Hi, guys,
I am sorry to jump in your discussion. But I really wish to get some
expertise here to help me with a problem of "Extension GL_VERSION_1_2 could
not be loaded."
I am trying to install a VTK extension for MATLAB - matVTK. When I am
displaying the volume data, MATLAB crashes.
The error message is in display window as follow,
"ERROR: In E:\Download\vtk-5.6.0\Rendering\vtkOpenGLExtensionManager.cxx,
line 341
vtkOpenGLExtensionManager (051B91B8): Extension GL_VERSION_1_2 could not be
loaded."
I think this is a problem of building VTK but I really don't know how to fix
it. How should I link it with OpenGL in Visual Studio? I tried to rebuild it
several times and upgrade the graphics card driver but it doesn't help.
I really wish you could give me some suggestions on this. Thank you and
sorry for interupting your discussion.
