Hi,all,

    I turned on immediate mode rendering on the mappers(m_Mapper-ImmediateModeRenderingOn()). But there is still not enough speed to display my object.In my program,I must updata some objects in vtkRenderWindow and re_rendering the vtkRenderWindow use m_vtkRenderWindow->Render.So the speed is slow.How can I improve the speed of this?

Thanks!
