A 3D ray that begins at a point and extends infinitely along a line in one direction only.
Use the ISupportErrorInfo method InterfaceSupportsErrorInfo to determine if the object supports extended error information. If the object supports extended error info, VC++ developers should use the OLE/COM IErrorInfo interface to access the ErrorInfo object. Visual Basic developers should use the global error object Err to retrieve this extended error information.
|IClone (esriSystem)||Provides access to members that control cloning of objects.|
|IGeometry||Provides access to members that describe properties and behavior of all geometric objects.|
|IRay||Provides access to 3D Ray properties and methods. A ray has one endpoint (its origin) and continues infinitely in one direction.|
|IRay2||Provides access to 3D Ray properties and methods. A ray has one endpoint (its origin) and continues infinitely in one direction.|
|ISupportErrorInfo||Indicates whether a specific interface can return Automation error objects.|
