All Implemented Interfaces:

BrowserFactoryImpl

public class VRMLOGLBrowserFactoryImpl
extends Object
implements BrowserFactoryImpl

An implementation of the EAI BrowserFactoryImpl interface that creates a browser that uses OpenGL for the renderer.

Supported Actions

Currently the factory implementation only supports creating a new component. We do expect to add other support at a later date, such as fetching an existing instance.

Component Creation

This implementation allows you to create a new component that is ready to place content in. Parameters can be supplied and are declared in the form

   param name=param value
 

There should be no whitespace either side of the equals sign.

When creating a new browser component, the following parameters are supported:

Parameter Name String	Parameter Value String - Description
Xj3D_InterfaceType	awt|swing|swing-lightweight|newt. Indication as to whether the UI should be AWT or SWING based. The SWING option may also use a purely lightweight renderer that does not suffer from the usual heavyweight rendering problems with menus etc. However, if you are not using the OpenGL 2D pipeline in Java 8+, then you're likely to have significant performance loss. If not supplied the default is to use the native windowing toolkit (NEWT) renderer.
Xj3D_NavbarShown	true|false. Show or hide the navigation bar on the screen. If not provided, the navigation bar will be shown.
Xj3D_NavbarPosition	top|bottom. If the navigation bar is shown, it should be placed at the desired location in the panel. If not provided, the navigation bar will be on the bottom.
Xj3D_LocationShown	true|false. Show or hide the panel that describes the current URL and allows the user to enter new URLs. If not provided, the location bar will be shown.
Xj3D_LocationPosition	top|bottom. If the URL bar is shown, it should be placed at the desired location in the panel. If not provided, the position will be at the top of the panel.
Xj3D_LocationReadOnly	true|false. If the URL bar is shown, you can make it read-only (ie not allow the user to change the URL). If not provided, the bar will be writable.
Xj3D_ShowConsole	true|false. Indication as to whether the component should automatically show the console on startup. Default is to hide.
Xj3D_ShowConsole	true|false. Indication as to whether the component should automatically show the console on startup. Default is to hide.
Xj3D_OpenButtonShown	true|false. Indication as to whether the component should have an Open button to load content. Default is false.
Xj3D_ReloadButtonShown	true|false. Indication as to whether the component should have a Reload button to reload content. Default is false.
Xj3D_StatusBarShown	true|false. Indication as to whether the component should have StatusBar. Default is false.
Xj3D_FPSShown	true|false. Indication as to whether the StatusBar should have a frames-per-second display. Default is false.
Xj3D_ContentDirectory	Initial directory to use for locating content. Default is obtained from the System property "user.dir".
Xj3D_AntialiasingQuality	"low"|"medium"|"high". Default is "low".
Xj3D_Culling_Mode	String	"none"|"frustum". OGL Culling mode. Default is "frustum".
Antialiased	true|false. Indication as to whether the antialiasing should be enabled. Default is false.
Shading	true|false. Indication as to whether the shading should be enabled. Default is false.
PrimitiveQuality	"low"|"medium"|"high". Primitive geometry quality. Default is "medium".
TextureQuality	"low"|"medium"|"high". Texture quality. Default is "medium".

VRMLOGLBrowserFactoryImpl

public VRMLOGLBrowserFactoryImpl()

Create a new instance of this factory.

Method Details

createComponent

public VrmlComponent createComponent(String[] paramList)
                              throws NotSupportedException

Description copied from interface: BrowserFactoryImpl

Create a VRML browser that can be used as an AWT component. The component returned is guaranteed to be an instance of VrmlComponent.

Specified by:

createComponent in interface BrowserFactoryImpl

Parameters:

paramList - Parameters to control the look and feel.

Returns:

The component browser initialised to be empty.

Throws:

NotSupportedException - The implementation does not support this type of VRML browser.

getBrowser

public Browser getBrowser(Applet applet)
                   throws NotSupportedException,
NoSuchBrowserException,
ConnectionException

Description copied from interface: BrowserFactoryImpl

Get a browser from the given java applet reference as a base in the current HTML page. Used when attempting to access a browser on the current page as this applet and is the first browser on the page. Generically, the same as calling getBrowser(applet, "", 0);

Specified by:

getBrowser in interface BrowserFactoryImpl

Parameters:

applet - The applet reference to use

Returns:

A reference to the Browser implementation

Throws:

NotSupportedException - The implementation does not support this type of VRML browser

NoSuchBrowserException - Could not locate a VRML browser on the same page as the applet.

ConnectionException - An error occurred during the connecting process

getBrowser

public Browser getBrowser(Applet applet,
 String frameName,
 int index)
                   throws NotSupportedException,
NoSuchBrowserException,
ConnectionException

Description copied from interface: BrowserFactoryImpl

Get a browser from the given java applet reference one some named page and at some embed location. Used when attempting to access a browser on another HTML page within a multi-framed environment, or if there are a number of VRML browser instances located on the same page.

If the frame name is a zero length string or null then it is assumed to be located on the same HTML page as the applet. The index is the number of the embed VRML browser starting from the top of the page. If there are other non-VRML plugins embedded in the page these are not taken into account in calculating the embed index.

Specified by:

getBrowser in interface BrowserFactoryImpl

Parameters:

applet - The applet reference to use

frameName - The name of the frame to look into for the browser

index - The embed index of the VRML browser in the page

Returns:

A reference to the Browser implementation

Throws:

NotSupportedException - The implementation does not support this type of VRML browser.

NoSuchBrowserException - Could not locate a VRML browser on the same page as the applet.

ConnectionException - An error occurred during the connecting process

getBrowser

public Browser getBrowser(InetAddress address,
 int port)
                   throws NotSupportedException,
NoSuchBrowserException,
UnknownHostException,
ConnectionException

Description copied from interface: BrowserFactoryImpl

Get a reference to a browser that is located on a remote machine. This a server application to send scene updates to a number of client browsers located on remote machines. If there are a number of browsers running on a remote machine, they can be differentiated by the port number they are listening on.

There is no default port number for VRML browsers.

Specified by:

getBrowser in interface BrowserFactoryImpl

Parameters:

address - The address of the machine to connect to

port - The port number on that machine to connect to.

Returns:

A reference to the Browser implementation

Throws:

NotSupportedException - The implementation does not support this type of VRML browser.

NoSuchBrowserException - Could not locate a VRML browser on the same page as the applet.

UnknownHostException - Could not find the machine named in the address.

ConnectionException - An error occurred during the connecting process
