Question

我有兴趣设置一个用pyOpenGL编写粒子模拟器代码的环境。我已经安装了pyOpenGL。这是测试代码，只是为了确保opengl可以正常工作。

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


window = 0 
width, height = 500,400

def draw():
    glClear(GL_COLOR_BUFFER_BIT |GL_DEPTH_BUFFER_BIT)           
    glLoadIdentity()

glutDwapBuffers()                                           




#initialization
glutInit()
glutInitDisplayMode(GLUT_RGBA | GLUT_DOUBLE | GLUT_ALPHA | GLUT_DEPTH)
glutInitWindowSize(width,height)
glutInitWindowPosition(0,0)
window = glutCreateWindow(b"noobtute")
glutDisplayFunc(draw)                                                                       
glutIdleFunc(draw)  
glutMainLoop()

但是，当我从命令运行脚本时，我收到以下错误：

NameError: name 'glClear' is not defined
GLUT Display callback <function draw at 0x0000000002F8CB70> with (),{} failed: 
returning None name 'glClear' is not defined

我尝试重新安装pyOpengl但没有成功。

我在Windows 8.1上运行Python 3.4

如果您认为更多信息会有所帮助，请询问。感谢

更改

from OpenGL import *

到

from OpenGL.GL import *

但是，我赞成使用这种格式：

import OpenGL.GL as GL
import OpenGL.GLU as GLU
import OpenGL.GLUT as GLUT


window = 0 
width, height = 500,400

def draw():
    GL.glClear(GL.GL_COLOR_BUFFER_BIT |GL.GL_DEPTH_BUFFER_BIT)           
    GL.glLoadIdentity()
    GLUT.glutSwapBuffers()                                           




#initialization
GLUT.glutInit()
GLUT.glutInitDisplayMode(GLUT.GLUT_RGBA | GLUT.GLUT_DOUBLE | GLUT.GLUT_ALPHA |
GLUT.GLUT_DEPTH)
GLUT.glutInitWindowSize(width,height)
GLUT.glutInitWindowPosition(0,0)
window = GLUT.glutCreateWindow(b"noobtute")
GLUT.glutDisplayFunc(draw)                                                                       
GLUT.glutIdleFunc(draw)  
GLUT.glutMainLoop()

虽然不那么紧凑，但它可以帮助我保持正确的做法。

运行pyOpenGL时出现NameError
