【中文标题】Pyopengl 给我价值错误无法识别问题【英文标题】:Pyopengl giving me Value error not able to identify the problem 【发布时间】:2020-09-29 11:53:53 【问题描述】:我开始在 python 中使用 opengl,我的代码与 youtuber 的代码完全相同,但它给了我一个错误:
pygame 1.9.6 Hello from the pygame community. https://www.pygame.org/contribute.html Traceback (most recent call last):
File "C:/python files/Opengl/Opengl_cheatsheet.py", line 66, in <module>

ValueError: ('Expected 12 byte array, got 8 byte array', (-1, 0), None)
这是我的代码:
import pygame
from pygame.locals import *
from OpenGL.GL import *
from OpenGL.GLU import *
#vertices for the cube tuples
vertices = ((1, -1, -1),
(1, 1, -1),
(-1, 1 -1),
(-1, -1, -1),
(1, -1, 1),
(1, 1, 1),
(-1, -1, 1),
(-1, 1, 1),
)
#edge for the cube tuples
edges = ((0,1),
(0,3),
(0,4),
(2,1),
(2,3),
(2,7),
(6,3),
(6,4),
(6,7),
(5,1),
(5,4),
(5,7),
)
def cube():
glBegin(GL_LINES)
for edge in edges:
for vertex in edge:
glVertex3fv(vertices[vertex])
glEnd()
def main():
pygame.init()
display = (800, 800)
pygame.display.set_mode(display, DOUBLEBUF|OPENGL)
gluPerspective(45, (display[0]/display[1]), 0.1, 50.0)
glTranslatef(0.0, 0.0, -5)
glRotatef(0, 0, 0, 0)
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)
cube()
pygame.display.flip()
pygame.time.wait(10)
main()
【问题讨论】:
这是一个错字。vertices
中缺少 ,
。 (第三个顶点)
ohhhhh,真是个愚蠢的错误!!!!
傻不傻,谢谢!我把括号排成一长串,导致我来到这里。
很好,它帮助了你@Joshua Clayton
【参考方案1】:
这是一个错字。顶点列表中缺少,
。 (第三个顶点):
vertices = ((1, -1, -1), (1, 1, -1), (-1, 1 -1), # <------- (-1, -1, -1), (1, -1, 1), (1, 1, 1), (-1, -1, 1), (-1, 1, 1), )
