vtk

问题 I'm trying to link VTK library to my project on Windows 7. The error I get is: Error C1083 Cannot open include file: 'vtkGUISupportQtOpenGLModule.h': No such file or directory The thing in my code that provokes the error is #include<QVTKWidget2.h> . Src and build directories of my VTK copy are separate. The linking tool I use is cmake . The build tool: VS 2015 . My CMakeLists.txt and VTK's cache u can see below. Thanks in advance for any suggestions. CMakeLists.txt cmake_minimum_required

问题 I need to install VTK and mayavi on Ubuntu 16. I have Anaconda with Python 3.6. If I run: conda install -c menpo vtk=7.0.0 vtk I get: Fetching package metadata ........... Solving package specifications: . UnsatisfiableError: The following specifications were found to be in conflict: - python 3.6* - vtk 7.0.0* -> python 3.5* -> openssl 1.0.1* - vtk 7.0.0* -> python 3.5* -> xz 5.0.5 Use "conda info <package>" to see the dependencies for each package. Apparently, I need Anaconda with Python3.5,

问题 I'm trying to install VTK module for python, I am however unsuccesful in doing so. I have downloaded a VTK tar-file, but I'm unable to extract it. I'm capable of extracting other tar-files, so there must be something specific with this file I suppose. This is my error: gzip: stdin: invalid compressed data--format violated tar: Child returned status 1 tar: Error is not recoverable: exiting now I hope somebody can help me with this. 回答1: The answer depends on the operating system you are using.

问题 I'm trying to use vtk in my code, but I'm having problems running an example. I have almost no clue about the reasons since it's the first time I'm using it and I'm not very experienced. I'm using visual studio 2012 and x64 platform. Since I don't really know which libs should I use I added all of them to the "Additional Dependencies". The example is given in this link. The problem is that when I run it, the window shows this message Generic Warning: In C:\location\VTK6.0.0\Rendering\Core

问题 I'm trying to make a video of the trajectories of particles. However, somehow my scene never updates. Here's a very simple example: from __future__ import absolute_import, division, print_function from mayavi import mlab import numpy as np import math alpha = np.linspace(0, 2*math.pi, 100) xs = np.cos(alpha) ys = np.sin(alpha) zs = np.zeros_like(xs) mlab.points3d(0,0,0) plt = mlab.points3d(xs[:1], ys[:1], zs[:1]) @mlab.animate(delay=100) def anim(): f = mlab.gcf() while True: for (x, y, z) in

问题 Reading netcdf files with Paraview using xdmf I used to parse netcdf files with an xdmf script in order to create 3DSMesh on paraview. On top of it, I was adding scalar or vector fields. (So 3DSMesh provides physical coordinates). I never though if it is best way to do that actually. It works, so I was OK. Please let me know if there is more convenient way. I am able to create a 3-dimensional grid with the following script. <?xml version="1.0" ?> <!DOCTYPE Xdmf SYSTEM "Xdmf.dtd" []> <Xdmf

问题 I am working on a file whose endian is different from my desktop and I need to convert it, but When I visualized the vtk it worked. So are vtkreaders of vtk files endian independent 回答1: ParaView can read VTK files written using either big- or little-endian byte ordering and will try to work out which format has been used when writing a given file. From the VTK File format documentation: Binary Files. Binary files in VTK are portable across different computer systems as long as you observe

问题 I've been trying to do animation with VTK, so I've been using TimerEvent. When I tried to move over to the Qt binding, it broke. The problem is that as soon as I interact with the view (say scrolling to zoom, or clicking to rotate) the timer stops. Here's a simple minimal example: import vtk from vtk.qt.QVTKRenderWindowInteractor import QVTKRenderWindowInteractor from PyQt5 import Qt message = "tick" def onTimerEvent(object, event): global message print(message) if message == "tick": message

问题 I would like to combine multiple Mayavi objects into a single "grouped" object so that I control all of their properties together. For example I created the following bi-convex lens shape by combining 3 built-in surfaces (two spheres and one cylinder). Now I would like to assign uniform properties (specularity, ambient color, etc) to all of the constituent surfaces at a time (not individually). Also, I would like to translate/rotate the lens as a whole. I am not sure how to accomplish this.

问题 In VTK I am able to use the following snippet to save the render window as an image. However, actually I want to get it directly as a numpy array (without writing then reading). im = vtkWindowToImageFilter() writer = vtkPNGWriter() im.SetInput(renderWindow) im.Update() writer.SetInputConnection(im.GetOutputPort()) writer.SetFileName("file.png") writer.Write() What is the best way to do this? 回答1: I believe there is no need to involve vtkXWriter (where X is some format), except if you need the
