xyzArray Methods

The methods of the xyzArray class are listed below. For a complete list of xyzArray class members, see the xyzArray Members topic.

Public Static (Shared) Methods

FromString You can initialize an xyzArray with a string.
For example: xyzArray A; A= fromString( "{0/0/00; 10/0/0; 10/0/10; 0/10/0}");

Public Instance Methods

Add Adds a point to the xyzArray. Its faster to create an Array by A= new xyzArray(10) and
A[0] = new xyz(1,2,3);
..
A[9] ) new xyz(4,-2, 3);
as
Create an Array of length 0 and add 10 times a point.
ClockWise Indicates the orientation. If the cross vector heads to the same side of the array like the Direction then the result is true, otherwise it is false.
Close Adds a point with same coordinates as the first one
Closed If the first and the last point are equal, it returns true.
copy Creates a copy of the polygon and retrieves it.
cross Calcuates the cross product over all members, which is usefull for calculation of the normal and the area of the array. In case, the polygon is plane cross is a normal, which has the length : 2 * area of the polygon.
Direction Calculates the direction of the polygon in a point, which is described by its param
DistanceOverloaded. This method calculates the distance of the array to a line only in case, if the distance is smaller than MaxDist., otherwise Utils.big will be returned. Imagine a cylinder with radius MaxDist around the polygon. If the line goes through the one of the cylinders, this line will be taken and the distance will be calculated and returned.
Equals (inherited from Object) 
GetEnumerator Implements the method GetEnumerator and returns the IEnumerator of the datafield.
GetHashCode (inherited from Object) 
GetMaxBox Returns an eveloping box of the array relative to a base.
GetPlane Returns a plane, which contains the the first three different points. If they doesn`t exist, null will be returned.
GetType (inherited from Object) 
Invert Inverts the array. The first entry will be the last and so on.
IsConvex Returns true if the array is convex. The Array must be flat.
LengthToParam Converts a given length to a parameter, which can be used as param for the Value-method.
MaxBoxOverloaded. Calculates a environment box with axes parallel to unitbase for the array.
normal Calculates a normalvector of the array. The array must be flat
ParamToLength Calculates the length of the array form 0 until the parameter given by Param. For a Param = Count you get the full length of the array
RemoveAt Removes the Point with a given Index from the Array
RemoveZeros Remove Points, which has a distance zero to the neighbour.
ToArray Returns an Array of xyz
ToString Returns a string, which starts with "{" and ends with "}". The points are separated with ";".
ToxyArray Converts a xyzArray to a xyArray by omitting the z-coordinate
Transform The method transforms every point in the array by the matrix m.
TransformEx The method transforms every point in the array by the matrix m and returns these points in an array.
Triangulation Calculates a Triangulation (also known as tesselation) and returns the triangles in a TriangleList
Value Calculates a point on the polygon belonging to param. For param = 0 , 1, 2, 3 ... you get the points this[0], this[1], this[2], this[3],... For values between a linear interpolation will be done.
xyzArray a = new xyzArray(4);
    a[0]= new xyz(1, 1, 1);
    a[1]= new xyz(1,-1, 2);
    a[2]= new xyz(3, 4, 2);
    a[3]= new xyz(2, 2, 1);
    //a.Value(0.5) = (1, 0, 1.5)
