What is an Add-in?
An Add-in is a component that adds extra features and functionality to an application. It requires minimal memory resources and is used to perform specific task(s). An Add-in is programmed for a specific larger application and acts as a child program after its installation.

WASP 2011 Add-ins
WASP 2011 Add-ins are small components that enhance the capabilities of various modules of WASP3D. Excel, SQL (Store Procedure), Clock and XML are a few examples of WASP 2011 Add-ins.

Scope of Add-ins
1) Local Add-in
The scope of a Local Add-in is limited to a particular scene or template. e.g. Excel, SQL, XML, and User Defined Variables (Integer, String, Float, etc.).
2) Global Add-in
The scope of Global Add-in is set at the engine level, and is available to all scenes and templates.
e.g. Server Variable.

Types of Add-ins
1) DataSet Add-in
A DataSet Add-in is created when the data is in multiple DataTables. The data is stored in the DataSet format and DataTables are displayed. Further to this, the data of each DataTable is displayed in Drone Designer, e.g. Excel Add-in, XML Add-in. Refer to Image 1.



2) DataTable Add-in
A DataTable Add-in is created when the data is in a single DataTable, e.g. Clock Add-in. Refer to Image 2.



3) Variable Add-in
A Variable Add-in is created when there are different data types and that too in variable format, e.g. SGVariable Add-in.
Variable Add-in creates data types as :
String
Integer
Unsigned Int
Float
Float2
Float3
Float4
Color
Boolean

Refer to Image 3.



4) Utility Add-in
A Utility Add-in is created when the data is other than DataSet, DataTable or Variable. e.g Motion Add-in. Refer to Image 4.




Advantages of WASP 2011 Add-ins

• Add-ins extend the functionality of WASP modules like Drone Designer, Sting Server etc. for a SceneGraph.

• Through Add-ins, users can communicate their own data stored in Excel, XML, SQL etc. to Drone Designer, Sting Server etc.

• Users can create Add-ins to access the local as well as the web data, and perform operations on the data.

• An Add-in data can be wired with an Object's parameters, e.g. Sphere → Radius. Refer to Image 5.

• An Add-in data can also be associated with Actions like SetParam, ChangeKeyFrame, MatchVariable, CheckVariable etc. Refer to Image 6.

• User can call Add-in methods and handle the events from the Scene Editor of Drone Designer. Refer to Image 7.
