C++ (Cpp) MeshGroup::childrenEnd示例

示例#1

void
countVertices(MeshGroup const & mg, long & num_vertices)
{
  for (MeshGroup::MeshConstIterator mi = mg.meshesBegin(); mi != mg.meshesEnd(); ++mi)
    num_vertices += (*mi)->numVertices();

  for (MeshGroup::GroupConstIterator ci = mg.childrenBegin(); ci != mg.childrenEnd(); ++ci)
    countVertices(**ci, num_vertices);
}

示例#2

// A rather hacky way of forming a joint descriptor, suitable only for exact matches like we want here
void
accumGroupFeatures(MeshGroup const & mg, TheaArray<double> & features)
{
  for (MeshGroup::MeshConstIterator mi = mg.meshesBegin(); mi != mg.meshesEnd(); ++mi)
  {
    TheaArray<double> const & mf = (*mi)->getFeatures();
    if (features.empty())
      features.resize(mf.size());

    alwaysAssertM(mf.size() == features.size(), "Feature vectors have different sizes");

    for (array_size_t j = 0; j < features.size(); ++j)
      features[j] += mf[j];
  }

  for (MeshGroup::GroupConstIterator ci = mg.childrenBegin(); ci != mg.childrenEnd(); ++ci)
    accumGroupFeatures(**ci, features);
