Suggesting inclusion of something does not imply suggesting the exclusion of something else. I don't know enough about either to comment. If any such (canvas included) are mentioned, a link to a small, but not trivial, example should be included - about a page of A4. -- (c) John Stockton, nr London, UK. ?@merlyn.demon.co.uk Turnpike v6.05 MIME.

The point is that inclusion of VML/SVG would complicate the FAQ IMO, and HTML Canvas is the foot in the door.

Authors get a simple mostly semantic standards-track declarative XML conforming color, text, geometry, animation, and interaction language. It is basically a script(able) DOM element that runs to produce a new output each time the data changes. The thing turns out to be useful for a wide range of nD+1 applications in html documents. A clever author can roll their own tree or scenegraph and produce interactive networkable transactions using GPU, OGL/OCL/Dx, WebGL, X3D, and any nD data structures to show most anything you want, completely integrated in the html5 document. For simple and complex examples of some current connections available using our newly-beloved html5 canvas element, please see x3dom.org. Best Regards, Joe

There is no call for embedding a tutorial in the FAQ, but a link or two would be worth their space. The FAQ, as an updating document, should briefly indicate the breadth of support in current and recent browsers. >Dr J R Stockton wrote: >> If any such (canvas included) are mentioned, a link to a small, but not >> trivial, example should be included - about a page of A4. > >How about this? >http://www.nihilogic.dk/labs/canvas_sheet/HTML5_Canvas_Cheat_Sheet.png It could be useful, if it could be read[*]. But it is not an example. The intention is to show by example what the language is like, not to teach by example. URL added to relevant page. [*] Font too small, even when printed. (Pity about the coloured bits; I'm out of red ink). And the material does not fit on 1 A4 on my printer. -- (c) John Stockton, Surrey, UK. ?@merlyn.demon.co.uk Turnpike v6.05 MIME.

Why not? That's the best example that I know (probably there are many examples that I do not know; but a nodding acquaintance with PostScript should not be uncommon). >For simple and complex examples of some current connections available >using our >newly-beloved html5 canvas element, please see x3dom.org. Nothing useful found there, primarily because of the smallness of the fonts. That which works of their "examples" are not examples but demonstrations; the code is not manifest. -- (c) John Stockton, Surrey, UK. ?@merlyn.demon.co.uk Turnpike v6.05 MIME.
