I was reading a post from Hamlet Au over at New World notes regarding Mesh terrain, which you can read here. However what caught my attention most was a comment from Masami Kuramoto:
“What mesh brings to the terraforming table is the option to use subtractive modeling. Think caves, tunnels, subway stations, underground cities. It’s all possible now.”
I’m not quite sure what Masami means, but the idea of sims being to have cave tunnels, subway stations and underground cities is something that could really add a new dynamic to Second Life. Think of exploring deep mines or dungeons. People have long wanted to build underground in Second Life, the problem is, you can’t, you can’t build at a base level and then raise the terrain, that causes chaos, you get error messages or items returned to your lost and found.
