| 03:21.42 | brlcad | starseeker: did you see the sharpen comparison? (can you read psd's?) |
| 04:06.57 | starseeker | brlcad: I saw the comparison image you put up on bz |
| 04:08.03 | starseeker | er brlcad.org rather |
| 04:09.32 | starseeker | Does Gimp have anything like Photoshop's intelligent sharpen? |

| 17:11.27 | brlcad | starseeker: I think manual is the way to go if hardbound is the end goal ;) |
| 17:11.29 | brlcad | looks great |
| 17:20.39 | brlcad | otherwise, this looks like it's doing a similar algorithm via manual steps: http://www.gimp.org/tutorials/Smart_Sharpening/ |
| 17:25.03 | jonored | Seems like it should only be a bit of scheme work to make that into automatic... |
| 17:32.41 | brlcad | ah, and looks like he redid it with a little fewer steps: http://www.gimpguru.org/Tutorials/SmartSharpening2/ |
| 17:36.25 | brlcad | yeah, script-fu or python-fu should do the trick to tie it together into an automation |
| 18:10.44 | DanielFalck | brlcad: fyi- I am happily making coils of pipe in brlcad this morning. It's the little things in life .... |

| 20:26.51 | brlcad | DanielFalck: hehe, totally understand ;) |
| 20:27.48 | DanielFalck | brlcad: here's another question for you: is it possible to extrude a different closed shape along a path, similar to 'pipe' |
| 20:28.11 | DanielFalck | like a triangle to make a thread form? |

| 20:31.21 | brlcad | ahh, alas, no -- there was a summer of code project to implement exactly that but it wasn't completed |
| 20:31.42 | brlcad | the project involved implementing revolve and sweep, they only got through most of revolve |
| 20:31.43 | DanielFalck | ok, no problem |
| 20:32.07 | DanielFalck | so we can't revolve a profile yet either? |
| 20:32.38 | brlcad | no, revolves are mostly complete -- there are a few loose ends still but most of it is done |
| 20:33.16 | DanielFalck | that's good news. I'll be using a lot of 'revolve' commands- I do a lot of turning on cnc lathes |
| 20:33.48 | brlcad | the biggest part of revolve that wasn't completed was support for bezier curves -- right now it's limited to line segments and arcs iirc |
| 20:34.10 | DanielFalck | well that's perfect for me- I only need lines and arcs for what I do |
| 20:34.21 | DanielFalck | can you give me a little lesson on trying it out? |
| 20:34.31 | DanielFalck | I compiled svn this week |
| 20:35.25 | brlcad | have you made an extrude yet? |
| 20:35.32 | brlcad | making a revolve isn't much diferent |
| 20:35.44 | DanielFalck | oh yes, got that working |
| 20:35.57 | DanielFalck | thanks for all the help , by the way |
| 20:44.49 | brlcad | so with revolve, you make a sketch -- ideally one that is a right-contour of your shape with positive values -- then create a revolve that positions and uses that sketch with an angle of revolution (see the 'in' command) |
| 20:50.22 | DanielFalck | so is the command 'in rev1 revolve' etc... ? |
| 20:57.29 | DanielFalck | brlcad: what is the 'start plane' in revolve? thanks |
| 21:04.48 | DanielFalck | ok, got it to work |
