In my last post I showed off an extremely early version of a project in which a simple boat could be constructed from triangular surfaces. Since then I've made a lot of progress in all aspects of the game.

New features/improvements include:

• "Design" and "Simulation" modes split into separate levels
  
• Design mode now has a symmetry option, as well as the ability to view the vessel in wireframe to see the borders between surfaces
  
• Internal "compartments" are now handled properly; buoyancy calculations are disabled for sides of surfaces not on the exterior
  
• Designs can now be saved and loaded
  
• Main menu, almost like a real video game
  

• More tools in the editor to speed up building
  
• Different materials to build with, each with different densities and other stats
  
• Ability to change "thickness" of surface (not rendered visually, but affects weight and eventually armor value)
