Axolotl 2.0

  • complete rework
  • new icon set
  • not (yet) backwards compatible
  • not all components translated (yet)
  • some new components not in 1.x


  • 190710: many new components
    • "real" gradient calculation added, on panel "Analysis"
    • axGradient renamed to axOverlay
    • distance field from mesh
    • distance field from surface
    • mesh, surface and pipe on new panel "Geometry"
