Point4d

Point4d struct

Represents the four coordinates of a point in four-dimensional space. The W (fourth) dimension is often considered the weight of the point as seen in 3D space.

Derived Classes:

Namespace: Rhino.Geometry
Point4d: references

Constructors (3)

Point4d(double x, double y, double z, double w)

Initializes a new instance of the Point4d class based on coordinates.

Point4d(Point3d point)

Initializes a new instance of the Point4d class from the coordinates of a point.

Point4d(Point4d point)

Initializes a new point by copying coordinates from another point.

Properties (6)

IsValid

Returns an indication regarding the validity of this point.

Unset

Gets the value of a point with all coordinates set as RhinoMath.UnsetValue.

Gets or sets the W (fourth) coordinate -or weight- of this point.

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 (10)

Add(Point4d point1, Point4d point2)

Sums two Point4d together.
(Provided for languages that do not support operator overloading. You can use the + operator otherwise)

EpsilonEquals(Point4d other, double epsilon)

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

Equals(object obj)

Determines whether the specified System.Object is Point4d and has same coordinates as the present point.

Equals(Point4d point)

Determines whether the specified point has same value as the present point.

GetHashCode()

Computes the hash code for the present point.

Multiply(Point4d point, double d)

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

Subtract(Point4d point1, Point4d point2)

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

ToString()

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

Operators (6)

Subtracts the second point from the first point.

Determines whether two Point4d have different values.

Multiplies two Point4d together, returning the dot (internal) product of the two. This is not the cross product.

Multiplies a point by a number.

Sums two Point4d together.

Determines whether two Point4d have equal values.
