Interface (or Concept) Canvas: |
|||
Canvas canvas(width, height, ...); Constructs a Canvas with given dimensions |
|||
canvas[x][y]...[z] Returns a (const) reference to an element |
|||
canvas.plot(position) Plots on the canvas (where position is normalized, ie in the unit-cube) |
|||
canvas.size<N>() gives width/size for the given dimension N. |
|||
canvas.begin() .end() gives iterators to the elements (directly) |
