Public Member Functions
	Vertex ()
	Construct a new Vertex object with members declared not initialized.

	Vertex (const int index, const double x, const double y, const double z)
	Constructs a new Vertex object with x,y,z coordinates.

	Vertex (const int index, const Matrix &coord)
	Constructs a new Vertex object with Matrix of size (3,1)

void	update_coord_with_prev_coord ()
	Update the current vertex coordinate with the previous coordinate by copying the values of the previous coordinate matrix to the current coordinate.

void	approximate_unit_normal_vector (std::vector< Face > &faces)
	Approximate the normal vector of the current vertex by averaging the normal vector of all surrounding faces. The output will be store in member variable normVector.

	force exerted on the vertex

Force	forcePrev
	force exerted on the vertex from the previous iteration

bool	isGhost = false
	“Ghost vertices” are defined as points on the boundary of the triangular mesh that only serve to provide reference when calculating limit surface on the boundary, as calculating position of a point on the limit surface require the coordinates of 12 neighboring vertices (if regular). However, the “ghost vertices” themselves do not correspond to real points on the surface.

◆ isGhost

bool Vertex::isGhost = false

“Ghost vertices” are defined as points on the boundary of the triangular mesh that only serve to provide reference when calculating limit surface on the boundary, as calculating position of a point on the limit surface require the coordinates of 12 neighboring vertices (if regular). However, the “ghost vertices” themselves do not correspond to real points on the surface.

◆ layerIndex

int Vertex::layerIndex = 0

used in multi-layer (a.k.a. leaflet) model; 0 for middle layer; +1 for upper layer

◆ normVector

Matrix Vertex::normVector

normal vector to the corresponding point on limit surface

◆ reflectiveVertexIndex

int Vertex::reflectiveVertexIndex = -1

reflective vertex used in periodic boundary condition

◆ type

VertexType Vertex::type = VertexType::Real

used in boundary condition
