panda3d获取一个模型1glb的长方体边框的8个坐标点按这个格式保存下来vertices = Point3-1 -1 0 Point31 -1 0 Point31 1 0 Point3-1 1 0 Point3-1 -1 1 Point31 -1 1 Point31 1 1 Point3-1 1 1完整代码

以下是获取模型1.glb长方体边框8个坐标点的完整代码：

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/1.glb")
        model.reparentTo(self.render)
        
        # 获取模型边界框
        bounds = model.getBounds()
        min_point, max_point = bounds.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)
        
app = MyApp()
app.run()

在代码中，我们首先加载了模型1.glb，并获取了它的边界框。然后，通过边界框的最小和最大点，计算了长方体边框的8个顶点坐标。最后，将这些坐标点打印出来
