Qt/3D QML Scripting for UI Designers and Hackers
summary
Shows practical Qt/3D QML bindings that let QML load and animate real 3D assets using a C++ backend: a 3DS loader, scene graph with view frustum culling, shared geometry so many penguins (≈5,000 triangles each) run on an SGX GPU, while one very dense mesh causes OOM on N900. Uses Qt Creator, QML animations, qglShaderProgram and shader profiles (high/med/low) for cross‑platform shaders, simple color‑buffer picking, and a model viewer plugin; demos run at native GPU speed and mostly work despite some live‑demo flakiness.
