Thanks for pointing out Google infographics; didn't know that it could also display equations. Preferably, I would like it to display using Morphs so that I can have more options for interactivity e.g. editing and drag-and-drop. I already have a parser implemented; this whole thing is part of a bigger project and I'm working on the display part currently. What happens in Pier-Math? I only know that Pier is a CMS on Seaside so I'm not too familiar with the internal details. I assume that Pier-Math has some parser and renders to HTML (perhaps using MathML or something). Does it render to Morphic? Are there any existing things that can render using Morphic directly in the Smalltalk image? Thanks. -- Nick Lukas Renggli wrote:

The Google infographic web service is probably the simplest one to use (there are many others): http://code.google.com/apis/chart/infographics/ You post a formula and get back a PNG that you display as a morph. Should be doable in 1 line of Smalltalk code.

Also works with HTTPSocket instead of ZnClient, if you don't use Zinc:

(ZnClient getPng: 'http://chart.googleapis.com/chart?cht=tx&chl=' , 'a^2+b^2=c^2' encodeForHTTP) asMorph openInHand

...

Of course you can do the processing also yourself, but this is more complicated. Pier-Math does that for example.

Hi

I'm working with some simple math equations and am looking for a nicer way to display them. Is there any existing work that I might be able to re-use/build upon?

For instance, given this equation, (1+2/3)*4 I would like to see it displayed like the Equation Editor in Microsoft Word or the equations in a Mathematica notebook. See attached screenshots:

I'm not looking for anything fancy. Something simple to get me started would be helpful as well.

I looked briefly at Dr. Geo but I don't think it support displaying equations in that manner.

Thanks!
