函数
bool	eve::procgen::generateHexPlanetMesh (const Params &params, MeshBuild &out, std::string &error)
	Build the dual of a subdivided icosahedron. The result is a closed planet made of hexagonal cells plus the twelve pentagons required by spherical topology. Params: radius (1), subdivisions (2), tileInset (0.06, in [0, 0.5)).

bool	eve::procgen::marchingCubes (const float density, int nx, int ny, int nz, float isolevel, MeshBuild &out, std::string error=nullptr)
	Classic Marching Cubes (Lorensen & Cline) over a regular scalar volume. Density >= isolevel is treated as solid; normals point toward empty space.

bool	eve::procgen::fillDensityField (const Params &params, std::vector< float > &density, int &nx, int &ny, int &nz, std::string &error)
	Fill a density volume from a named field recipe (sphere / noise / terrain / torus).

bool	eve::procgen::generateMarchingCubesMesh (const Params &params, MeshBuild &out, std::string &error)
	Build mesh from Params (field + resolution + isolevel).
