Qt 6.11 is out as the latest version of this cross-platform toolkit used by the KDE desktop and widely by both open-source and closed-source applications.
Qt 6.11 introduces Qt Canvas Painter as a new means of 2D graphics drawing built atop the Qt Rendering Hardware Interface for hardware acceleration of 2D UIs. The new Qt Canvas Painter should be much faster than the existing QPainter with OpenGL back-end. Qt Canvas Painter was inspired in part by HTML5’s canvas 2D context.
On the 3D side, Qt 6.11 is promoted as having “the same 3D capabilities as a game engine”:
“Improvements to One of the Best 3D Frameworks
Qt has evolved into offering the same 3D capabilities as a game engine but providing consistent, high performance. That means UIs with Qt Quick 3D run smoothly even with complex elements, effects, or animations.”
Qt 6.11 adds Screen Space Global Illumination (SSGI), Screen Space Reflections (SSR), and motion vectors. There is also advanced render-pass customization support with Qt 6.11’s 3D capabilities.
Qt 6.11 also brings new graphs, Qt TaskTree as a technology preview for a new declarative means of asynchronous coding, improved Lottie and SVG animation support, easier QML and C++ integration, and other changes.
