| | | Hi Darrell, How about some of the hair/accessories from the recent Lego Minifigure series? (URL) like the Cirus Clown's hair or the Caveman's hair would be very hard to model using normal methods. Being a Lego Star Wars fan I'd like to see the (...) (14 years ago, 16-Mar-11, to lugnet.cad)

| | | | | | Hi Reuben & Darell, (...) Yes, they look good. At first sight triangulation has too many triangles for a LDraw file, but it's easy to reduce. (...)

| | | | | | Hi Philo, I've sent you the STL file for the Anakin Skywalker hair piece and the Senate Commando helmet. I’m not really satisfied with how the front of the part looks; if you look at the picture on Peeron there’s a lot more definition in the hair (...)

In that case, I shall rescan without the head, from more angles, and with finer settings - I was trying (unsuccessfully) to try and limit the polygon count by scanning in lower resolution, but if you're using other software to (...)

If I make the triangle count more reasonable, the surface gets so smooth you might (...) (14 years ago, 23-Mar-11, to lugnet.cad)
