Afaik a canvas interface is where you draw to a bitmap by issuing calls in a procedural style (eg web canvas, cairo graphics etc). This is in contrast to vector graphics where you build an object hierarchy to be rendered.

That's almost backwards from my understanding of those terms, but oh well ....

  Sure, can you share your understanding?

    Vector graphics: drawing stuff by issuing commands to render specific simple geometric elements (lines, rects, triangles, circles) Canvas: a context in which to place "objects" in 3 dimensions (x, y and z), and have them appropriately re-rendered when necessary (motion, object addition/removal)

      Interesting, maybe canvas is an overloaded term.

      After thinking about it, »a context in which to place "objects"« sounds like a scene graph.
