public final class DzzDJSApplet

extends DzzDApplet

implements IScene3DRenderCallBack

Provide an easy way to implements 3D Applet using only JavaScript.

Overview:

This class is provided to enable 3D Demo creation, without the need of java compiler, using only JavaScript and HTML.

HTML code sample:
You can use the following HTML code to include a 3D scene in your web page.

<APPLET MAYSCRIPT
archive = "dzzd.jar"
code = "dzzd.DzzDJSApplet.class"
width = "600"
height = "400">
<PARAM NAME="JavaScriptInit" value="start">
</APPLET>

JavaScriptInit
The "JavaScriptInit" parameter is used to tell the 3DzzD API to call the javascript function "start" once initialised.
You may change the value of this parameter to set you own JavaScript function.
Usually you will use this function to start loading a 3D scene and/or register other callback function as : render3DObjectMonitor,render3DWorldSpace.

JavaScript code sample:
<SCRIPT LANGUAGE="JavaScript">
function start(applet)
{
applet.getScene3DRender().getScene3D().loadScene3DFrom3DS(applet.getBaseURL(),"SCENE.3DS");
}
</SCRIPT>

This JavaScript code will load the 3DS file name "SCENE.3DS".

The given sample expect that all files are in the same directory including dzzd.jar.
