VTK实现纹理贴图
3星 · 编辑精心推荐
使用VTK导入stl纹理贴图的方法如下:
1. 首先,确保你已经安装了VTK并且设置好了工程。
2. 在代码中引入必要的头文件:
```
#include <vtkSmartPointer.h>
#include <vtkSTLReader.h>
#include <vtkTexture.h>
```
3. 创建一个vtkSTLReader对象,并设置要加载的stl文件路径:
```
vtkSmartPointer<vtkSTLReader> reader = vtkSmartPointer<vtkSTLReader>::New();
reader->SetFileName("path/to/stl/file.stl");
```
4. 创建一个vtkTexture对象,并设置要加载的纹理图片路径:
```
vtkSmartPointer<vtkTexture> texture = vtkSmartPointer<vtkTexture>::New();
texture->SetFileName("path/to/texture/image.jpg");
```
5. 将纹理对象应用到STL模型上:
```
vtkSmartPointer<vtkPolyDataMapper> mapper = vtkSmartPointer<vtkPolyDataMapper>::New();
mapper->SetInputConnection(reader->GetOutputPort());
mapper->Update();
vtkSmartPointer<vtkActor> actor = vtkSmartPointer<vtkActor>::New();
actor->SetMapper(mapper);
actor->SetTexture(texture);
```
6. 创建一个vtkRenderer对象和一个vtkRenderWindow对象,并将actor添加到渲染器中:
```
vtkSmartPointer<vtkRenderer> renderer = vtkSmartPointer<vtkRenderer>::New();
renderer->AddActor(actor);
vtkSmartPointer<vtkRenderWindow> renderWindow = vtkSmartPointer<vtkRenderWindow>::New();
renderWindow->AddRenderer(renderer);
```
7. 创建一个vtkRenderWindowInteractor对象,并启动交互:
```
vtkSmartPointer<vtkRenderWindowInteractor> renderWindowInteractor = vtkSmartPointer<vtkRenderWindowInteractor>::New();
renderWindowInteractor->SetRenderWindow(renderWindow);
renderWindowInteractor->Initialize();
renderWindowInteractor->Start();
```
