How are interactive animations created? |
||||||||||||||||
|
All interactive animations on the gallery page were created in the Visviva Authoring Studio, which automatically generate codes in ScriptV class and object files. To make them understandable, some files available in source were edited and helpful comments have been added. It is also possible to create these animations using a plain text editor, if you are a programmer and familiar with the ScriptV language, a powerful and standalone object-oriented programming language (similar to Java). To do this, you will first need to download the free Visviva Animation Engine and its reference manual as well as the ScriptV User's Manual.

How fast will these animations run on my computer? |
||||||||||||||||
|
The speed at which the animations play will vary depending on the type of video card you have installed in your computer. We have tested all animations on various brands of video cards. As long as your computer supports OpenGL acceleration, the 3D animations should run in real-time. The Direct3D version (based on DirectX 8.x) will be availabe in the 4Q 2001. When this version is available, older computers that have D3D card only should be able to run the 3D animation in a satisfied performance. |

How can I view VAE animations in a web browser? |
||||||||||||||||
|
The animations in this gallery may only be viewed with the VAE Web Plug-In. This 1.6 megabyte file allows interactive animations and applications to be viewed automatically from Internet Explorer and Netscape Communicator browsers. Clicking on any picture in the gallery will begin downloading the VAE Web Plug In. This plug-in only needs to be downloaded once. For best results, use Internet Explorer 4.0 or higher, or Netscape Communicator 4.75. |

|
How can I upgrade the VAE Web Plug-in? |
||||||||||||||||
|
If you are using an Internet Explorer browser, the upgrade is automatic. When a new version of the plug-in is detected, the Internet Explorer will start downloading the new version automatically. If you are using Netscape Communicator 4.75, you will have to check the Edit > Preferences menu to open the Preference dialogue, choose the Smart Upgrade command, and uninstall the VAE plugin. Or you can simply use our Netscape VAE Plug-In Dowload page, and download the plug-in manually.

Where is the cache for my downloaded animation files? |
||||||||||||||||
|
If you have installed the Visviva Animation Engine, the cache for the downloaded animation files is located in the directory in which the VAE was originally installed. You should find the subdirectory VAEDownload in this directory. All downloaded files are added to the subdirectory in the same hierarchy as they are originally inserted. Therefore, you can play the downloaded animation stand alone directly from the cache. If you did not install the Visviva Animation Engine, the cache for the downloaded animation files is located in your web browser's temporary internet files. For instance, if you are running Internet Explorer 5.0, the VAE downloaded cache can be found in the Content.IE5 directory, where you should see the subdirectory VAEDownload. VAE checks the file versions and will automatically update the files in the cache. You do not need to delete the cache files in order to update. |

How do I publish VAE Animation on the Web? |
||||||||||||||||
|
If you have the Visviva Authoring Studio, the job is easy. The tool will generate the HTML code for you. If you would like to create the HTML code by your own, you need to insert an object control in your HTML web page, using the OBJECT or the EMBED tag. What follows is a template for the Microsoft Internet
Explorer: <OBJECT ID=vaectrl WIDTH=256 HEIGHT=256 CLASSID="CLSID:CFC01863-0CCE-43F6-8790-7A5DC52ABEC0" CODEBASE="http://www.visviva.com/webplug/VaeCtrl.CAB#version=1,0,0,5"> <PARAM NAME="BackGround" VALUE="0"> <PARAM NAME="AnimRef" VALUE="http://www.visviva.com/gallery/Firework/firework.vobj"> </OBJECT> For Netscape Communicator, use the following template: <EMBED NAME="vaectrl" PLUGINSPAGE="http://www.visviva.com/download/webplug/npvaeplug.html" src="http://www.visviva.com/gallery/Firework/firework.vobj" width=256 height=256 TYPE="application/x-Netscape-VAE-Plugin-VAE" > |
||||||||||||||||
|
Here is an example using a button and JavaScript to
call the ResizeFullScreen function:
<form>
<INPUT TYPE=BUTTON NAME="FullScreen"
VALUE="Full Screen"
ID=FullButton onClick="showfullscreen()"
LANGUAGE="JavaScript"
>
</form>
<SCRIPT LANGUAGE="JavaScript">
function showfullscreen()
{
document.vaectrl.ResizeFullScreen()
}
</SCRIPT>
Once the VAE animation page is entered, we encourage you to use the ScriptV language, which contains more than 500 preset classes with hundreds of functions. Because the Internet Explorer and Netscape Communicator browsers use different methods, you will have to use a script to distinguish this situation for both cases. What follows is a template that you can use to publish your VAE animations on the web for both Internet Explorer and Netscape Communicator:
<SCRIPT LANGUAGE="JavaScript">
TempString = navigator.appVersion
if (navigator.appName == "Microsoft Internet Explorer")
{
document.writeln('<OBJECT ID=vaectrl WIDTH=256 HEIGHT=256 CLASSID="CLSID:CFC01863-0CCE-43F6-8790-7A5DC52ABEC0" CODEBASE
