Hi.
I downloaded opencv-2.4.9.exe and linked with Visual Studio 2012.
In the source, i cannot find the viz module.
I followed this tutorial, changing values to 249 for OpenCV.

Any clues?
How to build 'opencv_viz' module.
For Ubuntu
For windows
Note: it's recommended to compile VTK statically, because in this case 'opencv_viz.dll' will be ~15 Mb in size and fully self-contained (i.e. no external dependencies at all).
Build OpenCV with VTK.
Note: it is recommended to point build directory, not install directory.
Note: if you have several VTKs in your system and wrong version is found, you may force concrete version via setting VTK_DIR environment variable to proper path.
For Macos
It's possible, I made it! And I tested it for OS X 10.9 with VTK 6.2 from vtk development repository. I don't remember my steps that's why don't publish them here.
Don't forget to do: sudo make install
see: http://docs.opencv.org/doc/tutorials/introduction/linux_install/linux_install.html
Sorry, this doesn't help me on windows, with vtk and successfull cmake for it, there still no opencv_viz.dll after building ALL_BUILD.
@stiv-yakovenko post a new question if you don't use opencv 2.4.9
for opencv 3 it should be not path-to-build-directory-of-VTK, but vtk cmake file folder
The new viz module exists in OpenCV-2.4.9 sources but was not included into pre-built libraries since it depends on VTK that assumes redistribution of pre-built VTK with the package.
For those who needs the viz module we suggest building OpenCV-2.4.9 from sources with -DWITH_VTK=ON CMake option. (Use -DVTK_DIR=/your/vtk/build/path to help CMake finding VTK).

did you include the correct header file (opencv2/viz/...)? Because the standard opencv.hpp doesn't include it yet as you can see here
it's a 3.0 feature only.
euhm viz is added as 2.4.9 looking at the changelog which clearly states that "New VTK-based 3D visualization module viz stabilized and back-ported to 2.4 branch." So this is actually a bug and this should be fixed!
ehum, right.sorry.
Intellisense cannot find the include that we want. I am working from the tutorial sample with that include line.
@StevenPuttemans Is it QT related?
no it is not :) the viz interface is based on the VTK package for 3D modelling. Problem is that with the integration of viz module inside the 2.4 branch, errors were solved BUT they didn't think of fixing all headers to be properly included. Saw you opened a bug report. Link it to this topic and wait until someone starts fixing those headers or do so yourself. The files are there, the correct references in other files not! A dumb way could be to include all the source and header files of the viz module in your project, but don't think this will work .. worth a try tough.
@berak : its just a matter of checking first then replying :P I almost made the same mistake ^_^
I'll post the link. I'm building trunk from source, hopefully that'll work out. :)
Won't solve it, just looked at the 2.4 branch, it seems that headers are not included at the correct places. However I haven't got the knowledge where it should all be added :D
