I think the question was regarding the Shear-Warp volume rendering
algorithm.<br>
<br>
There is Shear warp code in vtk, but currently, it's not working
correctly. I committed this code about a year ago, after Stefan
Bruckner and another chap (will locate name on request) donated it.
Unfortunately, the implementation was unstable and giving some dodgy
results (aside from not compiling either). I did a little work on this
to try to integrate it with nicely with vtk cvs head at the time, but
it was taking too much time and I had to stop work on it.<br>

several other cxx and header files are also relevent, browse cvs to
find them and look at the source<br>
<br>
has the header file details. The code is al in vtk/rendering, all you
need to do is edit the cmakelists files to include it in the
compilation, then tweak the rendering object factory to return the
mapper when you ask for it.<br>
<br>
If you make any progress, please let me know and I'll try (one day) to
get the code up and running.<br>

<pre wrap="">the shear transform can be based upon translation along one or two
axes.

<pre wrap="">hi, all users,
How to realize the shear-warp algorithm in VTK?I know there seems to be an open-source version in the site,but i can't find it.Did anyone use it?how about its performance?Is it a final version?I will appreciate very much if anyone can tell me how to find it.
Thank in advance.
