Constructor & Destructor Documentation

◆ CTriangleMesh() [1/5]

CTriangleMesh::CTriangleMesh ( )

Standart constructor creates an empty mesh.

Referenced by clone(), clone_connectivity(), CTriangleMesh(), and ~CTriangleMesh().

◆ CTriangleMesh() [2/5]

CTriangleMesh::CTriangleMesh ( const CTriangleMesh & orig )

copy constructor makes a shallow copy of the mesh, i.e. the storage for triangles, vertices, normals, textur-coordinates, colors and the deformation-scale is shared between original and copy

Parameters

orig	the mesh to be copied

References CTriangleMesh().

◆ CTriangleMesh() [3/5]

CTriangleMesh::CTriangleMesh	(	int	n_triangles,
		int	n_vertices )

contruct an mesh with uninitialized data

Parameters

n_triangles	number of triangles
n_vertices	number of vertices

◆ CTriangleMesh() [4/5]

CTriangleMesh::CTriangleMesh	(	PTrianglefield	triangles,
		PVertexfield	vertices,
		PNormalfield	normals,
		PColorfield	colors,
		PScalefield	scales )

creates a new mesh from given input data

Parameters

triangles	the triangle data (required)
vertices	the vertex data (required)
normals	per vertex normals - can be NULL, in this case then the normals are calculated
colors	per vertex color
scales

◆ CTriangleMesh() [5/5]

CTriangleMesh::CTriangleMesh	(	PTrianglefield	triangles,
		PVertexfield	vertices )

creates a new mesh from given input data

Parameters

triangles	the triangle data (required)
vertices	the vertex data (required)

◆ ~CTriangleMesh()

CTriangleMesh::~CTriangleMesh ( )

Destructor - it releases all the data.

References CTriangleMesh().

Member Function Documentation

◆ clone()

CTriangleMesh * CTriangleMesh::clone ( ) const

Returns: a copy of this mesh

References CTriangleMesh().

◆ clone_connectivity()

CTriangleMesh CTriangleMesh::clone_connectivity ( ) const

Returns: a mesh where the connectivity is copied, the vertices are allocated, but not set, and without normals and scale values

References clone_connectivity(), and CTriangleMesh().

Referenced by clone_connectivity().

◆ color_at()

const color_type & CTriangleMesh::color_at ( unsigned int i ) const

Returns: the color at the given index i

Parameters

i

References color_at().

Referenced by color_at().

◆ evaluate_normals()

void CTriangleMesh::evaluate_normals ( )

Force the re-evaluation of the normals of the mesh. The normal at a vertex is evaluared as the area-weighted average of the normals of the triangles, the vertex is part of.
