This is definitely not brand new news, so sorry if this is known by everyone else, but I figured I'd mention it considering the fact that when it was introduced to me just yesterday, it happened to be the first time I had seen it, so here goes:
Has everybody seen (or maybe I'm just last to the party – and I ought to ask "has anyone NOT seen?") a really neat project developed by a guy named Mark Wheadon that is dubbed "Velocity Painting"? If not, it's certainly worth a look, particularly because the post-processing Perl script needed to modify g-code generated from S3D is offered for download (and modification) by any interested, by visiting his github project page @ (github/MarkWheadon). Really cool, IMO.
Hope this finds everyone doing well and having a nice day,
