VTK Render into C#

我有一个使用VTK的c++应用程序,我想要vtkRenderWindow并将其放入c# WPF项目中,而不使用c#包装器
这样做的主要思想是将HWND设置为vtkRenderWindow的父节点
方法如下:c++类:
class MyRender
{
//attributes
....
MyRender(HWND parent)
{
renderer = vtkSmartPointer<vtkRenderer>::New();
_render = vtkSmartPointer<vtkRenderWindow>::New();
_render->AddRenderer(renderer);
interactor = vtkSmartPointer<vtkRenderWindowInteractor>::New();
interactor->SetRenderWindow(_render);
//setting background
renderer->SetBackground(0.1, 0.2, 0.4);
_render->SetParentId(parent);
}
void Render()
{
interactor->Initialize();
_render->Render();
}
//...more methods
}
创建CLR类来包装c++类,格式如下:
class RenderWindows_CLR
{
//attributes
MyRender* renderWindow;
RenderWindows_CLR::RenderWindows_CLR::RenderWindows_CLR(IntPtr parent)
{
renderWindow = new MyRender((HWND)parent.ToPointer());
}
void RenderWindows_CLR::RenderWindows_CLR::Render(IntPtr parent)
{
renderWindow->Render();
}
}
如何在c#中使用它:下面是如何放置在Windows窗体面板的位置:
window = new RenderWindows_CLR.RenderWindows_CLR(this.panel.Handle);
window.Render()
下面是如何使用WPF:
HwndSource source = (HwndSource)HwndSource.FromVisual(this);
IntPtr hWnd = source.Handle;
window = new RenderWindows_CLR.RenderWindows_CLR(hWnd);
要删除标题栏,只需在c++ DLL中添加以下内容(在创建渲染窗口之后):
HWND window = (HWND)_render->GetGenericWindowId();
LONG style = GetWindowLong(window, GWL_STYLE) & ~(WS_BORDER | WS_DLGFRAME | WS_THICKFRAME);
SetWindowLong(window,-16L, style);
