Earlier today[1], helped my son with a raycasting issue and then ended up updating/extending the 2D shape intersection function in https://thi.ng/geom, which now also supports ray intersections with nested shape groups/hierarchies (via same single function call) and a new option to return all intersection points found (rather than just the first/closest). Both of these features are shown in a new example project (forthcoming) and in the anim below...
If you wanted to communicate how a proposed intersection or roadway redesign would look and feel to the public, what would you use?
I'm looking specifically for examples of tools that are fairly easy to use by non-experts and can create realistic renderings suitable for #public engagement.
