Hello everyone,
I am a beginner to VTK.I’m trying to volume render with vtk C++ in VS.
My teacher sent me a txt file and asked me to perform volume rendering on the data inside.
In the past few days, I have studied some VTK cases and successfully rendered some .vtk and .mhd format documents.But I don’t know how to process txt format documents.
The document content is as follows：
Model data only knows size：100100240
What should I do with this data？Thanks！！
You can read the text file into a buffer using STL filestream and then use vtkImageImport to set the buffer as the scalar array on a vtkImageData.
This is my script：
std::ifstream file(“data501.txt”);
std::vectordata;
float value;
while (file>>value)
{
data.push_back(value);
}
vtkSmartPointer<vtkImageData>imagedata =
vtkSmartPointer<vtkImageData>::New();
imagedata->SetDimensions(100, 100, 240);
imagedata->AllocateScalars(VTK_FLOAT,1);
And then what should I do？Thank you very much
