Issues and possible improvements

Sorted by priority:

  • [IMPROVEMENT] Revert HMP::Actions::ExtrudeUtils::apply new vertex creation to the old method.
  • [IMPROVEMENT] HMP::Projection::jacobianAdvance is too defensive. Try working on one vertex at a time somehow.
  • [FEATURE] Add a negative weight factor for elements with multiple faces on surface in HMP::Projection::smoothInternal.
  • [BUG] HMP::Dag::Extrude and HMP::Dag::Refine relative fis and vis are cloned incorrectly during a paste operation, so I am recalculating them from scratch in HMP::Actions::Paste::fixAdjacencies_TEMP_NAIVE. This implies that:
    1. The otherwise flawless "Paste-the-same-way-to-get-the-same-result" principle is violated (not a big deal; GUI helps a lot here);
    2. I cannot profit from HMP::Refinement::Scheme::facesSurfVisIs until this is fixed.
  • [BUG] HMP::Actions::Root::~Root() leads to HMP::Dag::Node double free on app exit (I think the HMP::Dag::Node detachment system is broken).
  • [IMPROVEMENT] HMP::Refinement::Utils::apply should use HMP::Refinement::Scheme::facesSurfVisIs in place of HMP::Refinement::Utils::weldAdjacencies_TEMP_NAIVE (how do I rotate the scheme vertices and match the adjacent faces?).
  • [IMPROVEMENT] Improve HMP::Actions::MakeConforming either by implementing a balancing preprocessing phase, or by defining more adapter schemes.
  • [FEATURE] The extrude operation could automatically determine the number of parents, or at least give the user a warning in case of unintentionally duplicate vertices.
  • [IMPROVEMENT] HMP::Actions::MakeConforming performance can be improved a lot by keeping a queue of non-conforming refinements.
  • [FEATURE] Perhaps pasting a subtree should not preserve the source size (or maybe the choice could be left to the user).
  • [REFACTOR] HMP::Meshing::Utils is a dumpsite full of duplicated code. Keep the few essential primitives and throw everything else away.
  • [IMPROVEMENT] OGDF is overkill for what I need. Consider replacing it with a lighter implementation of the Sugiyama layout algorithm.
  • [IMPROVEMENT] The HMP::Gui::Widgets::DirectVertEdit scale and rotation implementation is a bit janky. (Also, a global axis-aligned translation feature would be welcome).
  • [FEATURE] Add a command to select all the vertices in a subtree.
  • [FEATURE] Allow the user to change the transform origin when editing vertices (or add a command to lock the origin in the current location).
  • [FEATURE] Add As-Rigid-As-Possible vertex editing support.
  • [REFACTOR] All the HMP::Meshing::Actions could be replaced with a set of more primitive actions (MoveVert, ShowElement, AddElements, WeldElements and ActionSequence maybe?).
  • [IMPROVEMENT] The HMP::Gui::DagViewer::Widget view should try to remain stable on layout change.
  • [IMPROVEMENT] The camera pan speed could be adjusted depending on the relative mesh position (as I do in the HMP::Gui::Widgets::DirectVertEdit translation operation).
