I attempted this approach many years ago and it just didn't work out very well at all. You need point-adjacency (connectivity) information to stitch the vectors together and that's lost in raster form. Geometry is effectively already in "vector" form, though, so we just need to project curves onto an image plane (prior to rasterization). > It reminds me Geo-graphical Information System (GIS) where it is > routine to use raster and vector maps.

There's a map accuracy joke in there somewhere. ;) >> In addition to the approach described on the ideas page, a similar feature >> could >> be intersecting a plane surface with objects and either integrating it as a >> visualization aide in the GUI or storing that result as vector output to a >> file. > > This is interesting. Do you mean "section cutting"? That is exactly what I mean. We have a ray tracer option that does it for raster output, but nothing that does the cut in NURBS form. That'd be a great project and awesome feature to have. Cheers!
