C++ (Cpp) compute_color_map Examples

Example #1

void
Scene_c3t3_item::c3t3_changed()
{
  // Update colors
  // Fill indices map and get max subdomain value
  indices_.clear();

  int max = 0;
  for (C3t3::Cells_in_complex_iterator cit = this->c3t3().cells_in_complex_begin(),
    end = this->c3t3().cells_in_complex_end(); cit != end; ++cit)
  {
    max = (std::max)(max, cit->subdomain_index());
    indices_.insert(cit->subdomain_index());
  }
  for (C3t3::Facets_in_complex_iterator fit = this->c3t3().facets_in_complex_begin(),
    end = this->c3t3().facets_in_complex_end(); fit != end; ++fit)
  {
    max = (std::max)(max, fit->first->surface_patch_index(fit->second));
    indices_.insert(fit->first->surface_patch_index(fit->second));
  }

  d->colors.resize(max + 1);
  compute_color_map(color_);

  // Rebuild histogram
  build_histogram();
  
}
