Hi Sebastien,<br>
<br>
Nice work. I am very much interested to get some feedback about
your experience.<br>
<br>
Are you splitting the 3D data into multiple files?<br>
</blockquote>
In our case, the data is just 3 .vtk files parsed by the JavaScript
client. One file for the skin, one for the bones and one for the
lung.<br>
<br>
<blockquote cite="mid:4F0BF172.1090607@aol.com" type="cite"> What is
the size of 3D data file?<br>
</blockquote>
quite small in that case : about 200kB<br>
<br>
<blockquote cite="mid:4F0BF172.1090607@aol.com" type="cite"> Is the
3D constructed at runtime?<br>
</blockquote>
<br>
the 3D scene is constructed by the client, there is no work on the
server-side, apart from serving the files. This is the simplest case
of use for us.<br>
<br>
I did not know ParaviewWeb had webGL abilities, but at the moment,
it seems rather complex to install and to use. Maybe future releases
will improve that?<br>
<br>

Hi Sathish,<br>
<br>
interesting webpage! It's good to finally see webGL stuff
reaching the VTK ecosystem! We also have developed something in
our lab, see:<br>

<br>
it is a primitive simultaneous visualization of IRM slices and
extracted parts of bones and lung. We've been doing this
ourselves as there was no practical library to do that at that
time.<br>

One of the features planned for Oviyam-5 is to view 3D images
from a DICOM series and without a plugin using WebGL. We've
just taken the first steps towards reaching that goal.<br>
<br>
A technology preview with pre-rendered images is available at
this <a moz-do-not-send="true" class="jive-link-external"
href="http://www.raster.in/demos/vtkwebgl/index.html">link</a>.
Be patient while loading the 3D models, it may take few
minutes to load.<br>
<br>
Technologies used: VTK, HTML5, WebGL, JSON, Javascript,
JS-Unzip...<br>
<br>
<b>Features:</b><br>
1. Plugin-Free Design.<br>
2. Supports all major modern browsers like Chrome, Firefox,
Safari and Opera.(Use the latest versions available.The best
performance is with Chrome and Firefox.<br>
3. Supports IPhone, IPad and Android devices. However, due to
the lack of memory, only the cube demo works at present<br>
4. Load upto 36 MB of JSON 3D Data (Supports nearly 150
instances/slices).<br>
5. Zoom In/Out Option.<br>
6. Pan Option.<br>
7. One click Axial, Coronal, Sagittal Views.<br>
8. 2D Rotation.<br>
9. 3D Rotation.<br>
<br>
<b>Upcoming features:</b><br>
1. Data Compression(Zip/Unzip) support for faster data
transfer.<br>
2. Support for Handheld devices.<br>
3. Look-Up Table to get colour.<br>
4. Support for user-defined models.<br>
