Qt Quick 3D DynamicMeters demo

Image
Lately we have been working to perfect the Qt Quick 3D for the 5.15 release. There are still some tweaking to do, but things are looking pretty nice already!


In order to prove (to ourselves and to others) that Quick 3D is ready for the prime time, we have also been implementing some demos with it. Tomi already made a blog post about Quick 3D Benchmarking demo here, go check it out if you haven't already. This benchmarking application can be used to test many features of Quick 3D and to evaluate how different hardware can handle the load when the model count, complexity, texture sizes etc. are increased.

Another demo we have prepared is called DynamicMeters. The main targets of this demo were:
Demonstrate how Quick 3D and Qt Quick (2D) can easily be combined into single UX. While 3D is great, most applications want to combine also traditional 2D elements in different ways.Test how Quick 3D works together with 3rd party OpenGL libraries. Make sure that the performance is good and the…

Qt 5.10 QML Shape testing

Image
When implementing component into QtQuick UI which needs something more than rectangles, images and texts, pure declarative QML hasn't been enough. Popular choices to use for items with some sort of vector drawing are QML Canvas, QQuickPaintedItem or QNanoPainter.

But with Qt 5.10 there will be supports for new Shape element with paths that contain lines, quads, arcs etc. so I decided to install Qt 5.10 beta3 and implement all tests of "qnanopainter_vs_qpainter_demo" with also QML + Shape elements. (This kinda makes it "qnanopainter_vs_qpainter_vs_qmlshape_demo" but not renaming now). So here is in all glory the same UI implemented with QNanoPainter (left), QQuickPaintedItem (center), and QML+Shape (right):


Hard to spot the differences right? If only there would be a way to prove this, some way to x-ray into these UIs... like QSG_VISUALIZE=overdraw to visualize what Qt Quick Scene Graph Renderer sees?


Here you can see that scene graph sees QNanoPainter and QQuic…

Introducing QNanoPainter

Qt World Summit is just about to start! I’m not participating this time, but wanted to contribute one-more-thing to discuss in UI groups at the heart of Berlin ;)

During the past about six months we at QUIt Coding have had a side-side-project called QNanoPainter. This library is designed for implementing custom QQuickItems into Qt5 scene graph. Currently if you want to implement custom Qt Quick item, options are at least:

QQuickItem: Offers best performance due to Qt5 scene graph integration. But QSG* classes are relatively low-level with vertices, indices & materials. Painting more complicated things requires quite an expert and even then productivity is not very high.QQuickFramebufferObject: This is a good option if you want to draw with OpenGL into QQuickItem. But as we all know, OpenGL is also quite low-level API so no productivity wins here.QQuickPaintedItem: This means painting with good old QPainter C++ API. Weakness of QPainter with modern graphics accelerated hardware is t…
