Detailed Description

VTriangle surface.

Surface mesh constructed of vertex triangles and vertices.

VTriangleSurface can be constructed triangle-by-triangle with internal elimination of duplicated vertices. Construction of of surface with external (more intelligent) vertex handling is also possible.

Constructor & Destructor Documentation

VTriangleSurface::VTriangleSurface

(

double

vertex_matching_eps = 1.0e-9

)

Constructor for vertex triangle surface.

The vertex matching tolerance can be set with vertex_matching_eps (defaults to 1.0e-9).

VTriangleSurface::~VTriangleSurface

(

)

Destructor.

Member Function Documentation

uint32_t VTriangleSurface::add_triangle	(	const Vec3D &	x1,
		const Vec3D &	x2,
		const Vec3D &	x3
	)

Add a triangle consiting of vertices x1, x2 and x3 with duplicate vertex elimination.

The vertices are assumed to be defined with right-hand ordering for defining outside direction. Each vertex of the triangle is checked against all vertices in the surface for duplicate entries. A vertex pairs closer than vertex_matching_eps are considered to be equal.

Returns the index of the new triangle.

uint32_t VTriangleSurface::add_triangle

(

const Vec3D

x[3]

)

Add a triangle consiting of vertices x with duplicate vertex elimination.

Convenience function.

uint32_t VTriangleSurface::add_triangle ( uint32_t  v1, uint32_t  v2, uint32_t  v3  )

inline

Add a triangle consiting of already defined vertices v1, v2 and v3.

uint32_t VTriangleSurface::add_triangle ( const uint32_t  v[3] )

inline

Add a triangle consiting of already defined vertices v.

Convenience function.

uint32_t VTriangleSurface::add_vertex

(

const Vec3D &

x

)

Add a vertex x with duplicate vertex elimination.

Returns the index of the (new or old) vertex.

uint32_t VTriangleSurface::add_vertex_no_check ( const Vec3D &  x )

inline

Add a vertex x without checking.

Returns the index of the new vertex.

void VTriangleSurface::clear

(

void

)

Clear surface.

void VTriangleSurface::debug_print

(

std::ostream &

os

)

const

Debug print.

void VTriangleSurface::set_vertex_matching_eps

(

double

vertex_matching_eps

)

Set vertex matching tolerance.

Defaults to 1.0e-9.

const VTriangle& VTriangleSurface::triangle ( uint32_t  i ) const

inline

Return triangle i.

uint32_t VTriangleSurface::trianglec ( void  ) const

inline

Return triangle count.

const Vec3D& VTriangleSurface::vertex ( uint32_t  i ) const

inline

Return vertex i coordinates.

uint32_t VTriangleSurface::vertexc ( void  ) const

inline

Return vertex count.
