Search for Python

On April 24, 2014, Casey Goodlett attended the Triangle Python Users Group Meeting held in Carrboro, NC. During the meeting, Casey presented a talk on “Python Scripting of ParaView with Application to Point Cloud Processing,” which detailed use cases in point cloud processing to exemplify how Python can be used to implement domain-specific visualization and […]

Studying examples is an excellent way to learn, especially for scientific software.  An example demonstrates explicitly how a concept works or how a given objective can be achieved. When code is coupled with documentation, all the critical details, which are difficult to encapsulate in prose, are immediately evident. Following on the outstanding work by lead David Doria […]

A class of Earth Science students from RPI visited Kitware today with their instructor Steve Signell, who is teaching GIS at RPI, to learn about some of Kitware’s open-source visualization tools and capabilities. During their visit, Aashish Chaudhary talked to the students about Kitware, open source, and ongoing climate and geospatial projects. He showed them a video […]

VTK 6.1.0 Released Kitware and the entire VTK team are happy to announce the release of VTK 6.1.0. The release fixes bugs and adds features on top of the more modular code structure of version 6.0. The source, data, and new vtkpython binary packages can be downloaded from VTK’s website. This release introduces the vtkDax […]

Project configuration in software development is the process of setting up “how” your code will be built, managed, and/or run. It varies depending on the programming language and tools used, such as the IDE. For instance, when programming in C/C++, the project setup usually entails defining what artifacts (e.g., executables, libraries) will be built from […]

This article describes the process of packaging VistA for the Debian Linux distribution. It begins with our rationale and motivation and continues with a discussion on the collaboration process that followed with many members of the open-source community. What is VistA?  The Veterans Health Information Systems and Technology Architecture (VistA) is the most comprehensive Electronic […]

At present, the majority of the climate science community still relies heavily on primitive analysis and visualization tools that are based on the thick (or fat) client application concept. This means that the user must download software to the appropriate machines or hardware where the data resides (e.g., laptops, desktops, or HPC machines). In such […]

I am proud to announce the CMake 3.0 third release candidate. Sources and binaries are available at:   http://www.cmake.org/files/v3.0/?C=M;O=D Documentation is available at:   http://www.cmake.org/cmake/help/v3.0 Release notes appear below and are also published at   http://www.cmake.org/cmake/help/v3.0/release/3.0.0.html Some of the more significant features of CMake 3.0 are: Compatibility options supporting code written for CMake versions prior to 2.4 have […]

Have you ever used the vtkHyperOctreeLimiter filter in ParaView? As far as I know, I haven’t. I’m not saying it’s not a useful filter, just that it’s not useful to me for what I use ParaView for. For that matter, there’s a bunch of stuff in ParaView that I don’t regularly use. When I’m building […]

Kitware is pleased to announce the release of SimpleITK 0.8.0. SimpleITK is a simplified layer built on top of ITK. By providing binaries for several wrapped languages, it facilitates ITK’s use in rapid prototyping, education, and interpreted languages. The 0.8.0 release includes several improvements to SimpleITK including support for events and command call-backs and support […]

ParaView is not a small project. It includes over 3 million lines of C and C++ code and 250,000 lines of Python with a smattering of other languages such as FORTRAN, Tcl, and Java (accoring to the wonderful sloccount tool) in its build, and the build has more than 18,000 things to do when Python […]

Testing sofware with Graphcical user interfaces (GUIs) can be more challenging than testing command line software. This is because GUIs require a mouse or other human interface system to drive them. Tesing a GUI involves being able to record human interactions and play them back later. There are a variety of tools available for GUI testing, but many […]

Kitware hosted the second VTK hackathon on Tuesday, January 28th, at Kitware’s headquarters in Clifton Park, NY. The hackathon was a follow-up to last February’s very successful “dashathon” event in which the group successfully targeted persistent problems in the regression test suite. The topic of the second hackathon was to increase the test coverage metric, […]

Motivation The View Settings dialogs allow you to set view specific parameters such as background color and type of lighting for a 3D View or font and color of axis labels for a Bar Chart View. These dialogs use their own names and specify their own defaults for view properties. This way of naming properties and setting their […]

Kitware and the entire VTK team are happy to announce that VTK 6.1.0 is ready for release. VTK 6.1.0 fixes bugs and adds features on top of the more modular code structure of version 6.0. The source, data, and new vtkpython binary packages can be downloaded from VTK’s website. VTK continues to evolve to make […]

ITK 4.5.0 Released The ITK 4.5 release is a major milestone that marks the hard work of many outstanding community members. Among the major contributions in this release are registrations computed with 32-bit floats, a new edition of the Software Guide, the first release of the wiki examples tarball, and the first release of the […]

At the Core Technologies team at Netflix, we develop the application framework and streaming engine used by millions of consumer electronics devices, game consoles, tablets, and phones. With such a diverse array of devices and platforms, we need to make sure our code is lightweight, standards compliant, and portable. As we also produce the SDK […]
