<!--SOHUMAIL_HTML_HEAD_END-->Hello all,<p><p>I have a trouble in the display of a model now.<p>The environment is MS Visual C++ 6.0.<p>And it is a MFC project(Doc-View).<p>The key codes are:<p><p>In the Doc:<p><p> vtkRenderer *ren;<p> vtkWin32OpenGLRenderWindow *renWin;<p> vtkWin32RenderWindowInteractor *renWinInter;<p> vtkCubeSource *cube;<p> vtkPolyDataMapper *cubeMapper, *AxesMapper;<p> vtkActor *cubeActor,*myAxesActor;<p> vtkCubeAxesActor2D *axesActor;<p> vtkAxes *myAxes;<p> vtkCamera *myCamera;<p> vtkLight *myLight1, *myLight2;<p> BOOL m_bIsThreeDimension;<p><p> then:<p><p> m_bIsThreeDimension=TRUE;<p><p> this->ren=vtkRenderer::New();<p> this->renWin=vtkWin32OpenGLRenderWindow::New();<p> this->renWinInter=vtkWin32RenderWindowInteractor::New();<p> this->cube=vtkCubeSource::New();<p> this->cubeActor=vtkActor::New();<p> this->cubeMapper=vtkPolyDataMapper::New();<p> this->axesActor=vtkCubeAxesActor2D::New();<p> <p> this->myAxes=vtkAxes::New();<p> this->AxesMapper=vtkPolyDataMapper::New();<p> this->myAxesActor=vtkActor::New();<p> <p> this->myCamera=vtkCamera::New();<p> <p> this->myLight1=vtkLight::New();<p> this->myLight2=vtkLight::New();<p> this->renWin->AddRenderer(this->ren);<p> this->renWinInter->SetRenderWindow(this->renWin);<p> this->cubeMapper->SetInput(this->cube->GetOutput());<p> this->cubeActor->SetMapper(this->cubeMapper);<p> this->cubeActor->GetProperty()->SetColor(0.9804,0.5020,0.4471);<p> this->cubeActor->SetPosition(/*0.475,0.475,0.475*//*1,1,1*/0,0,0);<p> this->ren->AddActor(this->cubeActor);<p> this->AxesMapper->SetInput(this->myAxes->GetOutput());<p> this->myAxesActor->SetMapper(this->AxesMapper);<p> this->myAxesActor->GetProperty()->SetColor(1,0,0);<p> this->myAxesActor->SetPosition(0,0,0);<p> this->ren->AddActor(this->myAxesActor);<p> <p> this->myLight1->SetColor(1,1,1);<p> this->myLight1->SetFocalPoint(0,0,0);<p> this->myLight1->SetPosition(10,15,20);<p> this->ren->AddLight(this->myLight1);<p> this->myLight2->SetColor(1,1,1);<p> this->myLight2->SetFocalPoint(0,0,0);<p> this->myLight2->SetPosition(-10,-15,-20);<p> this->ren->AddLight(this->myLight2);<p> <p> this->myCamera->SetViewUp(0,0,1);<p> this->myCamera->SetFocalPoint(0,0,0);<p> this->myCamera->SetPosition(10,15,10);<p> this->ren->SetActiveCamera(this->myCamera);<p><p>View::OnCreate(LPCREATESTRUCT lpCreateStruct)<p>{<p> this->GetDocument()->renWin->SetParentId(this->m_hWnd);<p> this->GetDocument()->myCamera->SetViewUp(0,0,1);<p> this->GetDocument()->myCamera->SetFocalPoint(0,0,0);<p> this->GetDocument()->myCamera->SetPosition(10,15,10);<p> this->GetDocument()->ren->SetActiveCamera(this->GetDocument()->myCamera);<p><p> return 0;<p>}<p><p>View::OnDraw(CDC* pDC)<p>{<p> if (this->GetDocument()->m_bIsThreeDimension)<p> { <p> CRect rect;<p> this->GetClientRect(&rect);<p> this->GetDocument()->renWinInter->Initialize();<p> this->GetDocument()->renWin->SetSize(rect.right-rect.left,rect.bottom-rect.top);<p> this->GetDocument()->ren->ResetCamera();<p> this->GetDocument()->renWin->Render();<p> }<p>}<p><p>But after calling a function in the Doc to make "m_bIsThreeDimension=FALSE" and "UpdateAllViews(NULL)", the model is still displaying and inter-actable.<p>My question is why the model is still displaying after leaping over the codes:<p>"<p> CRect rect;<p> this->GetClientRect(&rect);<p> this->GetDocument()->renWinInter->Initialize();//绘制的重要函数<p> this->GetDocument()->renWin->SetSize(rect.right-rect.left,rect.bottom-rect.top);<p> this->GetDocument()->ren->ResetCamera();<p> this->GetDocument()->renWin->Render();<p>"?<p>How can I make the model not display in the view under the condition of not deleting any object defined.<p><p><p>Thanks and regards<hr size=1><style type="text/css">
