virtual bool ACG::SceneGraph::ACG::MeshCompilerFaceInput::getFaceAttr ( const int  _faceID,
const int  _attrID,
int *  _out 
) const
inlinevirtual

Get an index buffer of a face for a specific attribute channel.

Parameters
_faceIDface index
_attrIDattribute channel
_outpointer to output buffer, use getFaceSize(_faceID) to get the size needed to store face data
Returns
true if successful, false otherwise

Reimplemented in ACG::SceneGraph::ACG::MeshCompilerDefaultFaceInput.

virtual int* ACG::SceneGraph::ACG::MeshCompilerFaceInput::getFaceAttr ( const int  _faceID,
const int  _attrID 
) const
inlinevirtual

Get an index buffer of a face for a specific attribute channel.

Parameters
_faceIDface index
_attrIDattribute channel
Returns
array data of size "getFaceSize(_faceID)", allowed to return 0 when array data not permanently available in memory

virtual int ACG::SceneGraph::ACG::MeshCompilerFaceInput::getFaceSize ( const int  _faceID) const
pure virtual

Get number of vertices per face.

Parameters
_faceIDface index

Implemented in ACG::SceneGraph::ACG::MeshCompilerDefaultFaceInput.

virtual int ACG::SceneGraph::ACG::MeshCompilerFaceInput::getNumIndices ( ) const
pure virtual

Get total number of indices in one attribute channel.

i.e. total number of position indices of the whole mesh

Implemented in ACG::SceneGraph::ACG::MeshCompilerDefaultFaceInput.

virtual int ACG::SceneGraph::ACG::MeshCompilerFaceInput::getSingleFaceAttr ( const int  _faceID,
const int  _faceCorner,
const int  _attrID 
) const
virtual

Get a single vertex-index entry of a face.

Parameters
_faceIDface index
_faceCornervertex corner of the face
_attrIDattribute channel
Returns
index-data if successful, -1 otherwise

Reimplemented in ACG::SceneGraph::ACG::MeshCompilerDefaultFaceInput.

virtual int ACG::SceneGraph::ACG::MeshCompilerFaceInput::getVertexAdjCount ( const int  _vertexID) const
inlinevirtual

Get the number of adjacent faces for a vertex.

Parameters
_vertexIDvertex index
Returns
number of adjacent faces, return -1 if adjacency information unavailable

Definition at line 188 of file MeshNode2T.cc.

virtual int ACG::SceneGraph::ACG::MeshCompilerFaceInput::getVertexAdjFace ( const int  _vertexID,
const int  _k 
) const
inlinevirtual

Get the index of an adjacent face for a vertex.

Parameters
_vertexIDvertex index
_kadjacency list entry in range [0, .., adjCount - 1]
Returns
face id of adjacent face, return -1 if adjacency information is available
