PySide6 pygragh绘制可旋转的三维坐标轴

要在 PySide6 中使用 pygraph 绘制可旋转的三维坐标轴，可以按照以下步骤进行：

1. 安装 pygraph：使用 pip 命令安装 pygraph，命令如下：

pip install pygraph

2. 导入必要的库：在 Python 代码中导入必要的库，包括 PySide6 和 pygraph。代码如下：

from PySide6.QtCore import Qt
from PySide6.QtGui import QVector3D
from PySide6.QtWidgets import QApplication, QMainWindow, QGraphicsScene, QGraphicsView
from pygraph import Axis, Graph3D, Grid3D, RotationHandler, ZoomHandler

3. 创建图形场景和视图：创建一个 QGraphicsScene 对象和 QGraphicsView 对象来显示 pygraph 绘制的图形。代码如下：

class MainWindow(QMainWindow):
    def __init__(self):
        super().__init__()

        # 创建图形场景和视图
        self.scene = QGraphicsScene()
        self.view = QGraphicsView(self.scene)
        self.view.setRenderHint(QPainter.Antialiasing)
        self.view.setViewportUpdateMode(QGraphicsView.FullViewportUpdate)
        self.view.setOptimizationFlag(QGraphicsView.DontAdjustForAntialiasing, True)
        self.view.setOptimizationFlag(QGraphicsView.DontSavePainterState, True)

        self.setCentralWidget(self.view)

4. 创建 3D 坐标轴和网格：使用 pygraph 中的 Axis 和 Grid3D 类来创建 3D 坐标轴和网格。代码如下：

class MainWindow(QMainWindow):
    def __init__(self):
        super().__init__()

        # 创建图形场景和视图
        self.scene = QGraphicsScene()
        self.view = QGraphicsView(self.scene)
        self.view.setRenderHint(QPainter.Antialiasing)
        self.view.setViewportUpdateMode(QGraphicsView.FullViewportUpdate)
        self.view.setOptimizationFlag(QGraphicsView.DontAdjustForAntialiasing, True)
        self.view.setOptimizationFlag(QGraphicsView.DontSavePainterState, True)

        self.setCentralWidget(self.view)

        # 创建 3D 坐标轴和网格
        self.axis = Axis(self.scene, length=10, width=0.2, divisions=10, center=QVector3D(0, 0, 0))
        self.grid = Grid3D(self.scene, length=10, width=0.2, divisions=10, center=QVector3D(0, 0, 0))

5. 添加旋转和缩放功能：使用 pygraph 中的 RotationHandler 和 ZoomHandler 类来添加旋转和缩放功能。代码如下：

class MainWindow(QMainWindow):
    def __init__(self):
        super().__init__()

        # 创建图形场景和视图
        self.scene = QGraphicsScene()
        self.view = QGraphicsView(self.scene)
        self.view.setRenderHint(QPainter.Antialiasing)
        self.view.setViewportUpdateMode(QGraphicsView.FullViewportUpdate)
        self.view.setOptimizationFlag(QGraphicsView.DontAdjustForAntialiasing, True)
        self.view.setOptimizationFlag(QGraphicsView.DontSavePainterState, True)

        self.setCentralWidget(self.view)

        # 创建 3D 坐标轴和网格
        self.axis = Axis(self.scene, length=10, width=0.2, divisions=10, center=QVector3D(0, 0, 0))
        self.grid = Grid3D(self.scene, length=10, width=0.2, divisions=10, center=QVector3D(0, 0, 0))

        # 添加旋转和缩放功能
        self.rotation_handler = RotationHandler(self.view)
        self.zoom_handler = ZoomHandler(self.view)

6. 显示图形：在主程序中显示图形。代码如下：

if __name__ == '__main__':
    app = QApplication([])
    window = MainWindow()
    window.show()
    app.exec()

这样，就可以在 PySide6 中使用 pygraph 绘制可旋转的三维坐标轴了。
