"0"	y-coordinate if planetype is zx or xz.
quickz	String	"0"	z-coordinate if planetype is xy or yx.
spacevars	String array of length 2	Created from the feature tag.	The names of the variables that evaluate to the plane’s parameterization.
type	line \| circle \| semicircle \| general (2D); plane \| sphere \| hemisphere \| general (3D)	line (2D); plane (3D)	The type of curve (2D) or surface (3D).

For specifying the coordinates for a line curve type, for example, use the setIndex method:

model.result().dataset("ip2").setIndex("genpoints", "1.3", 0, 1);

That line sets the y coordinate of point one to the value 1.3.
