RKALC Platform Updates & Development History

This page records significant RKALC platform updates in reverse chronological order. Entries reflect functional releases and capability expansions. If you require a specific update or have a feature request, please contact us via the contact page.

TribKALC Update

25 January 2026

  • TribKALC has been updated from pixel-based rendering to filled polygons using a Voronoi diagram, resulting in a major performance improvement.
  • All walls and cores now use additional segments, producing smoother results.
  • Zooming and panning are now enabled while results remain visible (previously, zooming or panning cleared the results).
  • Undo and redo are now enabled, with a maximum history depth of 50 steps.
  • The “Show Loads / Show Areas” button has been removed, as all information is now displayed in a single panel.
