python 3d方块咋做

Question

问题遇到的现象和发生背景 :
最近我想做3d，发现了pyglet。但，我不会用pyglet。

我想要达到的结果:
出现一个屏幕，里面有一个草方块，跟MC的差不多。

图片资源：
草方块顶面图片路径：H:/mc/grass.png
草方块侧面图片路径：H:/mc/grass_soil.png
草方块底面图片路径：H:/mc/soil.png

Answer 1

import pyglet
from pyglet.gl import *

# ----------------------------------------------
# 1. 资源路径（改成你自己的）
# ----------------------------------------------
TOP_IMG   = r'H:/mc/grass.png'      # 草顶
SIDE_IMG  = r'H:/mc/grass_soil.png' # 草+泥侧面
BOTTOM_IMG= r'H:/mc/soil.png'       # 纯泥土底面

# ----------------------------------------------
# 2. 把 pyglet.image 转成 OpenGL texture
# ----------------------------------------------
def load_texture(path):
    img = pyglet.image.load(path)
    texture = img.get_texture()
    glBindTexture(GL_TEXTURE_2D, texture.id)
    # 纹理参数：最近邻过滤 + 重复边缘
    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST)
    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_NEAREST)
    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_CLAMP_TO_EDGE)
    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_CLAMP_TO_EDGE)
    return texture

# ----------------------------------------------
# 3. 建一个立方体：6 面 → 12 三角形 → 36 顶点
#    每顶点：position(3) + texcoord(2)
# ----------------------------------------------
def make_cube_vertices(size=1.0):
    s = size/2
    # 顶点坐标
    vertices = (
        # 前面 (+Y)
        -s,-s, s,  0,0,   s,-s, s,  1,0,   s, s, s,  1,1,  -s, s, s,  0,1,
        # 后面 (-Y)
         s,-s,-s,  0,0,  -s,-s,-s,  1,0,  -s, s,-s,  1,1,   s, s,-s,  0,1,
        # 右面 (+X)
         s,-s, s,  0,0,   s,-s,-s,  1,0,   s, s,-s,  1,1,   s, s, s,  0,1,
        # 左面 (-X)
        -s,-s,-s,  0,0,  -s,-s, s,  1,0,  -s, s, s,  1,1,  -s, s,-s,  0,1,
        # 顶面 (+Z)
        -s, s, s,  0,0,   s, s, s,  1,0,   s, s,-s,  1,1,  -s, s,-s,  0,1,
        # 底面 (-Z)
        -s,-s,-s,  0,0,   s,-s,-s,  1,0,   s,-s, s,  1,1,  -s,-s, s,  0,1,
    )
    return (GLfloat * len(vertices))(*vertices)

# 4. 初始化 OpenGL
# ----------------------------------------------
def setup():
    glEnable(GL_DEPTH_TEST)
    glEnable(GL_TEXTURE_2D)
    glEnable(GL_CULL_FACE)
    glClearColor(0.5, 0.7, 1.0, 1)  # 天蓝色背景

# ----------------------------------------------
# 5. 窗口事件
# ----------------------------------------------

    def __init__(self):

        self.rot_x = -20

        glRotatef(self.rot_x, 1, 0, 0)
        glRotatef(self.rot_y, 0, 1, 0)

        # 画 6 个面
        glInterleavedArrays(GL_T2F_V3F, 0, self.vertices)
        # 0 前 1 后 2 右 3 左 4 顶 5 底
        for face in range(6):
            if face == 4:   # 顶
                glBindTexture(GL_TEXTURE_2D, self.tex_top.id)
            elif face == 5: # 底
                glBindTexture(GL_TEXTURE_2D, self.tex_bottom.id)
            else:           # 四周
                glBindTexture(GL_TEXTURE_2D, self.tex_side.id)
            glDrawArrays(GL_QUADS, face*4, 4)

    def on_mouse_drag(self, x, y, dx, dy, buttons, modifiers):
        if buttons & pyglet.window.mouse.LEFT:
            self.rot_y += dx*0.5
            self.rot_x += dy*0.5

# 6. 运行

if __name__ == '__main__':
    Win()
    pyglet.app.run()
