Explore the evolution of 3D graphics handling in Qt 6 through this conference talk that examines the framework's transition from OpenGL dependency to a multi-API approach. Learn about Qt's major architectural changes that enable rendering Qt Quick and Qt Quick 3D scenes across Vulkan, Metal, Direct 3D 11/12, and OpenGL through new abstraction layers. Discover how Qt 6 addresses the challenges of cross-platform graphics development by implementing open-source libraries for shader translation, moving away from the single 3D API limitations of Qt 5. Understand the real-world implications of maintaining Qt's compatibility promises while supporting diverse platforms and devices, including exotic hardware configurations. Gain insights into the technical challenges, compromises, and both positive and negative aspects encountered during this significant framework transformation, presented through practical examples from the development journey of modernizing a large-scale 2D/3D application framework.
