Creator (ICreator80)

The interface is composed of many methods for creating different objects in a project. When creating an object (using one of the CreateXXX methods) the client gets an interface to the newly created object. The client can then use this returned interface to further control the object (i.e. change its position or its color).

Each object created through the ICreator80 interface has an ID that uniquely identifies it in the TerraExplorer Pro world (the ITerraExplorerObject80 . ID property). This ID can be used by the client to get an interface to that object using the GetObject method of this interface. The client can obtain that ID by either of the following methods:

§ Create the object and store its ID for later use before releasing the object.

§ Find the item if you know its name using IProjectTree80.FindItem.

CreateCommandLineProcessAsync

CreateCommandLineProcessAsync allows the launching of TerraExplorer executable tools such as Make3DML.exe, PyramidTool.exe, and MakeCPT.exe using a TerraExplorer API call.

Due to established security measures, TerraExplorer only allows file path parameter values from specific locations:

§ The Skyline TerraExplorer directory within the user's AppData folder. Type %APPDATA% in Windows Explorer and then navigate to the Skyline\TerraExplorer subfolder to locate the path on your computer. This will often resolve to: “C:\Users\[User Name]\AppData\Roaming\Skyline\TerraExplorer”

§ Files/folders in a location selected by the user, using the OpenFileDialog method.

§ Files used by a TerraExplorer object.

The method executes asynchronously, immediately returning an ICommandLineProcessAsync80 that lets you monitor the progress and success or failure of the command line process.

See "Launching a TerraExplorer Executable Tool" for an example of how this method is implemented.

JavaScript

CommandLine)

ICommandLineProcessAsync80 CreateCommandLineProcessAsync (

string CommandLine)

C++

HRESULT CreateCommandLineProcessAsync (

BSTR CommandLine,

ICommandLineProcessAsync80 ** pICommandLineProcessAsync80)

Parameters

CommandLine

The complete command line string for the tool execution, including the executable's name and any accompanying parameters, e.g., "SLMeshConverter.exe param1 param2".

When passing a file path parameter, this can be any of the following:

· For a file located within the Skyline TerraExplorer directory within the user's AppData folder, pass full path, e.g., "C:\Users\Administrator\AppData\Roaming\Skyline\TerraExplorer\Folder\MyFile.txt"

· For files/folders in a location selected by the user, using the OpenFileDialog method – pass key from the JSON that is returned. This is then replaced by TerraExplorer with the actual path.

· For files/folders where a TerraExplorer object file is located - Pass ${OBJECT_ID} e.g. ${0_123456}

See "Launching a TerraExplorer Executable Tool" for an example of how the JSON key returned by OpenFileDialog is passed to an executable launched using CreateCommandLlineProcessAsync.

Return Value

pICommandLineProcessAsync80

An ICommandLineProcessAsync80 that provides a callback-based mechanism similar to the JavaScript promise and the C# Task object. This enables asynchronous management of the command line process, from process exit, to error outputs and standard outputs (using OnExit, OnStderr, and OnStdout respectively).

Exceptions

See: HRESULT Return Values for a list of possible values returned by the HRESULT.

CreateElevationLayer

Loads an elevation layer into the project. Adding the elevation source uses a set of plugins that support multiple file formats. The coordinates of the source can be passed via the UpperLeftX/Y and LowerRightX/Y parameters. If all four coordinate field values are zero, the coordinate information, if available, is read from the file. If the source file coordinate system is not the same as the MPT file Terrain Coordinate system, you can reproject it using ITerrainRasterLayer80. CoordinateSystem.

For advanced layers, e.g. from WMS and SGS, string parameters must be passed that describe the plugins used to read the files and their persistence strings (InitParam and PlugName). To retrieve these parameter values, add layers of the required types from TerraExplorer GUI, and then call ITerrainRasterLayer.InitParam and ITerrainRasterLayer.PlugName. You can then use the values returned by these properties to create additional advanced layers.

CreateFeatureLayer

CreateFeatureLayer loads a feature layer into the project. A feature layer is a visual representation of a geographic data set like roads, national parks, political boundaries, and rivers using geographic objects such as points, lines, and polygons and optional corresponding annotation objects.

TerraExplorer enables you to load feature layers from remote or local databases. Various file formats are supported through a set of external plug-ins. See “Feature Layer Connection Strings” for a list of the supported connection string values and parameters. You are always connected to the data source (local or remote), and all changes to the feature layers can be saved to the original source file. You can get the latest updates to a layer source by refreshing the layer.

TerraExplorer handles differently layers that are created by loading native feature sources (Shapefiles, GeoPackage, GeoDatabase, PDF or SQLite file files, and all server inputs) and layers that are created by loading non-native feature files (e.g., DXF, ASCII and OpenFlight files). For the former, a layer object containing the geographic objects is created in the Project Tree while for the latter the geographic objects are read and put in the TerraExplorer Project Tree as a Group.

If the source file coordinate system is not the same as the MPT file Terrain Coordinate system, you can reproject it using the IFeatureLayer80.Reproject method.

CreateFeatureLayer only loads a feature layer into the project. If you want to load the new layer on the terrain, use the IFeatureLayer80.Load method.

This method executes synchronously, meaning it returns after the layer is created. If you want to execute asynchronously, use CreateFeatureLayerAsync instead.

JavaScript

CreateFeatureLayer(

layerName,

sConnectionString,

GroupID)

IFeatureLayer80 CreateFeatureLayer(

string layerName,

string sConnectionString,

string GroupID = "")

C++

HRESULT CreateFeatureLayer(

BSTR layerName,

BSTR sConnectionString,

BSTR GroupID,

IFeatureLayer80 ** pILayer)

Parameters

layerName

A string representing the name of the layer.

sConnectionString

Specifies information about the data source and the means of connecting to it. See “Feature Layer Connection Strings” for a list of the supported connection string values and parameters.

GroupID

The Project Tree group in which the layer is created. If it is set to an empty string, the object is created under the root. You can obtain the GroupID by one of the following methods:

· Create the group using IProjectTree80.CreateGroup.

· Find the group, if you know the name, using IProjectTree80.FindItem.

· Traverse the Tree using IProjectTree80 methods such as GetNextItem, until you come to the desired GroupID.

Return Value

pILayer

An IFeatureLayer80, representing the newly created layer. This method executes synchronously, meaning it returns after the layer is created. If you want to execute asynchronously, use CreateFeatureLayerAsync instead.

Exceptions

See: HRESULT Return Values for a list of possible values returned by the HRESULT.

CreateFeatureLayerAsync

CreateFeatureLayerAsync loads a feature layer into the project. A feature layer is a visual representation of a geographic data set like roads, national parks, political boundaries, and rivers using geographic objects such as points, lines, and polygons and optional corresponding annotation objects.

If the source file coordinate system is not the same as the MPT file Terrain Coordinate system, you can reproject it using the IFeatureLayer80.Reproject method.

CreateFeatureLayerAsync only loads a feature layer into the project. If you want to load the new layer on the terrain, use the IFeatureLayer80.Load method.

This method executes asynchronously, immediately returning an ITerraExplorerAsync80, thereby ensuring that control is promptly handed back to the calling function. The results are delivered when ready using the ITerraExplorerAsync80 object that was returned. The ITerraExplorerAsync80 object provides a callback-based mechanism similar to the JavaScript promise and the C# Task that offers the following functionality:

§ Allows for handling rejections/errors and successful resolution of the asynchronous operation (using OnReject and OnResolve).

§ Upon resolution of the query, enables the passing of an IFeatureLayer80, representing the newly created layer, to the OnResolve callback.

If you want to execute synchronously, use CreateFeatureLayer instead.

CreateMessage

Creates a message object that is displayed in a container or floating popup. The message can be a text string, HTML page, image, script code, multiple links or any other file.

You can assign a message to any object, location, and Project Tree message element, or activate one as part of a presentation. You can also assign a message to be displayed at the beginning of the project. The message is triggered when the user clicks on the object in the 3D Window or double-clicks on the Project Tree message element which is associated with that message object. When a message object is triggered, the message content is displayed in the message-defined client.

To create a popup message, use the CreatePopupMessage method.

JavaScript

CreateMessage(

TargetPosition,

msgData,

Type,

BringToFront)

ITerraExplorerMessage80 CreateMessage(

MsgTargetPosition TargetPosition,

string msgData,

MsgType Type,

bool BringToFront = false)

C++

HRESULT CreateMessage(

MsgTargetPosition TargetPosition,

BSTR msgData,

MsgType Type,

VARIANT_BOOL BringToFront,

ITerraExplorerMessage80 ** pITerraExplorerMessage80)

Parameters

TargetPosition

An enum that determines where the message appears.

The MsgTargetPosition enum can have one of the following values:

· MTP_LEFT = 0
The message docks in TerraExplorer’s left container.

· MTP_MAIN = 2
The message appears in TerraExplorer's main container.

· MTP_MESSAGE_BAR = 3
The message appears in TerraExplorer's message bar.

· MTP_FLOAT = 4
The message appears in the default external web browser. This value is invalid for Text messages.

msgData

The message that is displayed. The MsgType parameter determines how this parameter is interpreted. If the MsgType parameter is set to TYPE_TEXT, this parameter is the text to be displayed. If MsgType parameter is set to TYPE_URL, this should be a full URL address (or a full path name) of a web page. If MsgType parameter is set to TYPE_ SCRIPT, this should be the content of the VBScript code.

Type

An enum that determines the type of message to be displayed. The MsgType can have one of the following values:

· TYPE_TEXT = 0

· TYPE_URL = 1

· TYPE_SCRIPT = 3

BringToFront

If the client for this message (i.e. the left container) already contains other items (i.e. Project Tree or HTML pages) those items appear in separate tabs. When this message is triggered, a message tab is added to that container (if the message tab already exists the message content replaces the content of the previous message). This parameter determines whether this tab becomes the active tab when the message is triggered. The parameter is ignored if TargetPosition is not set to MTP_LEFT or MTP_MAIN.

Return Value

pITerraExplorerMessage80

An ITerraExplorerMessage80 that represents the newly created message.

Exceptions

See: HRESULT Return Values for a list of possible values returned by the HRESULT.

Remarks

Several objects can own the message object that is created by this method. A rectangle for example, may own a message object that is also owned (at the same time) by a circle object. This means that both objects, the rectangle and the circle, display the same message when either object in the 3D Window or either object’s Project Tree entry is clicked.
