panda3d有一个长方形的最小点和最大点请写一个函数计算这个长方形的8个顶点坐标

假设长方形的最小点为(min_x, min_y, min_z)，最大点为(max_x, max_y, max_z)，则长方形的8个顶点坐标可以计算如下：

1. (min_x, min_y, min_z)
2. (max_x, min_y, min_z)
3. (max_x, max_y, min_z)
4. (min_x, max_y, min_z)
5. (min_x, min_y, max_z)
6. (max_x, min_y, max_z)
7. (max_x, max_y, max_z)
8. (min_x, max_y, max_z)

以下是Python代码实现：

def calculate_vertices(min_x, min_y, min_z, max_x, max_y, max_z):
    vertices = []
    vertices.append((min_x, min_y, min_z))
    vertices.append((max_x, min_y, min_z))
    vertices.append((max_x, max_y, min_z))
    vertices.append((min_x, max_y, min_z))
    vertices.append((min_x, min_y, max_z))
    vertices.append((max_x, min_y, max_z))
    vertices.append((max_x, max_y, max_z))
    vertices.append((min_x, max_y, max_z))
    return vertices
