If all goes well Qt 6.0 will make its official debut in December. One of the areas much talked about for Qt 6 development has been the graphics architecture changes and better supporting more APIs besides OpenGL.

Qt developer Laszlo Agocs has written a blog post outlining some of the fundamental graphics changes that have made the cut for Qt 6.0:

- The Qt Rendering Hardware Interface (QRhi) is much more polished and with faster performance compared to the early state it shipped in with Qt 5.15.

- Shaders are now written in Vulkan-style GLSL rather than OpenGL-compatible GLSL snippets.

- The Direct OpenGL code-path without going through the Qt Rendering Hardware Interface has been removed. In other words, no path to go straight from Qt Quick to OpenGL.

- Various OpenGL-specifics were removed from the API.

- The Qt Company has updated their demos and scene-graph examples to reflect the API changes relevant to application developers.

- Qt on Windows is no longer shipping with ANGLE for offering better OpenGL support, since native Direct3D 11 support and the like is available.
