vtk

问题 I've this TOF-sensor and I want to visualize the sensor's data as a point-cloud in Qt. I converted the data into a pcl::PointCloud and now I want to visualize it. The API of the sensor would emit a picture whenever one was created. And I would send it to the QVTKWidget to visualize it. And I tried it with this snippet of code (which I got from here): pcl::visualization::PCLVisualizer pvis ("test_vis", false); // 'false' prevents PCLVisualizer's own window to pop up pvis.addPointCloud<pcl:

问题 I am trying to write a basic binary VTK file to display some data using ParaView but I have some errors and I don't understand why. Here is my test code in C++: #include <iostream> #include <fstream> double myarray[72] = { 0,0,0,1,0,0,2,0,0,3,0,0,4,0,0, 5,0,0,0,1,0,1,1,0,2,1,0,3,1,0, 4,1,0,5,1,0,0,2,0,1,2,0,2,2,0, 3,2,0,4,2,0,5,2,0,0,3,0,1,3,0, 2,3,0,3,3,0,4,3,0,5,3,0}; int main() { std::ofstream vtkstream("test01.vtk", std::ios::out | std::ios::trunc); bool ascii = false; if (vtkstream) {

问题 I successfully built and installed VTK-5.4 with Python bindings from source. Yet, when I try to import VTK in python it gives the following Traceback error File "", line 1, in File "/usr/local/lib/python2.6/dist-packages/VTK-5.4.2-py2.6.egg/vtk/ init .py", line 41, in from common import * File "/usr/local/lib/python2.6/dist-packages/VTK-5.4.2-py2.6.egg/vtk/common.py", line 7, in from libvtkCommonPython import * ImportError: libvtkCommonPythonD.so.5.4: cannot open shared object file: No such

问题 I need to use the VTK library (with version 5.10 because I am working on an existing code) in python on my Windows 10 machine but I can not manage to import it without DLLImport error: Python 2.7.12 (v2.7.12:d33e0cf91556, Jun 27 2016, 15:19:22) [MSC v.1500 32 bit (Intel)] on win32 Type "help", "copyright", "credits" or "license" for more information. >>> import vtk Traceback (most recent call last): File "<stdin>", line 1, in <module> File "C:\Python27\lib\site-packages\vtk\__init__.py", line

问题 I am trying to copy a vtkImageData* class to a cv::Mat structure [my goal is to read an MHD file into OpenCV].. The file is essentially a 3D Matrix so I want to get a vector containing all the slices of the volume. So far, I have come up with this code, reader->SetFileName(INPUT_DATA_1.c_str()); reader->Update(); imageData_1 = reader->GetOutput(); extractVOI->SetInput(imageData_1); int dims[3]; imageData_1->GetDimensions(dims); extractVOI->SetVOI(0, dims[0], 0, dims[1], 75, 75); // Set it to

问题 I have a set of 3D points which I've used scipy.spatial.Delaunay to do the triangulation / tetrahedralization. I now have a set of unique faces of all of the tetrahedra, and would like to visualize these in 3D. Are there any Python libraries (or libraries with a Python wrapper) that can do this? 回答1: Try mayavi.mlab.triangular_mesh() import numpy as np from mayavi import mlab vertices = np.array([[0, 1, 0, 0],[0, 0, 1, 0],[0, 0, 0, 1]]) faces = np.array([[0, 1, 0, 0],[1, 2, 1, 2],[2, 3, 3, 3]

问题 I'm trying to save three sets of vector quantities corresponding to the same structured grid (velocity, turbulence intensity and standard deviation of velocity fluctuations). Ideally, I'd like them to be a part of the same vtk file but so far I have only been able to get one of them into the file like so: sg = tvtk.StructuredGrid(dimensions=x.shape, points=pts) sg.point_data.vectors = U sg.point_data.vectors.name = 'U' write_data(sg, 'vtktestWake.vtk') I've spent past few hours searching for

问题 I'm trying to compile a program in CMake but I'm getting this error. By not providing "FindVTK.cmake" in CMAKE_MODULE_PATH this project has asked CMake to find a package configuration file provided by "VTK", but CMake did not find one. Could not find a package configuration file provided by "VTK" (requested version 6.1) with any of the following names: VTKConfig.cmake vtk-config.cmake I can't find the relevant files (VTKConfig.cmake or vtk-config.cmake) on the machine but do have VTKConfig

问题 I'm getting started with vtk (6) in python and have a problem handling KeyPressEvent. I want to subclass the vtkInteractorStyleTrackballCamera if I use this pattern, my interactor style does not have getKeySym() and I can't decode what key was pressed class KeyPressInteractorStyle(vtk.vtkInteractorStyleTrackballCamera): def __init__(self,parent=None): self.AddObserver("MiddleButtonPressEvent",self.middleButtonPressEvent) self.AddObserver("MiddleButtonReleaseEvent",self

问题 I am just learning VTK (and C++ GUI programming) and have hopefully simple question. The main application launches rendered window at some point in application. Would like to be able for the main thread to continue, while VTK window is displayed. Is there a particular method to launch VTK window as a thread? My environment is Linux, with boost and pthreads at my disposal. Thanks. VTK is visualization toolkit, see vtk.org 回答1: You can call vtkRenderWindowInteractor->Start() method. (Get the
