如何将相机绑定到modelVisual3d对象(房间内)内 [英] How to bound camera inside a modelVisual3d object(inside a room)

问题描述

你好，

我创建了一个由3ds Max的天花板和地板的墙壁组成的房间，并通过测试了modelvisual3d对象来查找单击了哪个模型，但是我很难将相机限制在房间内.

我正在旋转，并根据需要移动相机的外观方向，但无法绑定相机.

请帮忙.

推荐答案

我找到了解决方案，
解决方案不是很好，但是我只能想到这种解决方案.

我计算了ModelVisual3D并得到了GeometryModel3D.bound，这给了我Rect3D.
现在，我比较了Rect3D.contains(相机位置)，它满足了我的需求.

当然，在旋转时，您需要更新相机的位置，这是另一部分.如果有人得到更好的解决方案，请告诉我. :)

I found the solution,
the solution is not as good, but i could think of only this solution.

I calculated the ModelVisual3D and got the GeometryModel3D.bound which gave me Rect3D.
Now i compared the Rect3D.contains(camera position) which gave me what i needed.

Ofcourse while rotating u need to update the position of the camera, which is another part.If anyone get a better solution, let me know. :)
