要在C++中结合VTK( Visualization Toolkit )创建一个固定的、位于屏幕右上角的正方体,并且支持鼠标悬浮高亮显示和点击切换视角,你需要首先安装并设置VTK环境,然后编写一些核心的VTK代码。以下是一个简化的示例,展示了如何创建这个场景:
```cpp
#include <vtkSmartPointer.h>
#include <vtkRenderer.h>
#include <vtkRenderWindow.h>
#include <vtkRenderWindowInteractor.h>
#include <vtkActor.h>
#include <vtkPolyDataMapper.h>
#include <vtkCubeSource.h>
#include <vtkProperty.h>
#include <vtkInteractorStyleTrackballCamera.h>
class MyInteractorStyle : public vtkInteractorStyleTrackballCamera {
public:
// ... (Override necessary methods for mouse hover and click events)
};
int main(int argc, char *argv[]) {
// 创建渲染窗口和交互式窗口
vtkSmartPointer<vtkRenderWindow> renWin = vtkSmartPointer<vtkRenderWindow>::New();
renWin->SetSize(500, 500);
renWin->SetPosition(100, 100); // 设置在屏幕右上角
// 创建渲染器
vtkSmartPointer<vtkRenderer> renderer = vtkSmartPointer<vtkRenderer>::New();
renWin->AddRenderer(renderer);
// 创建立方体贴图数据源
vtkSmartPointer<vtkCubeSource> cubeSource = vtkSmartPointer<vtkCubeSource>::New();
cubeSource->Update();
// 创建mapper和actor
vtkSmartPointer<vtkPolyDataMapper> mapper = vtkSmartPointer<vtkPolyDataMapper>::New();
mapper->SetInputConnection(cubeSource->GetOutputPort());
vtkSmartPointer<vtkActor> actor = vtkSmartPointer<vtkActor>::New();
actor->SetMapper(mapper);
// 高亮显示属性
actor->GetProperty()->SetColor(1, 0, 0); // 红色表示高亮
actor->GetProperty()->SetOpacity(0.7); // 设置透明度
// 添加到渲染器
renderer->AddActor(actor);
// 设置交互样式
MyInteractorStyle *interactorStyle = new MyInteractorStyle;
renWin->SetInteractorStyle(interactorStyle);
// 开始交互
vtkSmartPointer<vtkRenderWindowInteractor> iren = vtkSmartPointer<vtkRenderWindowInteractor>::New();
iren->SetRenderWindow(renWin);
iren->Start();
return EXIT_SUCCESS;
}
// ... (Implement mouse hover and click event handlers in MyInteractorStyle)
