linux 把文件test.tar.gz改名为backup.tar.gz

您可以使用PyOpenGL库中的glu模块中的函数来导入obj模型。具体来说，您可以使用gluNewQuadric()函数创建一个新的四面体对象，然后使用gluQuadricDrawStyle()函数设置绘制样式，最后使用gluSphere()函数绘制球体。您还可以使用gluDeleteQuadric()函数删除四面体对象。以下是示例代码：

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

def load_obj(filename):
    vertices = []
    normals = []
    texcoords = []
    faces = []
    for line in open(filename, "r"):
        if line.startswith('#'): continue
        values = line.split()
        if not values: continue
        if values[0] == 'v':
            vertices.append(map(float, values[1:4]))
        elif values[0] == 'vn':
            normals.append(map(float, values[1:4]))
        elif values[0] == 'vt':
            texcoords.append(map(float, values[1:3]))
        elif values[0] == 'f':
            face = []
            texcoords = []
            norms = []
            for v in values[1:]:
                w = v.split('/')
                face.append(int(w[0]))
                if len(w) >= 2 and len(w[1]) > 0:
                    texcoords.append(int(w[1]))
                else:
                    texcoords.append(0)
                if len(w) >= 3 and len(w[2]) > 0:
                    norms.append(int(w[2]))
                else:
                    norms.append(0)
            faces.append((face, norms, texcoords))
    return vertices, normals, texcoords, faces

def draw_obj(vertices, normals, texcoords, faces):
    glBegin(GL_TRIANGLES)
    for face in faces:
        face_vertices, face_normals, face_texcoords = face
        for i in range(3):
            if normals:
                glNormal3fv(normals[face_normals[i] - 1])
            if texcoords:
                glTexCoord2fv(texcoords[face_texcoords[i] - 1])
            glVertex3fv(vertices[face_vertices[i] - 1])
    glEnd()

def main():
    pygame.init()
    display = (800, 600)
    pygame.display.set_mode(display, DOUBLEBUF | OPENGL)
    gluPerspective(45, (display[0] / display[1]), 0.1, 50.0)
    glTranslatef(0.0, 0.0, -5)
    obj_vertices, obj_normals, obj_texcoords, obj_faces = load_obj("model.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(obj_vertices, obj_normals, obj_texcoords, obj_faces)
        pygame.display.flip()
        pygame.time.wait(10)

if __name__ == '__main__':
    main()

希望这可以帮助您！
