From 206dbb81c7b54a32bf2a06c3812c070072b33e85 Mon Sep 17 00:00:00 2001 From: bubnikv Date: Mon, 2 Sep 2019 11:47:11 +0200 Subject: [PATCH] Fix of "Extra overhanging perimeters are added in 2.1.0-beta3" #2857 Two bugs were fixed: 1) An entry in the GLVolume index was not always created when it should have been. 2) Removing empty volumes from the list of GLVolumes did not update the GLVolume index. This is an old issue, but it likely surfaced now with the introduction of splitting the large GLVolumes into multiple shorter ones. --- src/slic3r/GUI/GLCanvas3D.cpp | 35 +++++++++++++++++++++++++++++++---- 1 file changed, 31 insertions(+), 4 deletions(-) diff --git a/src/slic3r/GUI/GLCanvas3D.cpp b/src/slic3r/GUI/GLCanvas3D.cpp index 7bfae3084..71bacd815 100644 --- a/src/slic3r/GUI/GLCanvas3D.cpp +++ b/src/slic3r/GUI/GLCanvas3D.cpp @@ -2152,9 +2152,36 @@ void GLCanvas3D::load_gcode_preview(const GCodePreviewData& preview_data, const if (!m_volumes.empty()) { - // removes empty volumes - m_volumes.volumes.erase(std::remove_if(m_volumes.volumes.begin(), m_volumes.volumes.end(), - [](const GLVolume* volume) { return volume->print_zs.empty(); }), m_volumes.volumes.end()); + // Remove empty volumes from both m_volumes, update m_gcode_preview_volume_index. + { + size_t idx_volume_src = 0; + size_t idx_volume_dst = 0; + size_t idx_volume_index_src = 0; + size_t idx_volume_index_dst = 0; + size_t idx_volume_of_this_type_last = (idx_volume_index_src + 1 == m_gcode_preview_volume_index.first_volumes.size()) ? m_volumes.volumes.size() : m_gcode_preview_volume_index.first_volumes[idx_volume_index_src + 1].id; + size_t idx_volume_of_this_type_first_new = 0; + for (;;) { + if (idx_volume_src == idx_volume_of_this_type_last) { + if (idx_volume_of_this_type_first_new < idx_volume_dst) { + // There are some volumes of this type left, therefore their entry in the index has to be maintained. + if (idx_volume_index_dst < idx_volume_index_src) + m_gcode_preview_volume_index.first_volumes[idx_volume_index_dst] = m_gcode_preview_volume_index.first_volumes[idx_volume_index_src]; + m_gcode_preview_volume_index.first_volumes[idx_volume_index_dst].id = idx_volume_of_this_type_first_new; + ++ idx_volume_index_dst; + } + if (idx_volume_of_this_type_last == m_volumes.volumes.size()) + break; + ++ idx_volume_index_src; + idx_volume_of_this_type_last = (idx_volume_index_src + 1 == m_gcode_preview_volume_index.first_volumes.size()) ? m_volumes.volumes.size() : m_gcode_preview_volume_index.first_volumes[idx_volume_index_src + 1].id; + idx_volume_of_this_type_first_new = idx_volume_dst; + } + if (! m_volumes.volumes[idx_volume_src]->print_zs.empty()) + m_volumes.volumes[idx_volume_dst ++] = m_volumes.volumes[idx_volume_src]; + ++ idx_volume_src; + } + m_volumes.volumes.erase(m_volumes.volumes.begin() + idx_volume_dst, m_volumes.volumes.end()); + m_gcode_preview_volume_index.first_volumes.erase(m_gcode_preview_volume_index.first_volumes.begin() + idx_volume_index_dst, m_gcode_preview_volume_index.first_volumes.end()); + } _load_fff_shells(); } @@ -5097,7 +5124,7 @@ void GLCanvas3D::_load_gcode_extrusion_paths(const GCodePreviewData& preview_dat unsigned int role = (unsigned int)(&filters - &roles_filters.front()); for (std::pair &filter : filters) if (filter.second->indexed_vertex_array.vertices_and_normals_interleaved.size() > MAX_VERTEX_BUFFER_SIZE) { - if (m_gcode_preview_volume_index.first_volumes.back().id != role) + if (m_gcode_preview_volume_index.first_volumes.back().type != GCodePreviewVolumeIndex::Extrusion || m_gcode_preview_volume_index.first_volumes.back().flag != role) m_gcode_preview_volume_index.first_volumes.emplace_back(GCodePreviewVolumeIndex::Extrusion, role, (unsigned int)m_volumes.volumes.size()); GLVolume& vol = *filter.second; filter.second = m_volumes.new_toolpath_volume(vol.color);
