Point3d

Point3d struct

Represents the three coordinates of a point in three-dimensional space, using double -precision floating point values.

Namespace: Rhino.Geometry
Point3d: references

Constructors (5)

Point3d(double x, double y, double z)

Initializes a new point by defining the X, Y and Z coordinates.

Point3d(Point3d point)

Initializes a new point by copying coordinates from another point.

Point3d(Point3f point)

Initializes a new point by copying coordinates from a single-precision point.

Point3d(Point4d point)

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 vector)

Initializes a new point by copying coordinates from the components of a vector.

Properties (9)

IsValid

Each coordinate of the point must pass the RhinoMath.IsValidDouble 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.

Gets or sets the X (first) coordinate of this point.

Gets or sets the Y (second) coordinate of this point.

Gets or sets the Z (third) coordinate of this point.

Methods (25)

Add(Point3d point, Vector3d vector)

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 point, Vector3f vector)

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 point1, Point3d point2)

Sums two Point3d instances.
(Provided for languages that do not support operator overloading. You can use the + operator otherwise)

Add(Vector3d vector, Point3d point)

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)

ArePointsCoplanar(IEnumerable<Point3d> points,Double tolerance)

Determines whether a set of points is coplanar within a given tolerance.

CompareTo(Point3d other)

Compares this Point3d with another Point3d .
Component evaluation priority is first X, then Y, then Z.

CullDuplicates(IEnumerable<Point3d> points,Double tolerance)

Removes duplicates in the supplied set of points.

DistanceTo(Point3d other)

Computes the distance between two points.

DistanceToSquared(Point3d other)

Computes the square of the distance between two points.
This method is usually largely faster than DistanceTo().

Divide(Point3d point,Double t)

Divides a Point3d by a number.
(Provided for languages that do not support operator overloading. You can use the / operator otherwise)

EpsilonEquals(Point3d other,Double epsilon)

Check that all values in other are within epsilon of the values in this

Equals(Point3d point)

Determines whether the specified Point3d has the same values as the present point.

Equals(Object obj)

Determines whether the specified object is a Point3d and has the same values as the present point.

FromPoint3f(Point3f point)

Converts a single-precision point in a double-precision point.

GetHashCode()

Computes a hash code for the present point.

Interpolate(Point3d pA, Point3d pB,Double t)

Interpolate between two points.

Multiply(Point3d point,Double t)

Multiplies a Point3d by a number.
(Provided for languages that do not support operator overloading. You can use the * operator otherwise)

Multiply(Double t, Point3d point)

Multiplies a Point3d by a number.
(Provided for languages that do not support operator overloading. You can use the * operator otherwise)

SortAndCullPointList(IEnumerable<Point3d> points,Double minimumDistance)

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 point, Vector3d vector)

Subtracts a vector from a point.
(Provided for languages that do not support operator overloading. You can use the - operator otherwise)

Subtract(Point3d point1, Point3d point2)

Subtracts a point from another 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.

ToString(String format,IFormatProvider formatProvider)

Transform(Transform xform)

Transforms the present point in place. The transformation matrix acts on the left of the point. i.e.,
result = transformation*point

TryParse(String input, out Point3d result)

Converts the string representation of a point to the equivalent Point3d structure.

Operators (16)

Subtracts a vector from a point.

Computes the additive inverse of all coordinates in the point, and returns the new point.

Subtracts a point from another point.

Determines whether two Point3d have different values.

Multiplies a Point3d by a number.

Divides a Point3d by a number.

Sums up a point and a vector, and returns a new point.

Sums two Point3d instances.

Sums up a point and a vector, and returns a new point.

Determines whether the first specified point comes before (has inferior sorting value than) the second point.
Coordinates evaluation priority is first X, then Y, then Z.

Determines whether the first specified point comes before (has inferior sorting value than) the second point, or it is equal to it.
Coordinates evaluation priority is first X, then Y, then Z.

Determines whether two Point3d have equal values.

Determines whether the first specified point comes after (has superior sorting value than) the second point.
Coordinates evaluation priority is first X, then Y, then Z.

Determines whether the first specified point comes after (has superior sorting value than) the second point, or it is equal to it.
Coordinates evaluation priority is first X, then Y, then Z.
