Possibility of partly removal of overlapped solid figure

[kmk111890]

I am looking for idea we can draw 3D figures partly removed by consideration of existence of obstacle, shade and so on. The ultimate purpose of this work is expressing camera coverage with cone figure like below picture. Unfortunately I didn't have any idea how to develop this work. You know, it is not simple placement of figures. I would like to automatically remove part behind obstacle in given space. Is there anybody can help me?
