**Creating a Customizable 3D Avatar Editor with Qt and PySide6** In this example, we will create a 3D avatar editor using Qt and PySide6. Our application will allow users to create and customize their own 3D avatars, with options to change the face shape, skin color, hair style, and clothing. **Prerequisites:** * Qt 6 or higher * PySide6 * 3D modeling software (such as Blender) for creating 3D assets * Basic knowledge of Qt and PySide6 **Step 1: Creating the 3D Assets** Before we start coding, we need to create the 3D assets for our editor. We will use Blender to create a simple 3D face model, skin, hair, and clothing. We will export these assets as OBJ files, which can be easily imported into our Qt application. **Step 2: Setting up the Qt Application** Create a new Qt project using PySide6 and add the following code to your main.py file: ```python import sys from PySide6.QtCore import Qt from PySide6.QtGui import QGuiApplication, QOpenGLContext from PySide6.QtWidgets import QApplication, QWidget from PySide6.Qt3DCore import Qt3DCore from PySide6.Qt3DExtras import Qt3DExtras class AvatarEditor(QWidget): def __init__(self): super().__init__() self.setWindowTitle("3D Avatar Editor") self.setGeometry(100, 100, 800, 600) self.scene = Qt3DCore.QEntity() self.camera = Qt3DExtras.QCamera(Qt3DCore.QCamera()) self.camera.setParent(self.scene) self.face = Qt3DExtras.QSphereMesh(Qt3DCore.QEntity()) self.skin = Qt3DExtras.QPhongMaterial(Qt3DCore.QEntity()) self.hair = Qt3DExtras.QPhongMaterial(Qt3DCore.QEntity()) self.clothing = Qt3DExtras.QPhongMaterial(Qt3DCore.QEntity()) self.scene.addComponent(self.face) self.scene.addComponent(self.skin) self.scene.addComponent(self.hair) self.scene.addComponent(self.clothing) self.view = Qt3DExtras.QOpenGLWidget(self.scene, self.camera) self.layout = QVBoxLayout() self.layout.addWidget(self.view) self.setLayout(self.layout) if __name__ == "__main__": app = QApplication(sys.argv) window = AvatarEditor() window.show() sys.exit(app.exec()) ``` This code creates a new Qt application with a 3D view and imports our 3D assets. **Step 3: Implementing the Avatar Editor** Next, we need to implement the avatar editor functionality. We will add UI elements to change the face shape, skin color, hair style, and clothing. We will also add a 3D preview window to display the edited avatar. ```python class AvatarEditor(QWidget): def __init__(self): super().__init__() # ... self.face_shape = QComboBox(self) self.face_shape.addItem("Male") self.face_shape.addItem("Female") self.face_shape.addItem("Neutral") self.skin_color = QComboBox(self) self.skin_color.addItem("White") self.skin_color.addItem("Black") self.skin_color.addItem("Asian") self.hair_style = QComboBox(self) self.hair_style.addItem("Short") self.hair_style.addItem("Long") self.hair_style.addItem("Bald") self.clothing_style = QComboBox(self) self.clothing_style.addItem("Casual") self.clothing_style.addItem("Formal") self.clothing_style.addItem("Uniform") self.layout.addWidget(self.face_shape) self.layout.addWidget(self.skin_color) self.layout.addWidget(self.hair_style) self.layout.addWidget(self.clothing_style) self.preview = Qt3DExtras.QOpenGLWidget(self.scene, self.camera) self.layout.addWidget(self.preview) self.face_shape.currentTextChanged.connect(self.change_face_shape) self.skin_color.currentTextChanged.connect(self.change_skin_color) self.hair_style.currentTextChanged.connect(self.change_hair_style) self.clothing_style.currentTextChanged.connect(self.change_clothing_style) def change_face_shape(self, text): if text == "Male": self.face.setShape(Qt3DExtras.QFace(Qt3DCore.QEntity())) elif text == "Female": self.face.setShape(Qt3DExtras.QFace(Qt3DCore.QEntity())) else: self.face.setShape(Qt3DExtras.QFace(Qt3DCore.QEntity())) def change_skin_color(self, text): if text == "White": self.skin.setColor(Qt3DCore.QColor(255, 255, 255)) elif text == "Black": self.skin.setColor(Qt3DCore.QColor(0, 0, 0)) else: self.skin.setColor(Qt3DCore.QColor(128, 128, 128)) def change_hair_style(self, text): if text == "Short": self.hair.setShape(Qt3DExtras.QHair(Qt3DCore.QEntity())) elif text == "Long": self.hair.setShape(Qt3DExtras.QHair(Qt3DCore.QEntity())) else: self.hair.setShape(Qt3DExtras.QHair(Qt3DCore.QEntity())) def change_clothing_style(self, text): if text == "Casual": self.clothing.setShape(Qt3DExtras.QClothing(Qt3DCore.QEntity())) elif text == "Formal": self.clothing.setShape(Qt3DExtras.QClothing(Qt3DCore.QEntity())) else: self.clothing.setShape(Qt3DExtras.QClothing(Qt3DCore.QEntity())) ``` This code adds UI elements to change the face shape, skin color, hair style, and clothing style. It also connects these UI elements to the change_face_shape, change_skin_color, change_hair_style, and change_clothing_style methods, which update the 3D avatar accordingly. **Conclusion:** In this tutorial, we created a 3D avatar editor using Qt and PySide6. Our application allows users to customize their 3D avatars by changing the face shape, skin color, hair style, and clothing style.
