我正在尝试使用Python及其包pygame、numpy、PyOpenGL和PyOpenGL_accelerate绘制一个3D立方体。当我按下箭头按钮时,3D立方体也会向其他方向旋转。例如,当我按下右箭头时,它会向右旋转。
首先,我在其他电脑上试过,它运行得很好。但后来,我也在我的笔记本电脑上试过,当我运行它时,它在屏幕上没有显示任何东西。我成功地安装了所需的软件包和所有,但它仍然没有显示任何东西。
下面是我的代码:
import pygame
from pygame.locals import *
from OpenGL.GL import *
from OpenGL.GLU import *
pygame.init()
display = (800, 600)
pygame.display.set_mode(display, DOUBLEBUF|OPENGL)
pygame.display.set_caption("03 lab 1 ")
gluPerspective(45, (display[0]/display[1]), 0.1, 50.0)
glTranslatef(0, 0, -5)
angle = 1
rotatex = 0
rotatey = 0
rotatez = 0
def draw_cube():
glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT)
glBegin(GL_LINES)
glVertex3f(-0.5, 0.5, 0)
glVertex3f(-0.5, -0.5, 0)
glVertex3f(-0.5, -0.5, 0)
glVertex3f(0.5, -0.5, 0)
glVertex3f(0.5, -0.5, 0)
glVertex3f(0.5, 0.5, 0)
glVertex3f(0.5, 0.5, 0)
glVertex3f(-0.5, 0.5, 0)
glVertex3f(-0.5, 0.5, 1)
glVertex3f(-0.5, -0.5, 1)
glVertex3f(-0.5, -0.5, 1)
glVertex3f(0.5, -0.5, 1)
glVertex3f(0.5, -0.5, 1)
glVertex3f(0.5, 0.5, 1)
glVertex3f(0.5, 0.5, 1)
glVertex3f(-0.5, 0.5, 1)
glVertex3f(-0.5, 0.5, 0)
glVertex3f(-0.5, 0.5, 1)
glVertex3f(0.5, 0.5, 0)
glVertex3f(0.5, 0.5, 1)
glVertex3f(-0.5, -0.5, 0)
glVertex3f(-0.5, -0.5, 1)
glVertex3f(0.5, -0.5, 0)
glVertex3f(0.5, -0.5, 1)
glEnd()
while True:
for event in pygame.event.get():
if event.type == pygame.KEYDOWN:
if event.key == pygame.K_LEFT:
rotatey -= 1
if event.key == pygame.K_RIGHT:
rotatex += 1
if event.key == pygame.K_UP:
rotatey += 1
if event.key == pygame.K_DOWN:
rotatex -= 1
if event.type == pygame.QUIT:
pygame.quit()
quit()
glRotate(angle, rotatex, rotatey,rotatez)
pygame.display.flip()
pygame.time.wait(15)
draw_cube()
这是我的输出结果。它只是显示一个空白屏幕。

绘制立方体后必须更新显示,在
glEnd()
后调用pygame.display.flip()
,需要在每一帧中重新绘制立方体,并更改每一帧中的旋转矩阵,这是Indentation的问题,应用程序循环的缩进错误。
