public float Y { get; set; }

Property Value

Type: System.Single

A float value that represents the Y coordinate of a 3D point.

Any point used in custom 3D drawing—which is accomplished using GDI+—must be transformed from X, Y and Z (3D) coordinates into X and Y (2D) coordinates using the TransformPoints method. This method takes an array of Point3D objects as its only parameter. By calling the TransformPoints method, the X and Y property values are changed to reflect the 3-dimensional space.

These new X and Y coordinates are then converted to absolute coordinates by using the GetAbsolutePoint method. They are then used for GDI+ method calls.

A relative Y coordinate can be obtained from an axis value using the ValueToPosition method.
