MarchCube() [2/2]

Mesh MeshReconstruction::MarchCube	(	Fun3s const &	sdf,
		Rect3 const &	domain,
		Vec3 const &	cubeSize,
		double	isoLevel = 0,
		Fun3v	sdfGrad = nullptr )

Reconstructs a triangle mesh from a given signed distance function using Marching Cubes.

参数

sdf	The Signed Distance Function.
domain	Domain of reconstruction.
cubeSize	Size of marching cubes. Smaller cubes yields meshes of higher resolution.
isoLevel	Level set of the SDF for which triangulation should be done. Changing this value moves the reconstructed surface.
sdfGrad	Gradient of the SDF which yields the vertex normals of the reconstructed mesh. If none is provided a numerical approximation is used.

返回

The reconstructed mesh.
