[vtkusers] another vtk error

Thu Jan 30 15:40:02 EST 2014

More details:

The very first error I get is when I initialize my interactor:

Here is the code:

////////////////////////////////////////////////////////////////////////////////////

  if ( self = [super initWithFrame:frame])

{

_renderer = vtkOpenGLRenderer::New();

_cocoaRenderWindow = vtkCocoaRenderWindow::New();

_cocoaRenderWindow->SetWindowId( self);

_cocoaRenderWindow->AddRenderer(_renderer);

_interactor = vtkCocoaRenderWindowInteractor::New();

        _interactor->SetRenderWindow(_cocoaRenderWindow);

[self setVTKRenderWindow:_cocoaRenderWindow];

      _interactor->Initialize();

    }

////////////////////////////////////////////////////////////////////////////////////////////////////////////////

and here is the error:

2014-01-30 15:37:15.430 OsiriX[65632:303] invalid pixel format

2014-01-30 15:37:15.430 OsiriX[65632:303] invalid context

ERROR: In /Users/aaron/src/VTK/Rendering/OpenGL/vtkOpenGLRenderer.cxx, line 1202

vtkOpenGLRenderer (0x10e09ab00): failed after Clear 1 OpenGL errors detected

  0 : (1286) Invalid framebuffer operation

In the old code, I would get an "invalid pixel format" error, but it would still render.

Cheers,
Aaron

Perhaps this is similar to the following thread:

Thanks, Aashish.  I am running OSX 10.8 Mountain Lion with the master version of VTK.
OSX is running in a VM.  I have a version of my software linked to 5.8 that runs fine on the VM.

Can you provide more information about the system? What OS? Version of VTK (assuming 6.1), Graphics Card etc? (May be you did already in some other email?)

Also, it would be helpful if you can post some same code and data.

Thanks,
Aashish

Let me add that this used to work with VTK 5.8

I am seeing another error when I try to render:

ERROR: In /Users/aaron/src/VTK/Rendering/VolumeOpenGL/vtkOpenGLRayCastImageDisplayHelper.cxx, line 554

vtkOpenGLRayCastImageDisplayHelper (0x10e3de0c0): failed after RenderTextureInternal 1 OpenGL errors detected

  0 : (1286) Invalid framebuffer operation

Any clues as to what could cause this?  I (not surprisingly) do not see any data displayed, just black pixels.

Thanks,

Aaron
