Point3d Structure |
Namespace: Rhino.Geometry
Assembly: RhinoCommon (in RhinoCommon.dll)
SyntaxThe Point3d type exposes the following members.
Constructors| 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 single-precision point.
|
| Point3d(Point4d) |
Initializes a new point by copying coordinates from a four-dimensional 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.
|
Properties| 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.

(Provided for languages that do not support operator overloading. You can use the + operator otherwise) |
| Add(Point3d, Vector3d) |
Sums up a point and a vector, and returns a new point.
(Provided for languages that do not support operator overloading. You can use the + operator otherwise) |
| Add(Point3d, Vector3f) |

| ArePointsCoplanar |
Determines whether a set of points is coplanar within a given tolerance.
|
| CompareTo |
Compares this Point3d with another Point3d.
Component evaluation priority is first X, then Y, then Z. |
| CullDuplicates |
Removes duplicates in the supplied set of points.
|
| DistanceTo |
Computes the distance between two points.
|
| DistanceToSquared |
Computes the square of the distance between two points.
This method is usually largely faster than DistanceTo(). |
| Divide |
Divides a Point3d by a number.
(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 single-precision point in a double-precision 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.) |
| ToString(String, IFormatProvider) | Formats the value of the current instance using the specified format. |
| Transform |
Transforms the present point in place. The transformation matrix acts on the left of the point. i.e.,
result = transformation*point |
| TryParse |
Converts the string representation of a point to the equivalent Point3d structure.
|
