MAP-Tk 0.4.1 Released The Motion-Imagery Aerial Phtogrammetry Toolkit (MAP-Tk) is an open-source C++ collection of libraries and tools for making measurements from aerial video. Its initial capability focuses on estimating the camera flight trajectory and sparse 3D point cloud of a scene. This project has similar goals as projects such as Bundler and VisualSFM. However, […]

Introducing GeoJS

October 21, 2014

Introducing GeoJS GeoJS is a new javascript library for visualizing geospatial data in a browser. It is completely open source and is hosted at https://github.com/OpenGeoscience/geojs. We started the project in response to the need for an open-source JavaScript library that can combine traditional geographic information systems (GIS) and scientific visualization on the Web. Many libraries, […]

Kitware News

October 21, 2014

Best Industry-Related Paper Won by Kitware at ICPR 2014 The IEEE/IAPR International Conference on Pattern Recognition (ICPR) is the premier international conference for the latest academic and industry research in pattern recognition on images, video, biomedical data, and other domains. ICPR 2014, the 22nd in the biennial series, was held from August 24 to August […]

This is the third and final part of our trip report on the SciPy 2014 conference, which was held in Austin, TX.  In this post, we will review some of the conference’s interesting workshops, as well as Birds of a Feather (BoF) and sprint sessions. For an introduction and overview of tutorials, please read our […]

Authors: Cesar Palomo, Guillaume Vialaneix, Chris Harris, Claudio Silva,  Aashish Chaudhary In this second article in the ClimatePipes series (please see the part 1 here), we introduce an application that visualizes the effect of climate events on subway usage in New York City. The application can be viewed here: https://climatepipes.kitware.com/apps/subway/web/   Figure 1: The main visualization tool […]

In a previous blog, I covered some of the preliminaries for understanding how VTK’s pipeline works. In this article, we will see the pipeline in action and start dissecting the execution path to understand the inner-workings of algorithms. Let’s start with a very simple pipeline. We’ll use the following code for the source and the […]

In my last two blogs (1, 2), I introduced the vtkPythonAlgorithm and started demonstrating how it can be used to develop sources and algorithms in Python. In those articles, I touched on a few VTK pipeline concepts. For those are not familiar with VTK’s pipeline, this may have been somewhat hard to follow. So in […]

Recently, support for building ParaView using a static Python with NumPy support landed in the ParaView superbuild. In the superbuild, all that is required is to set the BUILD_SHARED_LIBS option to OFF and the superbuild will take care of things from there. What this enables is a single binary for ParaView which has Python and […]

On behalf of the Insight Toolkit Community, we are happy to announce the release of ITK 4.6.1!   This is a patch release that addresses critical issues. The 4.6.1 release fixes DICOM, MetaIO, TIFF, and PNG IO issues, 32-bit WrapITK build errors, Python wrapping warnings, CMake configuration with COMPONENTS, performance and memory consumption of the […]

ParaView 4.2.0 is now available to download. The complete list of over 200 issues resolved for this release can be found the ParaView Bug Tracker. Some of major highlights of this release are as follows: Introducing ParaView Cinema The idea behind Cinema is to process large data in either batch mode or in-situ using Catalyst […]

ParaView Catalyst is a library that adds ParaView analysis and visualization capabilities to a simulation program. For each time step, the simulation code generates data which is passed (using Catalyst’s API) to a ParaView pipeline. This pipeline generates images or processed data that can be saved to disk. Furthermore, data can be exchanged with a remote ParaView […]

This post is the second part of our trip report on the SciPy 2014 conference. It covers the conference’s presentations and posters.  For an introduction and overview of tutorials, please see our previous blog post. Overview This year’s conference expanded the number of talks by approximately 50%. While the talks spanned two days instead of […]

In my last article, I introduced the new vtkPythonAlgorithm and showed how it can be used to developed fully functional VTK algorithms in Python. In this one, we are going to put this knowledge to use and develop a set of HDF5 readers using the wonderful h5py package. First, let’s use h5py to write a series […]

vtkPythonAlgorithm is great

September 10, 2014

Here is the blog I meant to write last time. In this blog, I will actually talk about vtkPythonAlgorithm. I will also cover some VTK pipeline and algorithm basics so those that want to start developing C++ algorithms will also benefit from reading it. As I covered previously, vtkProgrammableFilter is a great tool and useful […]

There are several things new in ParaView 4.2. Lots of changes, both visible and under the covers, have gone into making this an exciting release for the entire team. Not to be left behind, the ParaView Guide is also getting a makeover. While a lot still needs to be done to get the guide ready […]

When I started preparing for this blog, my goal was to write about how awful vtkProgrammableFilter is to use in Python and how the new vtkPythonAlgorithm is superior. Funny enough, as I worked on a few examples, I discovered that vtkProgrammableFilter is not so bad if you know a few tricks. It does what it […]

Background ParaViewWeb is a collection of components that enable the use of ParaView's visualization and data analysis capabilities within Web applications. More specifically, ParaViewWeb uses ParaView to generate data products on the server-side and to rapidly deliver those data products over the Internet to a Web client. ParaViewWeb was developed as a framework used to […]

Continuing covering the improvements to Python tracing capabilities in the upcoming ParaView 4.2, in this post, we’ll see how to control the trace verbosity.   Figure 1: Trace Options Dialog   This is the option under General Settings group called ‘Select which properties to save in trace’. There are 3 options: all properties any modified properties (default) only user-modified properties What this setting […]
