Thanks, Serge. It *is* too bad that the kickstarter approach did not yield a funded project this time around. Perhaps later, another one will be successful.<br>
<br>
<br>
<br>
Alex, you wrote ?as for me I would trust more in the results of free development than in results of the projects developed using such financing.?<br>
<br>
<br>
<br>
In response, I would simply point out the results of free development are that ActiViz is presently ?stuck? on the VTK 5.8 version. And it was only ?free as in beer? to those of you who didn?t pay for it.<br>
<br>
<br>
<br>
It?s also too bad that nobody else has stepped up and said, ?hey, how can I contribute and help to make this happen?? (Aside from the 20 kickstarter project backers [1] -- thanks again, guys...)<br>
<br>
<br>
<br>
For those willing to contribute effort and manpower to the problem, rather than money, go for it. VTK and ActiViz are both open source, and may be built and extended by any interested party. I recently abandoned the topic integrating the two [2] due to lack of activity. Anybody who wants to, please feel free to resurrect it, rebase it on current ?master?, and try again. Alternatively, you could simply extend the ActiViz git repo with commits to make it build against an external VTK 5.10 or 6.0 [3].<br>
<br>
<br>
While I am capable and mildly interested in furthering ActiViz .NET, I prefer to spend much of my free time on non-computer related activities these days. I get quite enough compute time just doing my job. But money actually does motivate me... and I would be willing to do the work if paid for it. So, that, plus gauging actual interest level, were my primary motivations for seeking funding via kickstarter.<br>
<br>

P.S. ---<br>

<br>
I would also like to point out that nowadays, you can simply build a managed-C++ project with VS 2012, and ?just link for free? to the native VTK C++ libraries. That doesn?t help folks using other .NET languages, but it is a nice feature of the modern C++ compiler from MS that you can link in both managed and un-managed code together. If you are starting a new Windows Forms application, consider using managed C++ as your language.<br>

Hi,<br>
<br>
I have two triangle cells in my vtkCellLocator and I create a little bb<br>
around a point of one triangle (see picture). Now I use FindCell(bb, idList)<br>
and I should get one id, but I get two. Is this a bug, or must I change<br>
something?<br>

- two trinagles (red)<br>

<br>
My code:<br>
<br>
for (vtkIdType ptId = 0; ptId < geometry->GetNumberOfPoints(); ++ptId)<br>
{<br>
bounds[0] = trianglePoint[0] - 0.01;<br>
bounds[1] = trianglePoint[0] + 0.01;<br>
bounds[2] = trianglePoint[1] - 0.01;<br>
bounds[3] = trianglePoint[1] + 0.01;<br>
bounds[4] = trianglePoint[2] - 0.01;<br>
bounds[5] = trianglePoint[2] + 0.01;<br>
<br>
cellLocator->FindCellsWithinBounds(bounds, foundCells);<br>
<br>
int size = foundCells->GetNumberOfIds(); // is always two<br>
}<br>
<br>

Thx<br>

<br>
It is not clear that attached picture corresponds to your claims.<br>
There is no visible relation between trianglePoint and<br>
geometry->GetNumberOfPoints().<br>
Also for (vtkIdType ptId = 0; ptId < geometry->GetNumberOfPoints(); ++ptId)<br>
loop does not make any sense cause nothing changes in the loop.<br>
<br>
So I guess your trianglePoint is not what you think it is.<br>
For example if this point is shared by 2 triangles you will have the same<br>
effect.<br>
Another possible problem might be absolute value 0.1 used.<br>
For example your triangle may have size smaller than it, which will be a<br>
source of such effect too.<br>
<br>
Your example is not complete , you could create much better example<br>
initializing all available variables so the behavior can be reproduced.<br>

Dear All:<br>
<br>
I have several renders (e.g 4 render), and we could use SetViewport to<br>
display all of them in one RenderWindow.<br>
<br>
My question is that could I set different interactor for each of the render?<br>
<br>
For example, for render1, I only need zoom and ww/wl operation, but for<br>
render2, I need zoom, pan and rotate operation.<br>
<br>
<br>
<br>
Thanks a lot.<br>

Hello,<br>

I use pythonxy() as my platform for python supported vtk. Currently,<br>
I'm trying to export a vtk render window to post script using the sample<br>
code (at bottom) but I'm getting an error (see below). I suspect this<br>
relates to how pythonxy() is compiled. Can anyone suggest a workaround?<br>

Thank you!<br>
The problem is that when I tried with ImageData as input in volume16reader I<br>
got the error "Attempt to connect input port index 0 for an algorithm with 0<br>
input ports"<br>
Using ImageData as input directly to vtkImagePlaneWidget worked fine though,<br>
so I guess that solves it.<br>
(My VTK-programming right now is mostly trial and error along with trying to<br>
understand the different data structures and the pipeline)<br>

Hello everyone,<br>
<br>
I am new to vtk. I am having a wavefront file of a 3d human model. What I want to do is to render it using vtk and apply different textures to different parts of the 3d human model. For example I have a texture image containing a shirt that I want to apply to torso and arms only. Another one for jeans that I want to apply to legs and thighs only. I will really appreciate if anyone can provide a sample code snippet to get me started.<br>
<br>
<br>
thanks in advance.<br>
<br>
Regards<br>
Umer<br>

Dear vtkUsers,<br>
<br>
I am trying to find the orientation of an actor while I'm rotating it, the z<br>
and y are correct, but the value range for the x axis is [-90, 90], whereas<br>
the value range for z and y axis is [-180, 180].<br>
<br>
<br>
<br>
Also the rotation doesn't happen in the chosen axis, for example when I<br>
chose to rotate the actor by 15 degrees on y-axis, the value of the z-axis<br>
increases.<br>
<br>
<br>
<br>
<br>
<br>

Sry... I thought it would be clear what I mean.<br>
<br>
The geometry contains two triangles:<br>
Points are:<br>
(0 0 0)<br>
(0 10 0)<br>
(10 0 0)<br>
(10 10 0)<br>
<br>
with connection:<br>
(0 1 2)<br>
(1 2 3)<br>
<br>
for (vtkIdType ptId = 0; ptId < geometry->GetNumberOfPoints(); ++ptId)<br>
{<br>
geometry->getPoints()->GetPoint(ptId, trianglePoint);<br>
<br>
bounds[0] = trianglePoint[0] - 0.01;<br>
bounds[1] = trianglePoint[0] + 0.01;<br>
bounds[2] = trianglePoint[1] - 0.01;<br>
bounds[3] = trianglePoint[1] + 0.01;<br>
bounds[4] = trianglePoint[2] - 0.01;<br>
bounds[5] = trianglePoint[2] + 0.01;<br>
<br>
cellLocator->FindCellsWithinBounds(bounds, foundCells);<br>
<br>
int size = foundCells->GetNumberOfIds(); // is always two<br>
}<br>
<br>
The trianglePoint is e.g. (0 0 0) (first iteration of the loop) so I should<br>
get only one triangle, but I get always two triangles. The bb is small<br>
enough and there is a point which correspons to only one triangle.<br>
<br>

Hi,<br>
<br>
I'm implementing a VTK application for visualizing geometrical 3D objects.<br>
Most of the code is written in C++, and I use TCL-TK widgets for the GUI (I<br>
use *vtkTkRenderWidget* for the main canvas).<br>
<br>
Most of my objects are *vtkVoxel* objects inserted into a *<br>
vtkUnstructuredGrid*.<br>
<br>
I run this application on a Linux server and I connect to this server from<br>
Windows using VNC. I noticed that when I load a very large data set into<br>
the application then the *VNC server* (on the Linux machine) consumes a lot<br>
of memory and uses 100% CPU. I didn't realize that the memory and CPU<br>
usages of a VNC server would be affected so much like this.<br>
<br>
Note that my VTK application is also consuming a lot of memory and CPU,<br>
but what I find strange is that the VNC server is also affected (the<br>
process is called *Xvnc_core*).<br>
<br>
Does anyone know how this is caused and do you have any suggestion how to<br>
mitigate the problem?<br>
<br>
Regards,<br>
Haroon<br>

If your data is 512x512x512 then<br>
reader->SetDataExtent(0,512,0,512,0,512);<br>
should be:<br>
reader->SetDataExtent(0,511,0,511,0,511);<br>
<br>
Also be certain you are setting the correct endianness.<br>

All i get is an empty renderWindow. I get no errors, but no data is rendered<br>
either. What am I doing wrong?<br>
<br>
What I do is pretty much this:<br>
<br>
AtomGrid=vtk.vtkUnstructuredGrid()<br>
AtomGrid.SetPoints( vtkPoints with [index,x,y,z] )<br>
AtomGrid.GetPointData().SetScalars( vtkFloatArray with [index, scalar]<br>
)<br>
<br>
volMapper = vtk.vtkUnstructuredGridVolumeRayCastMapper()<br>
volMapper.SetBlendModeToComposite()<br>
volMapper.SetInput(AtomGrid)<br>
<br>
<br>
I tried volMapper.SetScalarModeToUsePointFieldData(), but then it claims<br>
that I have no scalar values to use(!!)<br>
<br>
(I cheated before, and was satisfied using ImageData for this, but now I<br>
really need to get this to work with UnstructuredGrid)<br>
