void	append (const Vec &v)
	append a property (e.g., color, texture coordinates) to this vertex.

Public Attributes
int	index

Detailed Description

A vertex carries both xyz coordinates and its attributes (e.g., color, texcoord).

Constructor & Destructor Documentation

Vertex() [1/4]

Vertex ( const vec3 & xyz, int idx = 0 )

inlineexplicit

initialize with xyz coordinates and an optional index.

Parameters

idx	The index of this vertex. Providing a non-negative index allows to map a resulting vertex to the original vertex. Any new vertex generated in the tessellation will have a negative index -1.

Vertex() [2/4]

template<typename FT>

Vertex ( const FT * data, std::size_t size, int idx = 0 )

inline

initialize from a C-style array.

Parameters

idx	The index of this vertex. Providing a non-negative index allows to map a resulting vertex to the original vertex. Any new vertex generated in the tessellation will have a negative index -1.

Attention

The first 3 components must be the xyz coordinates.

Vertex() [3/4]

Vertex ( std::size_t size = 0, int idx = 0 )

inlineexplicit

initialize with a known size but memory is allocated without data initialization.

Parameters

idx	The index of this vertex. Providing a non-negative index allows to map a resulting vertex to the original vertex. Any new vertex generated in the tessellation will have a negative index -1.

Vertex() [4/4]

Vertex ( const Vertex & v, int idx = 0 )

inline

copy constructor.

Parameters

idx	The index of this vertex. Providing a non-negative index allows to map a resulting vertex to the original vertex. Any new vertex generated in the tessellation will have a negative index -1.

Member Function Documentation

append()

template<typename Vec>

void append ( const Vec & v )

inline

append a property (e.g., color, texture coordinates) to this vertex.

Template Parameters

Vec	The vector type of the vertex property, e.g., vec2, vec3.

Parameters

v	The value of the vertex property.

Note

The order you retrieve the properties must be the same as they were appended.
