Up until now, we've only worked with basic materials. To create a convincing 3D scene, proper materials and more advanced lighting is needed. Qt Quick 3D supports a number of techniques to achieve this, and in this section we will look at a few of them.到目前

When working with 3D scenes, the built in meshes quickly grow old. Instead, a good flow from a modelling tool into QML is needed. Qt Quick 3D comes with the Balsam asset import tool, which is used to convert common asset formats into a Qt Quick 3D friendly

Wednesday July 13, 2022 by Ulf Hermann | Comments​2022年7月13日星期三，乌尔夫·赫尔曼评论This is the eighth installment in the series of blog posts on how to adjust your QML application to take the maximum advantage of qmlsc. In the first post we've set up the environment

Qt Quick 3D offers a rich way of integrating 3D contents into a Qt Quick scene, allowing a tight integration through QML.Qt Quick 3D提供了一种将3D内容集成到Qt Quick场景的丰富方法，允许通过QML进行紧密集成。When working with 3D contents, the most common approach is to work with assets cr

Qt Quick 3D has been built to integrate nicely into the traditional Qt Quick used to build dynamic 2D contents.Qt Quick 3D已经构建，可以很好地集成到用于构建动态2D内容的传统Qt Quick中。It is straight forward to mix 3D contents into a 2D scene, as the element represents a 2D surface

In this section we will walk through the basics of Qt Quick 3D. This includes working with the built in shapes (meshes), using lights, and transformations in 3D.在本节中，我们将介绍Qt Quick 3D的基础知识。这包括使用内置形状（网格）、使用灯光和三维变换。A 3D scene consists of a few standard elemen

The Qt Quick 3D module takes the power of QML to the third dimension. Using Qt Quick 3D you can create three dimensional scenes and use the property bindings, state management, animations, and more from QML to make the scene interactive. You can even mix 2

Summary小结In this chapter we've scratched the surface of Qt for MCUs and Qt Quick Ultralite. These technologies brings Qt to much smaller platforms and make it truly embeddable. Through-out this chapter, we've used the virtual desktop target, which allo

Working with Models使用模型In Qt Quick Ultralite, it is possible to create models in QML using theListModelelement. It is also possible, and a bit more interesting, to create models from C++. This lets you expose lists of data from C++ to QML and to inst..

Integrating with C++与C++的集成The C++In order to demonstrate the connection between C++ and QML in Qt for MCUs, we will create a simpleCountersingleton holding an integer value. Notice that we start from astructand not aclass. This is common practi...

Hello World - for MCUsAs the setup of Qt for MCU can be a bit tricky, we will start with aHello Worldlike example to ensure that the toolchain works, and so that we can discuss the basic differences between Qt Quick Ultralite and standard Qt Quick.由于..

Setup设置Qt for MCUscomes with support for a range of evaluation boards from companies such as NCP, Renesas, ST, and Infinion/Cypress. These are good for getting started and helps you try out the integration to the specific MCU. In the end, you will mos.

Qt for MCUsNotice注意Qt for MCUs is not a part of the open source Qt distribution, but as a commercial add-on.Qt for MCU不是开源Qt发行版的一部分，而是一个商业附加组件。Qt for MCUs is a Qt version takes Qt for platforms that are too small to run Linux. Instead, Qt for M

Summary小结In this chapter we're had a look at what the Qt Quick Shapes module has to offer. Using it we can create arbitrary shapes directly in QML, and leverage the property binding system of QML to create dynamic shapes. We've also had a look at the v

Animating Shapes为形状设置动画One of the nice aspects of using Qt Quick Shapes, is that the paths drawn are defined directly in QML. This means that their properties can be bound, transitioned and animated, just like any other property in QML.使用Qt Quick Sha

Filling Shapes填充形状A shape can be filled in a number of different ways. In this section we will have a look at the general filling rule, and also the various ways a path can be filled.形状可以用多种不同的方式填充。在本节中，我们将了解一般填充规则，以及填充路径的各种方式。Qt Quick Shapes provi

Building Paths构建路径As we saw in the last section, shapes are built from paths, which are built from path elements. The most common way to build a path is to close it, i.e. to ensure that it starts and ends in the same point. However, it is possible to c

A Basic Shape基本形状The shape module lets you create arbitrarily paths and then stroke the outline and fill the interior. The definition of the path can be reused in other places where paths are used, e.g. for thePathViewelement used with models. But to..

Quick Starter快速入门This chapter provides an overview of QML, the declarative user interface language used in Qt 6. We will discuss the QML syntax, which is a tree of elements, followed by an overview of the most important basic elements. Later we will br

Summary小结In this chapter we have looked at the PySide6 module from the Qt for Python project. After a brief look at installation, we focused on how Qt concepts are used from Python. This included slots, signals and properties. We also looked at a basic

Limitations局限性At the moment, there are some things that are not easily available. One of them is that you cannot easily create QML plugins using Python. Instead you need to import the Python QML “modules” into your Python program and then use qmlRegist

Building an Application构建应用程序In this chapter we will look at how you can combine Python and QML. The most natural way to combine the two worlds is to do as with C++ and QML, i.e. implement the logic in Python and the presentation in QML.在本章中，我们将介绍如何将
