Properties

	Name	Description
	IsValid	Each coordinate of the point must pass the IsValidSingle(Single) test.
	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) component of the vector.
	Y	Gets or sets the Y (second) component of the vector.
	Z	Gets or sets the Z (third) component of the vector.

Methods

	Name	Description
	Add(Point3f, Point3f)	Adds a point to another point. (Provided for languages that do not support operator overloading. You can use the + operator otherwise)
	Add(Point3f, Vector3f)	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(Vector3f, Point3f)	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)
	CompareTo	Compares this Point3f with another Point3f. Component evaluation priority is first X, then Y, then Z.
	DistanceTo	Computes the distance between two points.
	DistanceToSquared	Computes the squared distance between two points.
	Divide	Divides a point by a factor. (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 System.Object is a Point3f and has the same values as the present point. (Overrides ValueTypeEquals(Object).)
	Equals(Point3f)	Determines whether the specified Point3f has the same values as the present point.
	GetHashCode	Computes a hash code for the present point. (Overrides ValueTypeGetHashCode.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	Multiply(Point3f, Single)	Multiplies a point by a factor. (Provided for languages that do not support operator overloading. You can use the * operator otherwise)
	Multiply(Single, Point3f)	Multiplies a point by a factor. (Provided for languages that do not support operator overloading. You can use the * operator otherwise)
	Negate	Computes the additive inverse of all coordinates in the point, and returns the new point. (Provided for languages that do not support operator overloading. You can use the - unary operator otherwise)
	Subtract(Point3f, Point3f)	Subtracts a point from another point. (Provided for languages that do not support operator overloading. You can use the - operator otherwise)
	Subtract(Point3f, Vector3f)	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

Operators

	Name	Description
	Addition(Point3f, Point3f)	Adds a point to another point.
	Addition(Vector3f, Point3f)	Sums up a point and a vector, and returns a new point.
	Division	Divides a point by a factor.
	Equality	Determines whether two points have equal values.
	(Point3d to Point3f)	Converts a double-precision point in a single-precision point. Needs explicit casting to help retain precision.
	(Point3f to Vector3f)	Converts a single-precision point in a single-precision vector. Needs explicit casting to help retain precision.
	GreaterThan	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.
	GreaterThanOrEqual	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.
	Inequality	Determines whether two points have different values.
	LessThan	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.
	LessThanOrEqual	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.
	Multiply(Point3f, Single)	Multiplies a point by a factor.
	Multiply(Single, Point3f)	Multiplies a point by a factor.
	Subtraction(Point3f, Point3f)	Subtracts a point from another point.
	Subtraction(Point3f, Vector3f)	Subtracts a vector from a point.
	UnaryNegation	Computes the additive inverse of all coordinates in the point, and returns the new point.
