Constructor & Destructor Documentation

MeshHierarchyManager()

MeshHierarchy::MeshHierarchyManager::MeshHierarchyManager	(	int	min_vertices = 1000,
		int	max_vertices = 10000
	)

Constructor.

Parameters

Member Function Documentation

generateHierarchyFromFile()

int MeshHierarchy::MeshHierarchyManager::generateHierarchyFromFile	(	const std::string &	input_mesh_file,
		const std::string &	output_dir,
		bool	fill_volume = true
	)

Generate hierarchy of meshes from input mesh file.

Parameters

input_mesh_file	Path to the input mesh file
output_dir	Directory to save the mesh hierarchy
fill_volume	Whether to fill volume with tetrahedra (true for 3D, false for 2D surface meshes)

Returns

Number of levels generated

Exceptions

std::runtime_error

if mesh loading or processing fails
