Public Member Functions
size_t	countUniqueEdges () const
	Count the number of unique edges in the mesh by iterating through all triangles and adding their edges to an unordered_set.
float	calculateAspectRatio (const Triangle &t) const
	Calculate the aspect ratio of a triangle defined by its vertex indices. An aspect ratio near to 1 indicates a more equilateral triangle.
void	calculateAspectRatios ()
	Calculate the aspect ratio for all triangles in the mesh and store them in the ratios vector.
void	analyzeMesh ()
	Analyze the mesh by printing out the number of vertices, triangles, and unique edges. Optionally, it could also calculate and print the aspect ratio of each triangle for quality analysis.
bool	loadObj (const std::string &path)
	Load a mesh from an OBJ file using tinyobjloader.
std::unordered_map< Edge, int, EdgeHash >	getEdgeValences () const
	Get the Edge Valences object.
std::vector< Edge >	getBoundaryEdges () const
	Get the boundary edges of the mesh.
void	smooth (int iterations, float lambda)
	Smooth the mesh by iteratively moving each vertex towards the centroid of its neighbors.

Public Attributes
std::vector< Point >	vertices
	List of vertices in the mesh.
std::vector< Triangle >	triangles
	List of triangles defined by vertex indices.
std::vector< float >	ratios
	aspect ratios of triangles (for quality analysis)

const

Count the number of unique edges in the mesh by iterating through all triangles and adding their edges to an unordered_set.

Returns

number of unique edges in the mesh

getBoundaryEdges()

std::vector< Edge > Mesh::getBoundaryEdges

(

)

const

Get the boundary edges of the mesh.

Returns

A vector containing the boundary edges

getEdgeValences()

std::unordered_map< Edge, int, EdgeHash > Mesh::getEdgeValences

(

)

const

Get the Edge Valences object.

Returns

std::unordered_map<Edge, int, EdgeHash>

loadObj()

bool Mesh::loadObj

(

const std::string &

Load a mesh from an OBJ file using tinyobjloader.

Parameters

path	Path to the OBJ file to load

Returns

true

false

smooth()

void Mesh::smooth	(	int	iterations,
