Simulations written in Python or Fortran can now utilize Catalyst 2.0 ! Catalyst 2.0 offers significant advantages over the original implementation including simpler integration to simulations thanks to a small yet powerful API as well as easier deployment due to its ABI-stable design which allows dynamically swapping backends at load-time when launching the simulation. All […]

Thanks to recent developments, the VTKHDF format now supports storing time dependent data in a single HDF5 file. The details of the specification can be found here: https://docs.vtk.org/en/latest/design_documents/VTKFileFormats.html#transient-data, but for convenience, the synthetic diagram is reproduced below in Figure 1. Figure 1: Schematic diagram of the time dependent meta-data in the VTKHDF format The idea […]

3D scene understanding is challenging because of the inherent sparsity property of point-cloud data. In the meantime, 2D image understanding algorithms have already achieved near human-level perception, with a growing research community trying to improve the state of the art. One idea to process 3D data is to actually project it into a 2D view […]

This post is an invited guest blog by: Matthias Ibach, Alexander Straub and Moritz Heinemann researchers at the University of Stuttgart. Multiphase flow simulations: what, why and how? “Any object, totally or partially immersed in a fluid or liquid, is buoyed up by a forceequal to the weight of the fluid displaced by the object.” […]

In the rapidly evolving field of digital pathology, Kitware’s open source software HistomicsTK stands out as a crucial platform for managing and disseminating extensive histopathology data.

The frame selector in the HistomicsUI interface (also available in the Girder interface) allows selecting and compositing channels, z-slices, and other image details.

In today’s data-driven world, the ability to effectively analyze and visualize complex information is crucial. Visual analytics combines analytical reasoning with interactive visual interfaces to facilitate the exploration, analysis, and understanding of complex data and systems. The ability to visually represent data interactively and intuitively allows end-users to discover patterns, trends, and insights that may […]

We are happy to announce the Insight Toolkit (ITK) 5.4 Release Candidate 1 is available for testing! ITK is an open-source, cross-platform toolkit for N-dimensional scientific image processing, segmentation, and registration. Highlights ITK 5.4 is a feature release that continues our modern C++ evolution by requiring C++17. The toolkit progresses in performance with a simple […]

Thirty years ago when the authors of the VTK Textbook began creating what would become the Visualization Toolkit software, a driving motivation for the work was to collaborate with external researchers and the visualization community. To be honest, at that time we didn’t really understand how important adopting an open-source license would be. And we […]

CMake 3.27.0 available for download

The fifth CMake 3.27 release candidate!

In our previous article, we described how our team at Kitware developed Cell Locator, an annotation tool that uses 3D Slicer to locate brain samples in 3D reference atlases. Cell Locator integrates with the workflow of the Allen Institute for Brain Science and supports neuroscience research by enabling annotations of experimental results.  While Cell Locator […]

The fourth CMake 3.27 release candidate!

The vtk.js web rendering platform now allows you to render augmented reality visualizations on head-mounted display devices (AR HMDs). Developers can use vtk.js to create custom applications that run directly on AR-capable headsets, including the Microsoft Hololens 2, Meta Quest 2, and the upcoming Apple Vision Pro, without being tethered to a computer.

Kitware note: This is a guest blog from Julien Tierny, from Sorbonne Université, Paris, France and Fabien Vivodtzev from CEA, France The Topology ToolKit (TTK)[1,2] is an open source library for Topological Data Analysis and Visualization. It provides a substantial collection of generic, efficient and robust implementations of key algorithms in topological data analysis. It […]
