3d动态圣诞树代码编程python

在Python中编写一个简单的3D动态圣诞树代码可以利用matplotlib库的3D绘图功能。这里是一个基本的例子，使用了Pygame模块来创建动画效果，因为matplotlib本身并不支持3D动画：

import pygame
from OpenGL.GL import *
from OpenGL.GLU import *

# 定义颜色
GREEN = (0, 255, 0)
WHITE = (255, 255, 255)

class Tree(pygame.sprite.Sprite):
    def __init__(self, size=100):
        super().__init__()
        self.size = size
        self.vertices = [
            # 树干部分
            (-size, -size, 0), (size, -size, 0), (0, size, 0),
            (-size, -size, 0), (0, size, 0), (size, -size, 0),

            # 分支部分
            (-size, -size*1.5, size), (size, -size*1.5, size), (0, size*1.5, size),
            (-size, -size*1.5, size), (0, size*1.5, size), (size, -size*1.5, size),
        ]
        self.indices = [(i, i+1, i+2) for i in range(0, len(self.vertices), 3)]

    def draw(self, screen):
        glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT)
        glEnable(GL_DEPTH_TEST)

        glBegin(GL_TRIANGLES)
        glColor3ub(*WHITE)
        for v1, v2, v3 in self.indices:
            glVertex3f(*self.vertices[v1])
            glVertex3f(*self.vertices[v2])
            glVertex3f(*self.vertices[v3])
        glEnd()

        pygame.display.flip()

pygame.init()
tree = Tree()
screen = pygame.display.set_mode((800, 600), pygame.DOUBLEBUF | pygame.OPENGL)
clock = pygame.time.Clock()

while True:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            quit()

    tree.draw(screen)
    clock.tick(30)  # 设置帧率
