<div>Hi, all:</div>
<div> </div>
<div>I have a problem with reading the txt file whose size is around 200M in order to visualize it, the error message I get is as follows:</div>
<div> </div>
<div><font size="1">
<p><font color="#ff0000" size="4">First-chance exception at 0x7d4e237e in 2.exe: Microsoft C++ exception: std::bad_alloc at memory location 0x016dfc54..</font></p>
<p><font color="#ff0000" size="4">Unhandled exception at 0x7d4e237e in 2.exe: Microsoft C++ exception: std::bad_alloc at memory location 0x016dfc54..</font></p></font></div>
<div> </div>
<div>I do can read a 30M txt file successfully, actually the physical memory is not a problem I think (since I run the program on a 64-bit winXP with 4G memory and 8CPUs), as you see above I still get the problem wtih memory allocation, I also checked the physical memory usage right before the error message poped up, it consumed only around 2G physical memory, could anyone help me figure this out? </div>
<div>Thanks a lot!</div>
<div> </div>

Content-Type: text/plain; charset=us-ascii; format=flowed; delsp=yes<br><br>Hello,<br><br>my name is Christopher and I'm a CS student currently searching for a<br>topic for my bachelor's thesis. One topic that I'd find particularly<br>
interesting is an application that visualizes rendered volumes and<br>allows the user(s) to explore the set of data by using multitouch<br>gestures.<br>For an example of how this may look in practice, please see this<br>remarkable video: <a href="http://www.vimeo.com/6866296" target="_blank">http://www.vimeo.com/6866296</a><br>
<br>For the rendering part, I would like to use VTK so I don't need to<br>write the volume rendering myself.<br>The actual GUI and interaction would be made with PyMT [0], a python<br>library that allows you to write multitouch applications with ease.<br>
<br>There are two main problems here that I already see:<br> a) Is it possible to take the rendered volume and use it in my PyMT<br>application (which has an OpenGL context itself)? Of course, this<br>needs to be fast enough to allow for actual interaction with the user.<br>
If yes, how would I do that?<br> b) What do I need to do in order to translate finger gestures into<br>VTK commands like 'rotate the volume' or 'show everything up to that<br>particular slice'? Is that even possible properly?<br>
<br>I understand that (as chapter 13 of the user's guide explains) you can<br>subclass vtkRenderWindowInteractor and friends, but those seem a bit<br>mouse and keyboard centric (because you need to override methods such<br>
as onMiddleButtonDown()). However, both mouse and keyboard is<br>something you do not usually have in a multitouch environment (as you<br>can clearly see in the above video).<br><br>I would be really happy if it would be possible to realize the<br>
application sketched above. Thoughts on achievability are also very<br>happily accepted. Keep in mind that this will be a bachelor's thesis<br>with 3-6 months (of non-exclusive working time spent) and not a<br>doctoral thesis.<br>

Content-Type: text/plain; charset=ISO-8859-1<br><br>Hi Christopher,<br><br>VTK should be able to draw into the OpenGL context that is provided by<br>your python library. You just have to call vtkRenderWindow::WindowInfo()<br>
and vtkRenderWindow::SetSize() so that VTK will use your context instead<br>of creating its own.<br><br>For example, I do the following to get VTK to draw into a PyQt window:<br><br> def polish(self):<br> self._RenderWindow.SetSize(size.width(),size.height())<br>
self._RenderWindow.SetWindowInfo(str(int(self.winId()))<br><br>This works because Qt calls the "polish()" method on my qtRenderWidget<br>before the Qt window is mapped to the screen. When that happens,<br>
I get the size and window ID from the Qt window, and use those to<br>set up the RenderWindow.<br><br>So if PyMT can give you the window Id of the window that it uses for<br>OpenGL, then getting VTK to use that window should be easy.<br>
<br>With respect to the interactors, it might be easiest not to use them at<br>all. You can write your own code that takes the multi-touch information<br>from PyMT, and then use the vtkPicker yourself and directly modify<br>
the Prop3D and clipping plane as necessary. By all means take a look<br>at the vtkInteractors, just realize that you don't necessarily have to use<br>them.<br><br> David<br><br><br>On Fri, Oct 16, 2009 at 10:06 AM, Christopher Denter<br>

one render window<br>To: "'VTK users group'" <<a href="mailto:vtkusers@vtk.org">vtkusers@vtk.org</a>><br>Message-ID: <003f01ca4ea3$796c7ff0$6c457fd0$@com><br>Content-Type: text/plain; charset="us-ascii"<br>
<br>Hi All,<br><br>I have a question on the interaction on the rendered window. Here is a<br>snippet of my code:<br><br> vtkRenderer* renderer1 = vtkRenderer::New();<br> vtkRenderer* renderer2 = vtkRenderer::New();<br><br>
vtkRenderWindow* renWin = vtkRenderWindow::New();<br><br> renWin->AddRenderer(renderer1);<br> renWin->AddRenderer(renderer2);<br><br> renderer1->SetViewport(0.0, 0.0, 0.5, 1.0);<br> renderer2->SetViewport(0.5, 0.0, 1.0, 1.0);<br>
<br> vtkRenderWindowInteractor* inter = vtkRenderWindowInteractor::New();<br> inter->SetRenderWindow(renWin);<br><br> ... (Add mapping data to renderer1 and renderer2)<br><br> // add axes<br> vtkAxesActor* axes = vtkAxesActor::New();<br>
vtkPropAssembly* assembly = vtkPropAssembly::New();<br> assembly->AddPart(axes);<br><br> vtkOrientationMarkerWidget* widget1 = vtkOrientationMarkerWidget::New();<br> widget1->SetOrientationMarker( assembly );<br> widget1->SetInteractor(inter);<br>
widget1->SetViewport( 0.0, 0.0, 0.2, 0.2 );<br> widget1->SetEnabled(1);<br> widget1->InteractiveOff();<br><br> renWin->Render();<br> inter->Start();<br><br>With this code, the object interactions in renderer1 and renderer2 are not<br>
correlated. Here, I would like the interactor (inter) acts simultaneously<br>for objects in renderer1 and renderer2. For example, when I rotate or zoom<br>in/out the object in renderer1, the object in renderer2 should change the<br>
same way as object in renderer1 does. Further, with this code, the axis<br>orientation will change along the object orientation in renderer1, but not<br>the one in renderer2. However, if I switch the Viewports of renderer1 and<br>
renderer2, the axis orientation will change along the object orientation in<br>renderer2, but not the one in renderer1. Can anyone give me some hints to<br>resolve this problem?<br><br>Thank you!<br>-Jinzhong<br><br><br><br>

Content-Type: text/plain; charset="us-ascii"<br><br>Hello: I posted a similar question some time ago and got no response. Since then I have found a workaround to solve my problem.<br><br>But on Oct 13, 2009, Microsoft pushed a Windows update for KB958869. All the sudden my workaround failed to work. The MS update changed the Windows GdiPlus.dll file to prevent centain buffer overrun issues.<br>
<br>Can anyone please help?<br><br>Here is the code that gives the problem. It is 2D image rotating with vtkImageReslice and vtkTransform.<br><br>If you try the code, it works just fine! The problem is, we are using the code in the same application that uses a 3rd party library utilizing DirectX hardware acceleration.
