在pyglet / opengl中渲染纹理立方体的最有效方法

如何解决在pyglet / opengl中渲染纹理立方体的最有效方法

目前，我有这段代码，用于渲染带纹理的立方体。它可以在几个多维数据集上正常工作，但是当我添加数百个多维数据集时，创建它会花费很多时间。

def get_tex(file):
    tex = pyglet.image.load(file).get_texture()
    glTexParameterf(GL_TEXTURE_2D,GL_TEXTURE_MIN_FILTER,GL_NEAREST)
    glTexParameterf(GL_TEXTURE_2D,GL_TEXTURE_MAG_FILTER,GL_NEAREST)
    return pyglet.graphics.TextureGroup(tex)


def make_textures(textures):
    result = {}
    base = "imgs/"
    faces = ("left","right","top","bottom","front","back")
    for face in faces:
        file_name = textures.get(face,textures.get("side"))
        result[face] = get_tex(base + file_name)
    return result

def get_vertices(x,y,z):
    dx,dy,dz = x + 1,y + 1,z + 1
    return [
        (x,z,x,dz,z),# side
        (dx,dx,dz),# side
        (x,# top
        (x,# bottom
        (dx,# side
    ]
class Grass:
    textures = make_textures({"side": "grass_side.png","top": "grass_top.png","bottom": "dirt.png"})


   
def draw_block(self,block):

    position = (block.x,block.y,block.z)
    if block._type == "grass":
        block = Grass
    else:
        block = Grass
    vertices = get_vertices(*position)
    faces = ("left","back")
    for vertex,face in zip(vertices,faces):
        self.batch.add(
            4,gl.GL_QUADS,block.textures[face],("v3f/static",vertex),("t2f/static",(0,1,1)),)

但这创建时间太长了，因为我正在调用gl函数，所以我不能使用其他线程来执行此操作。
