python,OpenGL加载obj模型

要在Python中加载和渲染OBJ模型，可以使用开源库PyOpenGL。下面是一个简单的加载和渲染OBJ模型的示例代码：

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

def load_obj(filename):
    vertices = []
    faces = []
    with open(filename) as f:
        for line in f:
            if line.startswith('v '):
                vertex = list(map(float, line.split()[1:]))
                vertices.append(vertex)
            elif line.startswith('f '):
                face = list(map(int, [i.split('/')[0] for i in line.split()[1:]]))
                faces.append(face)
    return vertices, faces

def draw_obj(vertices, faces):
    glBegin(GL_TRIANGLES)
    for face in faces:
        for vertex_id in face:
            glVertex3fv(vertices[vertex_id - 1])
    glEnd()

def main():
    pygame.init()
    display = (800, 600)
    pygame.display.set_mode(display, pygame.DOUBLEBUF | pygame.OPENGL)

    gluPerspective(45, (display[0] / display[1]), 0.1, 50.0)
    glTranslatef(0.0, 0.0, -5)

    vertices, faces = load_obj('your_obj_file.obj')

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

        glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT)
        draw_obj(vertices, faces)

        pygame.display.flip()
        pygame.time.wait(10)

if __name__ == '__main__':
    main()

这个示例代码使用了Pygame和PyOpenGL库，它加载了一个OBJ模型文件并在窗口中渲染出来。你可以根据自己的需求修改代码。
