Detailed Description

template<class MeshT>
class OpenMesh::Decimater::ModProgMeshT< MeshT >

Collect progressive mesh information while decimating.

The progressive mesh data is stored in an internal structure, which can be evaluated after the decimation process and (!) before calling the garbage collection of the decimated mesh.

◆ postprocess_collapse()

template<class MeshT>
void OpenMesh::Decimater::ModProgMeshT< MeshT >::postprocess_collapse ( const CollapseInfo _ci)
inlineoverridevirtual

Stores collapse information in a queue.

infolist()

Reimplemented from OpenMesh::Decimater::ModBaseT< MeshT >.

Definition at line 133 of file ModProgMeshT.hh.

◆ write()

template<class MeshT >
bool OpenMesh::Decimater::ModProgMeshT< MeshT >::write ( const std::string &  _ofname)

Write progressive mesh data to a file in proprietary binary format .pm.

The methods uses the collected data to write a progressive mesh file. It's a binary format with little endian byte ordering:

  • The first 8 bytes contain the word "ProgMesh".
  • 32-bit int for the number of vertices NV in the base mesh.
  • 32-bit int for the number of faces in the base mesh.
  • 32-bit int for the number of halfedge collapses (now vertex splits)
  • Positions of vertices of the base mesh (32-bit float triplets).
    [x,y,z][x,y,z]...
  • Triplets of indices (32-bit int) for each triangle (index in the list of vertices of the base mesh defined by the positions.
    [v0,v1,v2][v0,v1,v2]...
  • For each collapse/split a detail information package made of 3 32-bit floats for the positions of vertex v0, and 3 32-bit int indices for v1, vl, and vr. The index for vl or vr might be -1, if the face on this side of the edge does not exists.
Remarks
Write file before calling the garbage collection of the mesh.
Parameters
_ofnameName of the file, where to write the progressive mesh
Returns
true on success of the operation, else false.
