pyqt openglwidget如何导入obj模型

您可以使用PyOpenGL库中的gluNewQuadric()函数来导入obj模型。首先，您需要安装PyOpenGL库，然后使用以下代码导入obj模型：

from OpenGL.GL import *
from OpenGL.GLU import *
from OpenGL.GLUT import *

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

def draw_obj(filename):
vertices, normals, faces = load_obj(filename)
glBegin(GL_TRIANGLES)
for face in faces:
for vertex in face:
glVertex3fv(vertices[vertex[0] - 1])
glNormal3fv(normals[vertex[2] - 1])
glEnd()

然后，您可以使用以下代码将obj模型导入到OpenGL窗口中：

class MyGLWidget(QGLWidget):
def initializeGL(self):
glClearColor(0.0, 0.0, 0.0, 0.0)
glEnable(GL_DEPTH_TEST)

def paintGL(self):
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT)
glLoadIdentity()
glTranslatef(0.0, 0.0, -5.0)
glColor3f(1.0, 1.0, 1.0)
draw_obj('model.obj')

def resizeGL(self, width, height):
glViewport(0, 0, width, height)
glMatrixMode(GL_PROJECTION)
glLoadIdentity()
gluPerspective(45.0, float(width) / float(height), 0.1, 100.0)
glMatrixMode(GL_MODELVIEW)

widget = MyGLWidget()
widget.show()

请注意，这只是一个简单的示例，您可能需要根据您的具体需求进行更改。
