Hi,<br>
I am new on vtk, my question is :<br>
<br>
are the mappers and filters same thing in VTK?<br>
<br>
Looking forward your reply soon.<br>

Hi Cory,<br>
<br>
Thank you for your reply.<br>
<br>
However, you said I have to compute distance from each point to my plane, then use vtkContourFilter.<br>
But I think it would be really heavy computation to compute distance from each point to the plane every time I move the plane, isn't it ?<br>
<br>
I would like to be able to display the intersection while the plane is moving. If I have a polydata like a bone or a skull or something like that, it would be really long to compute this distance, isn't it ?<br>
<br>
Thank you.<br>
-Laurent<br>

Hi,<br>

try the following code snippet. Basically, create a callback class wherein<br>

Add the callback to listen for the image plane widget's InteractionEvent.<br>

{<br>
/** do something with ipwidget and rcwidget when the ipwidget fires a<br>
an interaction event signal */<br>
}<br>
<br>
myCallback():ipwidget( 0 ), rcwidget( 0 ){}<br>
~myCallback(){ this->ipwidget= 0; this->rcwidget = 0; }<br>
vtkImagePlaneWidget* ipwidget;<br>
vtkResliceCursorWidget* rcwidget;<br>

Laurent,<br>
<br>
If your plane doesn't change orientation, then you should be able to<br>
change your isolevel value as you move the plane along its normal,<br>
thereby avoiding the distance computation, e.g., compute the distance<br>
one time relative to the current plane, then add 5 to the isolevel if<br>
your plane moves 5 units along the plane normal, etc.<br>
<br>
For a non-geometry based approach, you might use custom shaders to<br>
compute the distance of each vertex to your plane and discard<br>
fragments that aren't within some distance to the plane. This would be<br>
fast but may suffer from giving you a more-than-one-pixel-thick<br>
representation of the intersection in parts of the scene closest to<br>
the camera and perhaps missing some pixels in parts of the scene<br>
furthest from the camera.<br>
<br>
Hope that helps,<br>
Cory<br>

Hi Cory.<br>
<br>
Indeed the plane I will use can change position and direction.<br>
<br>
Please, could you explain what is custom shaders and how to use them to compute distance ?<br>
<br>
Thank you.<br>

If I do a checkout of VTK 6.0.0.rc3:<br>
<br>
$ git checkout v6.0.0.rc3<br>
<br>
<br>
And then look for files with ?border? in the name:<br>
<br>
$ find . | grep -i border<br>
./Interaction/Widgets/Testing/Cxx/TestBorderWidget.cxx<br>
./Interaction/Widgets/Testing/Cxx/vtkBorderWidgetTest1.cxx<br>
./Interaction/Widgets/vtkBorderRepresentation.cxx<br>
./Interaction/Widgets/vtkBorderRepresentation.h<br>
./Interaction/Widgets/vtkBorderWidget.cxx<br>
./Interaction/Widgets/vtkBorderWidget.h<br>
./Rendering/OpenGL/Testing/Cxx/TestImageResliceMapperBorder.cxx<br>
./Rendering/OpenGL/Testing/Cxx/TestImageSliceMapperBorder.cxx<br>
<br>
<br>
They do indeed appear to be in VTK 6.0.0 rc3. I wonder why you don?t think they?re there...?<br>

<br>
Part of this stems from the CMakeLists.txt in the example - if you use<br>
find_package(VTK) without specifying components then use ${VTK_LIBRARIES}<br>
you will basically link to everything VTK built. This is not normally what<br>
people want, and you can see the pre-6.0 version called out vtkHybrid. The<br>
wiki page below provides more background,<br>
<br>
<a href="http://www.vtk.org/Wiki/VTK/Build_System_Migration" target="_blank">http://www.vtk.org/Wiki/VTK/Build_System_Migration</a><br>
<br>
It leads to the question of why the VTK you built thinks<br>
vtkFiltersParallelFlowPaths was enabled when it was now. We will build some<br>
of the parallel modules that do not require MPI for example - they are<br>
probably in the StandAlone group, although it is possible they would be<br>
better in a parallel group of their own. The examples attempt to work with<br>
VTK 5 and 6, adding the components would make that harder to achieve which<br>
is why I think their CMake code is written the way it is.<br>
<br>
Hope that makes it clearer, thanks for bringing this up. I would like to<br>
get to the bottom of why VTK has incorrectly labelled a module as enabled<br>
that was not built.<br>

Good, it?s supposed to.<br>
<br>
<br>
<br>

<br>
<br>
It?s right, because Visual Studio is a 32-bit host, and it CANNOT LOAD 64-bit controls. It can only load ?Any CPU? controls that can be just-in-time compiled to a 32-bit architecture. The ActiViz dlls cannot be just-in-time compiled to any old architecture -- it has to match the underlying native dlls that get loaded.<br>
<br>
<br>
So, this is normal and expected behavior in the case of ActiViz. It?s strange when you first encounter it, because there aren?t many .NET controls that have this type of native code dependency. But it is the way it is, and Visual Studio itself will probably never be a 64-bit app.<br>
<br>
<br>
<br>
> Also i don't think that for it to work i need to install also 86 bit version<br>
> of activiz<br>
<br>
<br>
Yes, you do, if you want to add it the ?normal? way you add things at design time in Visual Studio. You have to add it as the 32-bit control, then switch your application?s target architecture and swap the references to the 64-bit versions... Then just ignore the Visual Studio design-time ?errors? that you get. If you can build and run it, then it?s all working as best it can.<br>
<br>
<br>
<br>
> i tried to add the control through kitware dll but it cannot find it...<br>
> Something is not right here i think...<br>
> Can you please tell me what i did wrong?<br>
<br>
<br>
I don?t think you?ve done anything wrong, because you say ?it works in runtime? -- if you had done something wrong, it wouldn?t.<br>
<br>
<br>
<br>
Cheers,<br>
