Suppose we have two convex bodies in 3D space. Let’s call them $B_1$ and $B_2$. Let’s denote their projection curves on the xy plane by: $P_{1xy}$ and $P_{2xy}$, on the yz plane by: $P_{1yz}$ and $P_{2yz}$, on the zx plane by: $P_{1zx}$ and $P_{2zx}$.
Suppose the following three conditions are met:
- $P_{2xy}$ lies completely inside $P_{1xy}$.
- $P_{2yz}$ lies completely inside $P_{1yz}$.
- $P_{2zx}$ lies completely inside $P_{1zx}$.
Are these conditions sufficient to say that B2 lies completely inside B1?
Thank you!
