Detailed Description

A generic mesh with index-based vertex access.

Implements the GenericMesh interface.

Member Function Documentation

_getTriangle()

virtual GenericTriangle * CCCoreLib::GenericIndexedMesh::_getTriangle ( unsigned  triangleIndex )

pure virtual

Returns the ith triangle.

Virtual method to request a triangle with a specific index. The returned object can be temporary.

Parameters

triangleIndex

of the requested triangle (between 0 and the mesh size-1)

Returns

the requested triangle, or 0 if index value is not valid

Implemented in CCCoreLib::Delaunay2dMesh, and CCCoreLib::SimpleMesh.

getNextTriangleVertIndexes()

virtual VerticesIndexes * CCCoreLib::GenericIndexedMesh::getNextTriangleVertIndexes ( )

pure virtual

Returns the indexes of the vertices of the next triangle (relatively to the global iterator position)

Returns

the triangle indexes (or 0 if the global iterator is out of bounds)

Implemented in CCCoreLib::Delaunay2dMesh, and CCCoreLib::SimpleMesh.

getTriangleVertices()

virtual void CCCoreLib::GenericIndexedMesh::getTriangleVertices ( unsigned  triangleIndex, CCVector3 &  A, CCVector3 &  B, CCVector3 &  C  ) const

pure virtual

Returns the vertices of a given triangle.

Parameters

[in]	triangleIndex	index of the triangle (between 0 and the size(mesh)-1)
[out]	A	first vertex
[out]	B	second vertex
[out]	C	third vertex

Implemented in CCCoreLib::Delaunay2dMesh, and CCCoreLib::SimpleMesh.

getTriangleVertIndexes()

virtual VerticesIndexes * CCCoreLib::GenericIndexedMesh::getTriangleVertIndexes ( unsigned  triangleIndex )

pure virtual

Returns the indexes of the vertices of a given triangle.

Parameters

triangleIndex

index of the triangle (between 0 and size(mesh)-1)

Returns

the triangle indexes (or 0 if index value is not valid)

Implemented in CCCoreLib::Delaunay2dMesh, and CCCoreLib::SimpleMesh.

interpolateNormals()

virtual bool CCCoreLib::GenericIndexedMesh::interpolateNormals ( unsigned  triIndex, const CCVector3 &  P, CCVector3 &  N  )

inlinevirtual

Interpolates normal(s) inside a given triangle.

This method should be ideally overriden by the child class if normals are supported

Parameters

[in]	triIndex	triangle index
[in]	P	point where to interpolate (should be inside the triangle!)
[out]	N	interpolated normal

Returns

success

Reimplemented in CCCoreLib::SimpleMesh.

normalsAvailable()

virtual bool CCCoreLib::GenericIndexedMesh::normalsAvailable ( ) const

inlinevirtual

Returns whether normals are available.

Reimplemented in CCCoreLib::SimpleMesh.
