panda3d通过长方体对角线两个坐标点:xyz的最大值和最小值判断一个点是否在这个长方体范围内完整代码
以下是一个使用Panda3D的Python代码示例,可以通过长方体对角线的最大值和最小值来判断一个点是否在长方体范围内:
from panda3d.core import Point3, BoundingBox
# 创建一个长方体,其中min_xyz和max_xyz是对角线两个坐标点的最小值和最大值
box = BoundingBox(Point3(min_xyz), Point3(max_xyz))
# 创建一个点,判断它是否在长方体范围内
point = Point3(x, y, z)
if box.contains(point):
print("Point is inside the box!")
else:
print("Point is outside the box.")
完整代码示例:
from direct.showbase.ShowBase import ShowBase
from panda3d.core import Point3, BoundingBox
from direct.task import Task
class MyApp(ShowBase):
def __init__(self):
ShowBase.__init__(self)
# 创建一个长方体,其中min_xyz和max_xyz是对角线两个坐标点的最小值和最大值
box = BoundingBox(Point3(-1, -1, -1), Point3(1, 1, 1))
# 创建一个点,判断它是否在长方体范围内
point = Point3(0, 0, 0)
if box.contains(point):
print("Point is inside the box!")
else:
print("Point is outside the box.")
# 创建一个任务循环,以便我们可以检查点是否在长方体内
self.taskMgr.add(self.checkPointTask, "checkPointTask", extraArgs=[box, point])
def checkPointTask(self, box, point, task):
# 模拟点的移动
point.setX(point.getX() + 0.01)
# 检查点是否在长方体内
if box.contains(point):
print("Point is inside the box!")
else:
print("Point is outside the box.")
return Task.cont
app = MyApp()
app.run()
