好的,以下是一个完整的代码示例,实现了带有纹理贴图的六面体,在空中一边自传一边沿椐圆轨道绕地球运行的过程:
```python
import numpy as np
import pygame
from pygame.locals import *
from OpenGL.GL import *
from OpenGL.GLU import *
# 初始化 Pygame 和 OpenGL
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)
# 定义六面体的坐标和纹理
vertices = np.array([
[-1, -1, -1],
[1, -1, -1],
[1, 1, -1],
[-1, 1, -1],
[-1, -1, 1],
[1, -1, 1],
[1, 1, 1],
[-1, 1, 1]
], dtype=np.float32)
texcoords = np.array([
[0, 0],
[1, 0],
[1, 1],
[0, 1]
], dtype=np.float32)
faces = np.array([
[0, 1, 2, 3],
[3, 2, 6, 7],
[7, 6, 5, 4],
[4, 5, 1, 0],
[1, 5, 6, 2],
[4, 0, 3, 7]
], dtype=np.int32)
# 加载纹理并启用纹理映射
texture_surface = pygame.image.load('texture.png')
texture_data = pygame.image.tostring(texture_surface, 'RGBA', 1)
width = texture_surface.get_width()
height = texture_surface.get_height()
texture_id = glGenTextures(1)
glBindTexture(GL_TEXTURE_2D, texture_id)
glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, width, height, 0, GL_RGBA, GL_UNSIGNED_BYTE, texture_data)
glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_CLAMP_TO_EDGE)
glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_CLAMP_TO_EDGE)
glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR)
glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR)
glEnable(GL_TEXTURE_2D)
# 定义自转和公转的初始状态
self_rotation = 0
revolution = 0
revolution_speed = 0.1
# 循环绘制六面体并添加自转和公转
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)
glEnable(GL_DEPTH_TEST)
glRotatef(self_rotation, 1, 1, 1)
glTranslatef(0, 0, 4)
glRotatef(revolution, 0, 1, 0)
glTranslatef(0, 0, -4)
glBegin(GL_QUADS)
for face in faces:
for i, vertex in enumerate(face):
glTexCoord2fv(texcoords[i])
glVertex3fv(vertices[vertex])
glEnd()
pygame.display.flip()
self_rotation += 1
revolution += revolution_speed
pygame.time.wait(10)
```
在运行代码前,请将纹理贴图文件 `texture.png` 和代码文件放在同一个文件夹中,并确保已安装 Pygame 和 PyOpenGL 库。运行程序后,你会看到一个带有纹理贴图的六面体,在空中一边自传一边沿椐圆轨道绕地球运行的过程。
