The animation targets are the material's colors, the SRT of the UV coordinates, and the texture patterns. 15</p> 16 17<h2>Defining Animation on the <CODE>CMDL</CODE> Side</h2> 18<p> 19The animation data are defined in a <CODE>.mata</CODE> file, but you also must set definitions for animation on the <CODE>.cmdl </CODE>side for the model data to which the animation data will be applied. The intermediate format can handle skeletal animation as well as a number of other kinds of animation including material animation and visibility animation. Each kind of animation is called an <I>animation group</I>. The <CODE><GraphicsAnimationGroupDescription></CODE> element is defined in order to clearly indicate which animation group(s) to apply to a model. Contained in this element is information about the animation group type(s), the timing with which the animation(s) will be applied, and the reference to the element(s) inside the <CODE>.cmdl</CODE> file that will be overwritten by the animation(s). 20</p> 21 22<h3>XML Hierarchical Structure</h3> 23<p> 24The <CODE><AnimationGroupDescriptions></CODE> element appears only once inside the <CODE><SkeletalModel></CODE> element and indicates the start of the definitions of the <CODE><GraphicsAnimationGroupDescription></CODE> element(s). If there are multiple types of animation groups, then multiple <CODE><GraphicsAnimationGroupDescription></CODE> elements are defined. 25</p> 26<table> 27<tr><td> 28<pre> 29<NintendoWareIntermediateFile><br> 30 <GraphicsContentCtr><br> 31 <Models><br> 32 <SkeletalModel><br> 33 <AnimationGroupDescriptions><br> 34 <GraphicsAnimationGroupDescription><br> 35</pre> 36</td></tr> 37</table> 38 39<h2>Actual Definitions on the <CODE>CMDL</CODE> Side</h2> 40<p> 41The CMDL side is defined as shown below for material animation.
