<h1>A Volume Renderer</h1>
<h2>To setup to load DICOM or RAW data</h2>
<p> 
<ol>
  <li>Create directory <b>/sdcard/Download/volumes/</b></li>
  <li>Create subdirectories for each dataset</li>
  <li>Create a ".prop" for each data set</li>
</ol>

".prop" files are simple jave properties files which consist 
of key=value pairs 

<dl>
  <dt>name</dt>
  <dd>The name to be desplayed on the screen</dd>
  <dt>dir</dt>
  <dd>The subdirectory containing the data</dd>
  <dt>format</dt>
  <dd>the format the data is in (raw or dicom)</dd>
  <dt>format</dt>
  <dd>The format of the pixes (only short & ushort supported)</dd>
  <dt>dim</dt>
  <dd>the X by Y by Z dimensions of the data seperated by x</dd>
  <dt>voxeldim</dt>
  <dd>The size of each voxel separated by a comma "," uniform = (1.0,1.0,1.0)</dd>
  <dt>sequence</dt>
  <dd>if it says 1file the raw data is all on one file</dd>
  <dt>looks</dt>
  <dd>The name of the supplied looks</dd>
  <dt>XXXXX.opacity</dt>
  <dd>the opacity table asociate with the XXXXX look</dd>
  <dt>XXXXX.color</dt>
  <dd>The color table asociated with the XXXXX look</dd>
</dl>

<h3>Opacity table</h3>
opacity tabls consisit of nested arrays of shorts.
The first being intensity the second being opacity on a 0-255 scale.
The values for each pixel in the volume are interpolated 
<p></p>
<h3>Color table</h3>
The color table 
The values are linearly interpolated from one value to the next 

<dl>
  <dt>intensity</dt>
  <dd>The intensity that has this "color"</dd>
  <dt>RGB</dt>
  <dd>Hex number describing the color this number has</dd>
  <dt>diffuse</dt>
  <dd>how much difuse lighting to apply to this materal 0-100</dd>
  <dt>ambient</dt>
  <dd>how much ambient lighting does this materal reflect 0-100</dd>
  <dt>specular</dt>
  <dd>How much specular reflection materal has 0-100</dd>
</dl>
