Generating an Efficient Animation


The specifications and the topics in MicroAVS3.0s Animator 2D Plus are as given below.
Frame in non-transmittable 256 color GIF format
Basically, the number of frames is unlimited. However, when using Animator 2D applets, this depends largely on the machine environment (especially, the memory size). As a guideline to display approximately 20 frames at a high speed (this also depends on the frame size), minimum amount of memory required should be greater than 64MB. A fixed performance independent of the number of frames can be expected from MicroAVS3.0 Animator 2D Plus. The Animation speed and the applet depends a little on the CPU power, speed at which the disk is accessed, and the graphics board functions. We recommend a CPU atleast of the order of Pentium 166Mhz.
Directly editing the HTML files of a project
The specification of the Anim2D.htm file generated when creating a project is as follows:
<HTML>
<HEAD>
Is absolutely necessary.
<! MicroAVS Animation File 2.0> This comment tag indicates that this file is also a MicroAVS 2.0 file. This is not displayed in the browser but is necessary to enable the file to be read in MicroAVS.
<TITLE>Animator 2D plus</TITLE>
</HEAD>
Can be edited.
<BODY BGCOLOR=#FFFFFF BACKGROUND=images/bg.gif> Defines whether background can be added using a setting button. Can also be edit ed.
<CENTER><FONT SIZE=+2>Animator 2D Plus</FONT><BR> Displays the title. Can be edited.
<! MicroAVS Animation Applet Begin> This is necessary to enable reading in MicroAVS.
<APPLET CODE=Anim2D.class WIDTH=340 HEIGHT=160> This is the applet tag. The width and height can be edited.
<PARAM NAME=FRAME VALUE=10> This is a parameter that sets the number of frames. This is mandatory.The number of frames can be edited.
<PARAM NAME=FRAMEWIDTH VALUE=200> This is a parameter that sets frame width. This is used to define the initial screen size. This can be edited. If this is not specified, a pre-determined value will be used.
<PARAM NAME=FRAMEHEIGHT VALUE=200> This is a parameter that sets frame height. This is used to define the initial screen size. This can be edited. If this is not specified, a pre-determined value will be used.
<PARAM NAME=IMAGESOURCE VALUE="images"> This parameter defines the directory in which the frames are contained using a relative path (from the directory in which the HTML file is contained). This can be edited. If not specified, the frames are assumed to be in the same directory as the HTML file.
<PARAM NAME=SOUNDS VALUE="wind.au||water.au"> This parameter defines the actual sound files. The sound files are described sep arated by ||. There is no limit on the number of sound files but keep in mind the performance. This can be edite d. If unspecified, no sound is used.
<PARAM NAME=SOUNDSOURCE VALUE="audio"> This parameter specifies the directory in which the audio files are contained us ing a relative path from this HTML text. This can be edited. If this is not specified, the directory is assume d to the same one in which the HTML file is contained.
<PARAM NAME=LANG VALUE=ja_JP> This parameter defines the language. Japanese (ja_JP) and English(C) are support ed. This can be edited. If this is not specified, Japanese is used.
</APPLET> A tag indicating the end of the applet.
<! MicroAVS Animation Applet End> Is required for reading in MicroAVS. Be careful in editing the text located between BEGIN and END.
<HR> Close the browser at the end. <BR></CENTER> can be edited.
</BODY>
</HTML>
This is mandatory.
The portion enclosed within <APPLET> </APPLET> are the minimum required tags. The rest can be edited. On the other hand, to include in ones own HTML file, only insert the portion between &GLAPPLET> and &GL/APPLET>. At this time, if the 3 tags beginning with <! MicroAVS... are inserted, this can also be read in by Animator 2D Plus. Basically, for details about HTML tags, refer the set of manuals related t o Web.
