Detailed Description

template<class T, class P, class BV, size_t K>
class FastSmoothUnionIF< T, P, BV, K >

Implicit function smoothed union using BVHs.

Note

If the BVH-enabled union is to make sense, the primitives must be distance fields (I think). There's a static_assert to make sure of that.
