No idea how long that takes but there was some code floating round our forums at one point.

Yeah, I did think about the possibility of a bunch of Box Colliders, but I wonder if that would be viable for voxel volumes where there was likely to be frequent alterations made to the voxel data? Looking great though, can't wait to play with it =) Ah nice, quad merging too!

The boxes are all Unity Box Colliders and the terrain is a Mesh Collider with something like 12,000 triangles as I recall. You can see a wire frame here: https://pbs.twimg.com/media/BIusZM5CYAANrMW.png:orig Eventually we should replace the Mesh Collider with a set of Box Colliders to approximate the shape, but that's just an optimisation really.

We intend to sell Cubiquity as a plugin which links PolyVox to Unity3D, and so it's all in a private repository. Thanks Joe, but actually the source code isn’t public.

I've got a voxel-based game idea that I was planning on making in Unity soon. I've rolled my own voxel mesh generation in Unity before, but I'm sure polyvox would do this better than I ever could achieve on my own. I will watch this space =) Awesome!

When it's in a better state I'll get your opinion on it since your C# is definitely better than mine :) Well it’s already kinda working.

I found it worked very well and able to wrap PolyVox quite easily. The main problem I found was that since it's basically compiling the LLVM IR to EMCAScript you have to deal with all the C++ ABI name-mangling issues so none of the functions have pleasant names. My next step would have been to generate a simple C API over PolyVox and then wrap that with emscripten but I didn't get around to it. A future version of SWIG is hopefully going to support generating a C API maybe that's an option. Regardless, I'd love to see what you manage to get working so be sure to post about it on the forums.
