03:58 AM Jak_o_Shadows: ok, woke up, got back.
06:09 AM Jak_o_Shadows: My bezier curve code is buggered up: http://pasteall.org/pic/index.php?id=117283
06:46 AM veverak: hmm
06:46 AM veverak: somehow
06:46 AM veverak: I want to build a ship hull
06:46 AM veverak: (for a robotic ship obviously)
07:28 AM Jak_o_Shadows: Hmmm. Maybe the circle is being tricksy
07:28 AM Jak_o_Shadows: nah, shouldn't be.
07:29 AM Jak_o_Shadows: I'm trying simulated annealing to find that bezier curve.
07:30 AM Jak_o_Shadows: Hmm. Maybe I have a degreees radians issue
07:40 AM Jak_o_Shadows: ah. Piss.
07:40 AM Jak_o_Shadows: I need to somehow let my bezier curve not be continous
07:40 AM Jak_o_Shadows: Becuase angles are a circular type space, and the regular cartesian y is not
07:42 AM Jak_o_Shadows: That is 100% my issue
07:44 AM Jak_o_Shadows: veverak: https://bpaste.net/show/e07f73ad2869 is what I have at the moment.
07:44 AM Jak_o_Shadows: The issue is 100% how I deal with the endpoints, and making it smooth and CTS.
07:49 AM * veverak is not sure he udnerstands bezier
07:49 AM Jak_o_Shadows: You give it 4 points. Two the curve passes through exactly, the other two just kinda drag the curve out a bit
07:56 AM Jak_o_Shadows: I need periodic boundary conditoins
07:56 AM veverak: :)
08:00 AM EastsideR: I learnt about simulated annealing at class but never fully understood it :(
08:40 AM veverak: ok
08:40 AM veverak: so fun for the rest of day
08:40 AM veverak: is redrawing the shape of the ribs
08:40 AM veverak: in cad
08:41 AM Tom_itx: shouldn't be that hard
08:41 AM Tom_itx: what cad are you using?
08:44 AM veverak: qcad

02:19 PM Tom_itx: 's back
02:44 PM deshipu: rue_house: you are in the wrong timezone
02:55 PM mrdata: whereas i am definitely in the right timezone

04:28 PM robopal: hahaha
04:31 PM Snert_: poor bot :( *sniff*
04:32 PM Snert_: At least I get to see it's undercarriage/drive wheels assembly.
04:32 PM Snert_: was wondering how they were doing it - tracked or wheeled.

11:33 PM Tom_itx: veverak, it's taking shape...
11:36 PM Tom_itx is now known as Tom_L
11:36 PM Tom_L: rue_shop2, what's up?
11:46 PM rue_shop2: g3000
11:47 PM rue_shop2: wrong terminal please dont goto
11:48 PM rue_shop2: i THINK i finished up the board for the screw sorter cart
11:48 PM rue_shop2: maybe I can do the box for it tommorow
11:51 PM rue_shop2: g3000
11:51 PM rue_shop2: grrr
