Point3D Class

.NET Framework 4.6 and 4.5

Represents the coordinates of a three-dimensional (3D) data point. This class is used when performing custom drawing with 3D charts.


Namespace:  System.Windows.Forms.DataVisualization.Charting
Assembly:  System.Windows.Forms.DataVisualization (in System.Windows.Forms.DataVisualization.dll)

public class Point3D

The Point3D type exposes the following members.

Public methodPoint3D()Initializes a new instance of the Point3D class.
Public methodPoint3D(Single, Single, Single)Initializes a new instance of the AnnotationPathPoint class with the specified X, Y and Z coordinates.

Public propertyPointFGets or sets a PointF structure, which stores the X and Y coordinates of a 3D point.
Public propertyXGets or sets the X coordinate of a 3D point.
Public propertyYGets or sets the Y coordinate of a 3D point.
Public propertyZGets or sets the Z coordinate of a 3D point.

Public methodEquals(Object)Determines whether the specified object is equal to the current object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeServes as the default hash function. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

Any point used in custom 3D drawing—which is accomplished using GDI+—must be transformed from relative X, Y and Z (3D) coordinates into relative X and Y (2D) coordinates using the TransformPoints method. By calling TransformPoints, the X and Y-values of the Point3D objects are changed so that they reflect the 3-dimensional space. The new X and Y points can then be used for GDI+ method calls—the Z value is then disregarded—after being changed to absolute pixel coordinates using the GetAbsolutePoint method.

Note that the Z coordinate may be less than zero (located behind a chart area) or greater than 100 (located in front of a chart area).

To both enable 3D charts and work with their styles, use the Area3DStyle property. The Point3D class is not used for 3D styles.
