4<ol>
5  <li>Create directory <b>/sdcard/Download/volumes/</b></li>
6  <li>Create subdirectories for each dataset</li>
7  <li>Create a ".prop" for each data set</li>
8</ol>

10".prop" files are simple jave properties files which consist 
11of key=value pairs

13<dl>
14  <dt>name</dt>
15  <dd>The name to be desplayed on the screen</dd>
16  <dt>dir</dt>
17  <dd>The subdirectory containing the data</dd>
18  <dt>format</dt>
19  <dd>the format the data is in (raw or dicom)</dd>
20  <dt>format</dt>
21  <dd>The format of the pixes (only short & ushort supported)</dd>
22  <dt>dim</dt>
23  <dd>the X by Y by Z dimensions of the data seperated by x</dd>
24  <dt>voxeldim</dt>
25  <dd>The size of each voxel separated by a comma "," uniform = (1.0,1.0,1.0)</dd>
26  <dt>sequence</dt>
27  <dd>if it says 1file the raw data is all on one file</dd>
28  <dt>looks</dt>
29  <dd>The name of the supplied looks</dd>
30  <dt>XXXXX.opacity</dt>
31  <dd>the opacity table asociate with the XXXXX look</dd>

36<h3>Opacity table</h3>
37opacity tabls consisit of nested arrays of shorts.
38The first being intensity the second being opacity on a 0-255 scale.
39The values for each pixel in the volume are interpolated

41<h3>Color table</h3>
42The color table 
43The values are linearly interpolated from one value to the next

45<dl>
46  <dt>intensity</dt>
47  <dd>The intensity that has this "color"</dd>
48  <dt>RGB</dt>
49  <dd>Hex number describing the color this number has</dd>
50  <dt>diffuse</dt>
51  <dd>how much difuse lighting to apply to this materal 0-100</dd>
52  <dt>ambient</dt>
53  <dd>how much ambient lighting does this materal reflect 0-100</dd>
