VTK纹理比例

Question

我正在处理眼睛图像，我想做的就是拍摄其中一张图像并将其作为球体的纹理应用。但是，我在缩放时遇到了一些麻烦，这是到目前为止的外观：

这是我正在使用的图像：

到目前为止，我已经尝试了各种方法，但是仍然没有得到想要的结果。

这是我一直在努力的代码：

#include <vtkSmartPointer.h>
#include <vtkRenderWindowInteractor.h>
#include <vtkRenderWindow.h>
#include <vtkRenderer.h>
#include <vtkActor.h>
#include <vtkPolyDataMapper.h>
#include <vtkTransformTextureCoords.h>
#include <vtkTexture.h>
#include <vtkTextureMapToSphere.h>
#include <vtkImageReader2Factory.h>
#include <vtkImageReader.h>
#include <vtkTexturedSphereSource.h>
#include <vtkSphereSource.h>

int main(int argc, char *argv[])
{
std::string fileName = "C:\\VTK\\eyeTextureNew2.jpg";

//Create sphere
vtkSmartPointer<vtkTexturedSphereSource> source =
    vtkSmartPointer<vtkTexturedSphereSource>::New();
source->SetPhiResolution(100);
source->SetThetaResolution(100);

// Read texture file
vtkSmartPointer<vtkImageReader2Factory> readerFactory =
    vtkSmartPointer<vtkImageReader2Factory>::New();
vtkImageReader2 *imageReader = readerFactory->CreateImageReader2(fileName.c_str());
imageReader->SetFileName(fileName.c_str());

// Create texture
vtkSmartPointer<vtkTexture> texture =
    vtkSmartPointer<vtkTexture>::New();
texture->SetInputConnection(imageReader->GetOutputPort());

vtkSmartPointer<vtkTransformTextureCoords> transformTexture =
    vtkSmartPointer<vtkTransformTextureCoords>::New();
transformTexture->SetInputConnection(source->GetOutputPort());

vtkSmartPointer<vtkPolyDataMapper> mapper =
    vtkSmartPointer<vtkPolyDataMapper>::New();
mapper->SetInputConnection(transformTexture->GetOutputPort());

vtkSmartPointer<vtkActor> actor =
    vtkSmartPointer<vtkActor>::New();
actor->SetMapper(mapper);
actor->SetTexture(texture);

vtkSmartPointer<vtkRenderer> renderer =
    vtkSmartPointer<vtkRenderer>::New();
renderer->AddActor(actor);
renderer->SetBackground(.1, .2, .3);

vtkSmartPointer<vtkRenderWindow> renderWindow =
    vtkSmartPointer<vtkRenderWindow>::New();
renderWindow->AddRenderer(renderer);

vtkSmartPointer<vtkRenderWindowInteractor> renWinInteractor =
    vtkSmartPointer<vtkRenderWindowInteractor>::New();
renWinInteractor->SetRenderWindow(renderWindow);

renderWindow->Render();
renWinInteractor->Start();

imageReader->Delete();

return EXIT_SUCCESS;
}

关于我可能做错/遗漏的任何想法？预先感谢！

用vtkplotter我得到了（但背面对称）：

4.1.*

4.1.0函数实际上是这样做的：

    from vtkplotter import Sphere

    s = Sphere().texture('QeXKq.jpg')
    s.show()
