能否提供具体的代码，在Python里用pyopengl圆滑3D模型的棱角

在Python中使用PyOpenGL创建圆滑3D模型并减少棱角通常涉及到网格生成、平滑处理以及着色器的应用。这里是一个基本示例，展示了如何通过TriangulationMesh模块从原始立方体数据转换到更平滑的表面：

import numpy as np
from OpenGL.GL import *
from pyrr import Matrix44, Vector3

# 创建一个立方体的数据
vertices = [(x, y, z) for x in [-1, 1] for y in [-1, 1] for z in [-1, 1]]
faces = [
    (0, 1, 2), (2, 3, 0),
    (4, 5, 6), (6, 7, 4),
    (8, 9, 10), (10, 11, 8),
    (12, 13, 14), (14, 15, 12),
    (0, 4, 8), (8, 12, 0),
    (1, 5, 9), (9, 13, 1),
    (2, 6, 10), (10, 14, 2),
    (3, 7, 11), (11, 15, 3)
]

# 将顶点数据转换成光滑的网格
def smooth_faces(faces):
    result = []
    for face in faces:
        new_face = [face[0], face[1]]
        result.append(new_face)

        edge1 = Vector3(vertices[face[1]] - vertices[face[0]])
        edge2 = Vector3(vertices[face[2]] - vertices[face[0]])

        # 计算新顶点
        center = (vertices[face[0]] + vertices[face[1]]) * 0.5 + (vertices[face[2]] + vertices[face[0]]) * 0.5
        normal = edge1.cross(edge2).normalize()
        result.append((center.x, center.y, center.z))

        result.extend([(center.x+normal.x, center.y+normal.y, center.z+normal.z), (center.x-normal.x, center.y-normal.y, center.z-normal.z)])
    return result

smooth_vertices = smooth_faces(faces)

# 初始化PyOpenGL
glEnable(GL_DEPTH_TEST)
glEnableClientState(GL_VERTEX_ARRAY)
glVertexPointer(3, GL_FLOAT, 0, np.array(smooth_vertices, dtype=np.float32).tobytes())

# 设置其他所需的设置，如纹理坐标等...

请注意，这个示例仅提供了一个基本的概念，并未包含完整的渲染循环和光照设置，实际应用可能需要结合现代三维图形库如GLFW或PyGame来构建完整的应用程序。
