Hello,<br>my Windows Application crashes when calling <br>vtkRenderWindowInteractor::Render() the first time during initialization.<br>This happens only with the official VTK 5.6 version but not with the older<br>VTK 5.2. <br>
According to the debugger, the procedure GenBuffers has address 0, and thats why the app crashes.<br>Here is the VTK code of the method where the crash happens : (bottom of stack trace)<br><br><br>void vtkPixelBufferObject::CreateBuffer()<br>
{<br> this->Context->MakeCurrent();<br> if (!this->Handle)<br> {<br> GLuint ioBuf;<br> vtkgl::GenBuffers(1, &ioBuf); ///// crash -- GenBuffers is 0 !<br> vtkGraphicErrorMacro(this->Context,"after GenBuffers");<br>
this->Handle = ioBuf;<br> }<br>}<br><br>Any help would be greatly appreciated.<br><br>Best Regards,<br>Oliver <br><br><br>
