3D Slicer 5.12 is now available. This latest stable release includes updates to DICOM workflows, visualization, Python package management, Qt 6 build support, and the extension ecosystem. Slicer 5.12 serves as a stable release before the project continues broader work related to Qt 6 and native Apple Silicon support.

CMake 4.4.0 available for download

Kitware is pleased to be returning to the Microscopy & Microanalysis (M&M) conference. This year, we will be exhibiting and hosting a vendor tutorial about the Tomviz 3.0 release. We also had a platform presentation accepted on our DOE Phase II-funded open source multivariate visualization work. Visit us at Booth #1222 to learn more, or contact our team to schedule a meeting.

The third CMake 4.4.0 release candidate!

CMake 4.3.4 available for download

Kitware presents a trame-based web application to configure battery simulations.

The second CMake 4.4 release candidate!

This blog describes the workflow in which Kitware is involved in the European project Marine Beacon and the tools developed for the consortium of researchers to deploy embedded AI models for active fishery monitoring, aiming to reduce bycatch. It will go through the web platform, enabling the upload and sharing of annotated data and models […]

Polyhedral cells (general convex or non-convex 3D cells with arbitrary face and vertex counts) appear throughout large-scale simulation, particularly in CFD. Some solvers produce them as the dual of a tetrahedral mesh; others use them as transition cells across refinement boundaries; still others build directly on face-based polyhedral connectivity as the native primitive. Several commercial and open source CFD codes have invested in face-based arbitrary polyhedral cells as a first-class primitive, and that investment runs all the way through the pre- and post-processing pipeline because handling polyhedra well at every stage is non-trivial.

Kitware announces the release of trame-gwc, a Python package that exposes Girder capabilities to trame-based applications.

Live visualizing simulation data can be difficult and costly: the data needs to be saved to disk periodically to be analyzed in order to create meaningful images. What if you wanted to monitor your simulation across multiple devices without installing anything locally? What if you wanted to do all of that without spending hours saving simulation data on the disk? Let’s see how it can be done using Kitware’s technologies.

Bug fixes made since ParaView 6.1.0 are listed in this document. The full list of issues addressed by this patch release is available here. Screenshot to clipboard fixed ParaView now properly supports screenshoting to clipboard, which was not working in v6.0.X. (details) Incorrect Above Range Color and Below Range Color mapping in color legend fixed […]

Medical imaging AI research often runs into a familiar bottleneck: the data exists, but security requirements make it unusable. Sensitive datasets are: Over the past three years, Kitware has worked closely on a self-hosted medical image annotation deployment designed to address this challenge. The result is a secure platform that keeps sensitive data fully within […]

We are excited to announce that VESPA is mature enough for its official 1.0 release! VESPA (VTK Enhanced with Surface Processing Algorithm) is a VTK module and a ParaView plugin dedicated to mesh and surface processing. VESPA brings the power of the CGAL (Computational Geometry Algorithms Library) library into VTK and ParaView workflows. By wrapping […]

3D Slicer is a multi-platform medical image informatics and visualization application, and a sizable fraction of its functionality lives in extensions. Many of those extensions are written in Python, and many of them depend on third-party Python packages: PyTorch for deep learning models, scikit-image for filtering, nnUNet for segmentation, and so on. How those dependencies […]

A Modern and Scalable Data Management Platform We are delighted to announce the release of Girder 5, a major rewrite that brings modern development practices, improved scalability, and a more maintainable codebase to our popular data management platform.  Girder has been the core infrastructure behind HistomicsTK and the Digital Slide Archive and is used with […]

ITK 5.4.6 is a maintenance release focused on performance improvements, security fixes, and platform compatibility.

The trame Python framework enables developers to create fast and reactive web applications. You may have seen that OpenFOAM can be configured interactively using trame, thanks to rich components in the trame ecosystem such as forms and VTK/ParaView 3D views. But what if you had multiple solvers that you want to configure, with a complex […]
