我想要编写一个程序，能够交互地创建一组矩形并进行2D变换的代码

以下是一个示例程序，可以交互地创建矩形并进行平移、旋转和缩放变换：

import pygame
import math

# 初始化pygame
pygame.init()

# 设置窗口尺寸和标题
size = (800, 600)
screen = pygame.display.set_mode(size)
pygame.display.set_caption("Interactive Rectangles Transform")

# 定义颜色
BLACK = (0, 0, 0)
WHITE = (255, 255, 255)
RED = (255, 0, 0)

# 定义矩形类
class Rectangle:
    def __init__(self, pos, size):
        self.pos = pos
        self.size = size
        self.angle = 0
        self.scale = 1

    def draw(self, surface):
        # 计算矩形的四个顶点坐标
        vertices = [
            (self.pos[0] - self.size[0] / 2, self.pos[1] - self.size[1] / 2),
            (self.pos[0] + self.size[0] / 2, self.pos[1] - self.size[1] / 2),
            (self.pos[0] + self.size[0] / 2, self.pos[1] + self.size[1] / 2),
            (self.pos[0] - self.size[0] / 2, self.pos[1] + self.size[1] / 2)
        ]
        # 将四个顶点坐标按照当前角度和缩放比例进行变换
        vertices = [self._rotate_and_scale_vertex(v) for v in vertices]
        # 绘制矩形
        pygame.draw.polygon(surface, RED, vertices)

    def translate(self, dx, dy):
        # 平移矩形
        self.pos = (self.pos[0] + dx, self.pos[1] + dy)

    def rotate(self, angle):
        # 旋转矩形
        self.angle += angle

    def scale_up(self):
        # 放大矩形
        self.scale *= 1.1

    def scale_down(self):
        # 缩小矩形
        self.scale /= 1.1

    def _rotate_and_scale_vertex(self, vertex):
        # 将一个顶点进行旋转和缩放变换
        dx = vertex[0] - self.pos[0]
        dy = vertex[1] - self.pos[1]
        r = math.sqrt(dx**2 + dy**2)
        theta = math.atan2(dy, dx) + math.radians(self.angle)
        x = self.pos[0] + r * math.cos(theta) * self.scale
        y = self.pos[1] + r * math.sin(theta) * self.scale
        return (x, y)

# 创建一个矩形列表
rectangles = []

# 运行主循环
done = False
while not done:
    # 处理事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            done = True
        elif event.type == pygame.MOUSEBUTTONDOWN:
            # 创建一个新矩形并添加到列表中
            pos = pygame.mouse.get_pos()
            size = (50, 50)
            rectangles.append(Rectangle(pos, size))
        elif event.type == pygame.KEYDOWN:
            # 对所有矩形进行变换
            if event.key == pygame.K_UP:
                for rectangle in rectangles:
                    rectangle.translate(0, -10)
            elif event.key == pygame.K_DOWN:
                for rectangle in rectangles:
                    rectangle.translate(0, 10)
            elif event.key == pygame.K_LEFT:
                for rectangle in rectangles:
                    rectangle.translate(-10, 0)
            elif event.key == pygame.K_RIGHT:
                for rectangle in rectangles:
                    rectangle.translate(10, 0)
            elif event.key == pygame.K_r:
                for rectangle in rectangles:
                    rectangle.rotate(10)
            elif event.key == pygame.K_s:
                for rectangle in rectangles:
                    rectangle.scale_up()
            elif event.key == pygame.K_a:
                for rectangle in rectangles:
                    rectangle.scale_down()

    # 绘制背景和所有矩形
    screen.fill(WHITE)
    for rectangle in rectangles:
        rectangle.draw(screen)

    # 更新屏幕
    pygame.display.update()

# 退出pygame
pygame.quit()
