I have a mesh in a form like <a href="http://pastebin.com/8MRZqD74" rel="nofollow">this</a>. with a list of indices representing each polygon at the end. I need to generate a list of neighboring polygons for each polygon, and was wondering if anyone knows of an efficient algorithm to do this? The simplest way that comes to mind is for each polygon, check if every other polygon has two matching indices - but this looks like it involves a few nested loops. I don't mind using this, performance isn't a huge issue here, but yeah I'm just scouting for alternatives. There isnt any limitation on the max indices/vertices per polygon, but for simplicity's sake, lets just assume its 3 (so triangle polygons). Thanks for any help! :)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
