SIAM’s Computational Science and Engineering (CSE) conference was held this year in Salt Lake City. Over one thousand people attended the conference, which featured minisymposia, minitutorials, and keynote addresses. The conference had a lot to offer, and Kitware participated in several activities. On the first day of the conference, Bill Hoffman and Andy Bauer attended […]

VTK 6.2.0 Released The VTK development team is pleased to announce that VTK 6.2.0 is ready for download. In this release, VTK’s use of parallelism in modern architectures continues to mature. In terms of managing pieces and extents in the pipeline, for example, VTK’s readers are now responsible for implementing translation, and its parallel filters […]

Testing in the Cloud The flexibility of cloud computing platforms can be leveraged to provide scalable continuous integration testing. Using cloud computing resources effectively, however, requires the coordination of a robust software infrastructure. When a developer on a large open-source project finishes a draft of a patch, he or she should not have to wait […]

Climate Data Analysis Team Receives Award & Releases New Project Version The development team for the project “Ultrascale Visualization Climate Data Analysis Tools (UV-CDAT)” was recently selected as the 2015 recipient of the National Federal Laboratory Consortium for Technology Transfer’s (FLC) Interagency Partnership Award. The selection came shortly after the release of UV-CDAT version 2.1.0. […]

MAP-Tk 0.5.0 Release The MAP-Tk 0.5.0 release offers new functionality including preliminary support for essential matrix estimation and camera initialization algorithms. It further updates the bundle adjustment tool to estimate a similarity transformation to place results in a canonical coordinate system when external constraints are not provided on position, orientation, and scale. In addition, the […]

The VTK development team is happy to announce that VTK 6.2.0 is ready. Special thanks go out to everyone who tested and provided input and fixes during the release candidate cycle. You can find the source, data, and vtkpython binary packages here: http://www.vtk.org/VTK/resources/software.html VTK’s use of the parallelism available in modern architectures continues to mature.

One of the things I really love about working on open-source projects is seeing where people take the things I’ve worked on. The latest example of this that just blew me away was with a CFD code called PHASTA, led by Ken Jansen at UC Boulder. Short for Parallel Hierarchic Adaptive Stabilized Transient Analysis, six […]

On behalf of the Insight Toolkit Community, we are happy to announce the release of ITK 4.7.1! Get it now! This is a patch release that addresses critical issues, regressions, important documentation, and compiler support. The 4.7.1 release fixes improves Visual Studio support, addresses Python wrapping runtime warnings, includes fixes for the ITK Software Guide, […]

VTK 6.2 has entered the release candidate stage. You can find the source, data, and new vtkpython binary packages here:   http://www.vtk.org/VTK/resources/software.html#latestcand   Please try this version of VTK and report any issues to the list or the bug tracker so that we can try to address them before VTK 6.2.0 final.     Some […]

Editors Note: In 2017/2018 Google shut down Project Tango in favor of ARCore. While ParaView is under active development, and Kitware still does a lot of work with point clouds, we no longer have working versions of the Project Tango device APKs referenced in this post. Introduction We use ParaView for many of our our […]

We recently added new functionality to ParaView to support interacting with the view when using pvpython. This is supported as of nightly version (v4.3.1-122-g1a5724d) and will included in the next stable release (version 4.4). Previously, users could not interact with any Render View, or Bar Chart View etc., when running pvpython or pvbatch. While it still doesn't make sense to support interaction when […]

VTK has long evolved beyond just visualization. It offers some amazing functionality that just cannot be found elsewhere. Two examples are the ‘ray-casting’ and, consequentially, ‘ray-tracing’ capabilities provided by the vtkOBBTree class. In this article, I would like to introduce these capabilities and show examples of ray-casting and ray-tracing performed exclusively through Python, a dash […]

Over the past two years, we have been developing Tangelo [1] in the pursuit of rich web applications for solving problems, both old and new. We recently passed 2,000 commits in the repository [2], and Tangelo will soon be ready for prime time. This article aims to inform you more about the technology with a […]

Dr. Hoogs Presents Computer Vision Papers at IEEE Workshop Dr. Anthony Hoogs, Kitware's Senior Director of Computer Vision, presented three papers at the 2014 IEEE Applied Imagery and Pattern Recognition (AIPR) Workshop. The workshop was held in Washington, DC, from October 14 to October 16, 2014. For "Multi-Target Tracking in Video with Adaptive Integration of […]

This is it. My last blog on streaming, at least for a while. Looking back, I have been writing about the VTK pipeline and how it can be leveraged to do cool things since September. This will be a cool topic to wrap this series up with. In the last blog, I demonstrated how to […]

Introduction This is the first in a series of articles that describe how Sphinx has been extended to create a powerful example documentation system, the ITK Sphinx Examples. For previous posts, see Part I: Credits via GitStats Part II: WebGL Visualizations Doxygen is the de facto standard tool for generating documentation from annotated C++ sources, and it […]

Want to learn medical image analysis? Check out material from the following recent undergraduate and graduate courses where the Insight Toolkit (ITK) and the simplified interface to ITK, SimpleITK, were applied. Methods in Medical Image Analysis, University of Iowa This semester long course taught by Hans Johnson is an excellent introduction to medical image analysis and ITK. The course […]

We are taking a quick break from the series of blogs on streaming. Instead, in preparation for a discussion on block-based streaming, I will discuss how you can write multi-block unstructured grid readers and writers in Python using the h5py library. Let’s get right down business. Here is the writer code. import vtk import h5py […]
