Wall Carving

The idea

  • Click on a wall to “mine” holes into it
  • The wall stores its own data and can render itself
  • Similar to the sculpting tool in Blender
  • OpenGL / C++

Initial plan

  • Wall class
    • Adding and removing vertices and edges
    • Rendering the wall (generating VBO)
    • Finding the click-wall intersection (Möller–Trumbore)
  • Mining algorithm
    • Moving vertices
    • Splitting long edges by creating new vertices
  • Movement
    • WASD + mouse
    • Crosshair
