Embedding Next-Gen Graphics: VTK’s Hardware Windows, WebGPU, and QVTKWebGPUWidgetFor most of VTK’s history, rendering and window management went hand in hand. A single vtkRenderWindow handled it all: creating the OS window, managing the OpenGL context, running the event loop, and drawing pixels. In the early days of OpenGL, pairing them together made perfect sense—the graphics context was tightly bound to the window, so […]📝Kitware Inc

Qt Bridges Technology Preview: Qt Quick UIs for Rust and C# DevelopersWhen we announced Qt Bridges at Qt World Summit 2025, we had a simple goal: let developers build Qt Quick user interfaces with a backend written in their favorite programming languages. This year, the C# and Rust bridges went through several public betas. Thank you to everyone who tried them and sent feedback. It shaped every release.📝Qt Blog

Introducing NetMaestro: Open Source Network Modeling and SimulationNetwork engineers need to evaluate changes to infrastructure without disrupting the systems that depend on it. Testing a new configuration, replacing equipment, or investigating a potential failure can be difficult when physical testbeds are expensive and production networks cannot be used for experimentation. Kitware is developing NetMaestro, an open source network modeling and simulation tool that allows engineers to investigate congestion, compare configurations, and explore what-if scenarios using virtual network models before making changes to production infrastructure.📝Kitware Inc
Billion-query-per-second lookup tables in C++A lot of software spends its time mapping strings to values. A web server must identify the HTTP method (GET, POST, …). It must recognize header names. A URL parser must recognize the protocol (http, https, ftp, …). A compiler must recognize keywords. In C++, the default approach is to put the strings in a … Continue reading Billion-query-per-second lookup tables in C++📝Daniel Lemire's blog

With Qt 6.12, the SkyMaterial is the limitQt Quick 3D 6.12 introduces a new SkyMaterial QML type, and in this post we will explain what it is, how to use it and why you'd want to. SkyMaterial provides a way of writing custom fragment shader code to render a scene's sky, as well as computing image-based lighting (IBL) from it. This means the same sky acts as both the visible background and a light source for the scene. With it you can create a dynamic sky with a moving sun, day/night cycle, clouds, stars etc. QML properties set on the SkyMaterial type are automatically made available in the custom shader, and whenever a property is updated, the SkyMaterial re-renders itself. This is what makes it possible to have a dynamic sky. Since the rendering is happening on the GPU, the performance cost depends on the complexity of the shader and how often it is updated. It is possible to tweak certain quality and performance properties to fit your performance budget. To use SkyMaterial in your 3D scene you need to point the SceneEnvironment::skyMaterial property to your SkyMaterial object, and set SceneEnvironment::backgroundMode to SceneEnvironment.SkyMaterial .📝Qt Blog

The C++26 inplace_vector containerThe C++26 standard features a new container called std::inplace_vector, that sits in between the std::array and std::vector containers. It’s a container with a compiled-time fix capacity – like std::array, but a runtime variable size – like std::vector. In this article, we will discuss how it works and when to use it. A tale of two ... Read more The post The C++26 inplace_vector container first appeared on Marius Bancila's Blog .📝Marius Bancila's Blog

Bazel releases addressing the eMudhra CA compromiseThe Bazel team has published new releases of Bazel and Bazelisk to address the recent disclosure of the eMudhra intermediate CA private key compromise . The following Bazel releases remove the distrusted eMudhra and Sectigo AAA root CA certificates from the bundled JDK: 7.7.2 8.8.2 9.3.1 10.0.0rc2 If you cannot immediately upgrade to one of the patched releases above (or are using an older, unsupported Bazel release), you can work around the issue by passing --host_jvm_args=-Djavax.net.ssl.trustStore= to point Bazel's JVM at an updated trust store that excludes the distrusted roots. We have also released Bazelisk v1.30.0 , built with Go 1.27.3 to address CVE-2026-111943 . Thanks to community member James Sharpe for bringing this issue to our attention.📝Bazel BlogThursday, October 22, 2026
