CMake 4.2 dropped the experimental gate on a major new feature: the CMake Instrumentation API. This enables detailed tracking of the entire CMake workflow, including configure time, build execution, testing, and installation, and provides developers and teams with actionable insights into build performance. Support for automated, user-written scripts to handle instrumentation data make it easy to track performance data over time across different machines and environments.

At CppCon 2026, I gave a talk called “CMake: Making Hard Things Easy” about how CMake handles build-system complexity so developers can focus on their software. This article shares practical takeaways from that talk. We started CMake for ITK 26 years ago. Researchers needed to use medical image segmentation and registration algorithms across different platforms without becoming experts in every compiler and linker. The idea was to capture that expertise in the build system so everyone could benefit from it. I wrote about those early days in Happy Birthday CMake!. Today, we take it for granted that we have build tools that can create static or shared libraries and link applications to them on Linux, Windows, or macOS.

PS: The examples in the blog requires VTK master, VTK nightly or VTK > 9.7. I keep coming back to this. Maybe because there is so much to uncover. We recently finished the third major rewrite of how VTK arrays can be processed in Python. I think that we got it right this time. I […]

ParaView 6.2.0 has been released! Notable additions to ParaView in this version highlighted in this post. For a comprehensive list of new features in ParaView 6.2.0, please see the ParaView 6.2.0 release notes hosted on ParaView’s GitLab project page. Performance optimizations for static meshes over time ParaView has been sped up significantly in some filters […]

This is a guest blog post from Ufuk Utku Turuncoglu from the NSF National Center for Atmospheric Research (NCAR). He shares his work on GeoGate, an open source component that brings ParaView Catalyst to Earth system models coupled through ESMF/NUOPC. Thanks to his approach of placing in situ analysis in the coupling layer that all […]

What’s New in VTK-wasm

September 17, 2026

Scientific and engineering visualization workflows have increasingly moved to the web. Developers are building applications with frameworks such as trame, Jupyter, and Panel that allow users to explore data directly in the browser while computationally intensive processing remains on the server. As these workflows continue to evolve, developers need efficient ways to deliver responsive 3D […]

Structural and diffusion MRI analysis often requires researchers to work across several specialized software packages. Each can have its own formats, conventions, APIs, and system-level dependencies. Building and maintaining these environments can become especially challenging when analysis needs to move between local workstations, institutional HPC clusters, and cloud environments. kwneuro has expanded to support a […]

It can be difficult to show visualization results during slide presentations, leading to a choice between videos or images, lacking in interactivity and detail, or pausing the presentation and switching to a running application, breaking the flow of the presentation. With trame and Reveal.js, you no longer have to choose between suboptimal choices. You can […]

Kitware is proud to recognize team members celebrating 5-, 10-, 15-, 20-, and 25-year milestones. As part of this year’s celebration, we unveiled a new recognition wall at our corporate headquarters honoring employees who have reached 25 years of service—the first individuals in Kitware’s history to achieve this milestone. While this installation commemorates a historic […]
