Point3d Structure 
Namespace: Rhino.Geometry
The Point3d type exposes the following members.
Name  Description  

Point3d(Point3d) 
Initializes a new point by copying coordinates from another point.
 
Point3d(Point3f) 
Initializes a new point by copying coordinates from a singleprecision point.
 
Point3d(Point4d) 
Initializes a new point by copying coordinates from a fourdimensional point.
The first three coordinates are divided by the last one.
If the W (fourth) dimension of the input point is zero, then it will be just discarded.
 
Point3d(Vector3d) 
Initializes a new point by copying coordinates from the components of a vector.
 
Point3d(Double, Double, Double) 
Initializes a new point by defining the X, Y and Z coordinates.

Name  Description  

IsValid 
Each coordinate of the point must pass the IsValidDouble(Double) test.
 
Item 
Gets or sets an indexed coordinate of this point.
 
MaximumCoordinate 
Gets the largest (both positive and negative) valid coordinate in this point,
or RhinoMath.UnsetValue if no coordinate is valid.
 
MinimumCoordinate 
Gets the smallest (both positive and negative) coordinate value in this point.
 
Origin 
Gets the value of a point at location 0,0,0.
 
Unset 
Gets the value of a point at location RhinoMath.UnsetValue,RhinoMath.UnsetValue,RhinoMath.UnsetValue.
 
X 
Gets or sets the X (first) coordinate of this point.
 
Y 
Gets or sets the Y (second) coordinate of this point.
 
Z 
Gets or sets the Z (third) coordinate of this point.

ArePointsCoplanar 
Determines whether a set of points is coplanar within a given tolerance.
 
CompareTo 
Compares this Point3d with another Point3d.

This method is usually largely faster than DistanceTo().  
Divide

(Provided for languages that do not support operator overloading. You can use the / operator otherwise)  
EpsilonEquals 
Check that all values in other are within epsilon of the values in this
 
Equals(Object) 
Determines whether the specified Object is a Point3d and has the same values as the present point.
(Overrides ValueTypeEquals(Object).)  
Equals(Point3d) 
Determines whether the specified Point3d has the same values as the present point.
 
FromPoint3f 
Converts a singleprecision point in a doubleprecision point.
 
GetHashCode 
Computes a hash code for the present point.
(Overrides ValueTypeGetHashCode.)  
GetType  Gets the Type of the current instance. (Inherited from Object.)  
Interpolate 
Interpolate between two points.
 
Multiply(Double, Point3d) 
Multiplies a Point3d by a number.
(Provided for languages that do not support operator overloading. You can use the * operator otherwise)  
Multiply(Point3d, Double) 
Multiplies a Point3d by a number.
(Provided for languages that do not support operator overloading. You can use the * operator otherwise)  
SortAndCullPointList 
Orders a set of points so they will be connected in a "reasonable polyline" order.
Also, removes points from the list if their common distance exceeds a specified threshold.  
Subtract(Point3d, Point3d) 
Subtracts a point from another point.
(Provided for languages that do not support operator overloading. You can use the  operator otherwise)  
Subtract(Point3d, Vector3d) 
Subtracts a vector from a point.
(Provided for languages that do not support operator overloading. You can use the  operator otherwise)  
ToString 
Constructs the string representation for the current point.
(Overrides ValueTypeToString.)  
Transform 
Transforms the present point in place. The transformation matrix acts on the left of the point. i.e.,
result = transformation*point
