Detailed Description

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

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.

[inline]

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:

_ofname

Name of the file, where to write the progressive mesh

Returns:

true on success of the operation, else false.
