Combine 2D and 3D elements in UI design with Qt Quick
summary
Qt Quick 3D provides a unified 2D/3D scene graph and QML API, uses the command‑line asset tool Balsam to convert OBJ/FBX/blender/gltf into optimized QML models, and integrates into Qt Design Studio 1.4 so designers can drag‑drop conditioned assets. It offers node transforms, cameras (perspective/ortho/frustum/custom), lights, PBR principal material plus custom shaders, and off‑screen or direct rendering; available as a tech preview targeting Qt 5.14 with OpenGL ES2/3 and GL3+ backends, working but still adding procedural geometry, post processing, and input/collision optimizations.
