VTK has recently introduced support for ONNX Runtime, opening new opportunities for integrating machine learning inferences into scientific visualization workflows. This feature is also available in ParaView through an official plugin. What are ONNX and ONNX Runtime? ONNX (Open Neural Network eXchange) is an open file format designed to represent machine learning models in a […]

High-performance simulations generate massive datasets—but extracting insight from that data shouldn’t be a bottleneck. ParaView Catalyst integrates analysis and visualization directly into the simulation workflow, delivering in situ processing that eliminates the need for slow, storage-heavy post-processing. The result? You get immediate feedback, streamlined workflows, and new opportunities to steer simulations on the fly. Built […]

Bug fixes made since ParaView 6.0.0 are listed below: Faulty default color map in ParaView 6.0.0 fixed The “Fast” color map, which is the new default in ParaView 6.0.0, was not correctly defined in the ParaView 6.0.0 release. Its color space was set to “Diverging” rather than “Lab”. As a result, the central lightest point […]

Deep learning currently dominates the field of medical image analysis. From brain tumor detection to cartilage segmentation and lung nodule analysis, convolutional and transformer-based neural networks often take center stage. Yet, behind every high-performing AI model, there is a need for reliable image preprocessing, spatial normalization, and data handling libraries. This is where the Insight […]

You can send build and test information to CDash even if you aren’t using CMake to build your software.  In this blog post, we’ll walk through the steps to set up CTest-driven testing that reports to a CDash dashboard. Following the example of the CMake tutorial where a C++ executable is created to calculate the […]

Are you a C++ developer looking to bring the Visualization Toolkit (VTK) to web applications? As many of you know, transforming a complex C++ library like VTK to compile with WebAssembly (WASM) is a tedious and time-consuming process. The good news is that we’ve made it easier so that you can use pre-built VTK.wasm libraries […]

This blog documents a major change introduced in ParaView 6.0.0. It also applies to VTK 9.5.0 The ParaView command-line executables pvserver, pvpython and pvbatch now support all three modes of rendering – headless, offscreen, and onscreen in one build. The rendering backend is automatically selected at runtime based upon the system capabilities such as availability of an X server or […]

Python state files in ParaView are a way to create reproducible and editable visualization pipelines. Especially for applications like Catalyst, these state files are intended to be readable, modifiable, and adaptable to different workflows.

We are excited to showcase a collaboration between Openwater and Kitware Inc. to accelerate the development and adoption of Low-Intensity Focused Ultrasound (LIFU) technology. Combining Openwater’s cutting-edge hardware with Kitware’s expertise in medical software development, we aim to make LIFU accessible to researchers and medical device developers through the OpenLIFU hardware and software suite. Openwater’s […]

Introduction There is increasing demand for powerful, interactive data visualizations directly within web browsers. VTK.wasm is a technology that aims to provide this capability by delivering complex visualization applications without requiring traditional software installations. Not only are these applications portable, but they provide performance at near-native speeds.  In this post, we describe some recent steps […]

CppCon is the premier annual C++ conference, uniting developers from around the world to learn, collaborate, and shape the future of C++. At Kitware, our connection to the C++ community runs deep—our co-founder and Chief Technical Officer, Bill Hoffman, is the original architect of CMake, which has become an essential build system for C++ projects across the globe.

We are pleased to announce the official releases of ParaView 6.0 and the Visualization Toolkit (VTK) 9.5. This occasion marks a strategic evolution in our release methodology, as we are synchronizing the release schedules of ParaView and VTK for the first time. This alignment is designed to deliver significant advantages to our user and developer […]

Many scientific and engineering applications are still built as standalone desktop tools. While these solutions may have served teams well in the past, they often present modern-day challenges: they’re difficult to share, hard to maintain, and disconnected from today’s collaborative and distributed workflows.

For a comprehensive list of new features in ParaView 6.0.0, please see the ParaView 6.0.0 release notes hosted on ParaView’s GitLab project page. A selection of notable new features is described on this page. A new default background and color map The default background has changed from “Blue Gray Background” to “Warm Gray Background”. The […]

We previously introduced VolView Insight, a powerful extension of the VolView medical visualization platform, that is designed to integrate imaging studies with real-world clinical data. Built for interoperability and flexibility, Volview Insight allows clinicians and researchers to view medical images, run multimodal AI pipelines, and access relevant patient records, all within a modern and intuitive web […]
