The error is caused by using the getTightBounds() method on a BoundingSphere object, which does not have this method. To fix this, you can use the getBounds() method instead, which returns a BoundingBox object that does have the getTightBounds() method. Here's the updated code:

from panda3d.core import Point3 from panda3d.core import NodePath from direct.showbase.ShowBase import ShowBase from direct.actor.Actor import Actor

class MyApp(ShowBase): def init(self): ShowBase.init(self)

    # 加载模型1.glb
    model = self.loader.loadModel("models/box")
    model.reparentTo(self.render)
    
    # 获取模型边界框
    bounds = model.getBounds()
    bbox = bounds.asBox()
    min_point, max_point = bbox.getTightBounds()
    
    # 计算边框8个顶点坐标
    vertices = [
        Point3(min_point[0], min_point[1], min_point[2]),
        Point3(max_point[0], min_point[1], min_point[2]),
        Point3(max_point[0], max_point[1], min_point[2]),
        Point3(min_point[0], max_point[1], min_point[2]),
        Point3(min_point[0], min_point[1], max_point[2]),
        Point3(max_point[0], min_point[1], max_point[2]),
        Point3(max_point[0], max_point[1], max_point[2]),
        Point3(min_point[0], max_point[1], max_point[2]),
    ]
    print(vertices)
