14:28 run4flat lungching, osfameron, +ops me and/or liddle?
14:30 lungching run4flat: done
14:30 run4flat thanks!
14:30 * run4flat wipes brow
14:30 lungching no problem
14:30 lungching :)
17:00 zpmorgan run4flat, long time :)
17:01 run4flat greetings, zpmorgan
17:01 run4flat busy around here. :-)
17:02 zpmorgan double pendulum:
17:02 zpmorgan http://www.youtube.com/watch?v=JfQ3rbQ5ehA
17:05 run4flat whoah, very cool!
17:05 run4flat chaos in action, folks!
17:06 zpmorgan :)
17:07 run4flat what's the integration scheme?
17:07 zpmorgan box2d :)
17:08 run4flat oh!
17:08 zpmorgan a link to the script is in the description
17:08 run4flat sweet!
17:08 run4flat interesting
17:09 run4flat funny term, though, because that's also the name of a function in PDL::Image2D
17:09 run4flat whereis box2d
17:09 liddle_piddle_bot run4flat: Found box2d in PDL::Image2D (http://pdl.sourceforge.net/​PDLdocs/Image2D.html#box2d)
17:10 run4flat Jeffrey should try to use Alien::Base to install Box2D's lib
17:11 run4flat or... wait
17:11 run4flat What language is it written in?
17:11 zpmorgan c++
17:11 run4flat Right, so this is just a wrapper
17:11 zpmorgan btw, gst-launch is a freaking versatile tool
17:13 run4flat hmm, beyond my ability for a quick grok
17:14 run4flat but... glad it's helpful. :-)
17:15 run4flat Once Box2D has some docs, maybe it should be added to perl4science
17:17 zpmorgan maybe also Inline::Octave?
17:18 run4flat Inline should probably have its own section
17:20 zpmorgan so is PDL::Graphics::Prima mainly for plotting?
17:21 zpmorgan what if I have an image piddle that I'd like to turn into a Prima::Image?
17:21 run4flat There's a module for that
17:21 run4flat PDL::PrimaImage, I believe
17:21 zpmorgan okay, didn't see it.
17:22 run4flat it was the first Prima thing that I ever noticed, many years ago
17:31 zpmorgan eh, I think I'll pass on that module. i'll just use pack again

18:13 liddle_piddle_bot Welcome back, zpmorgan
19:38 zpmorgan oh, how nice. down is not only up, but rgb is bgr
19:41 zpmorgan so maybe it'll only be flipped right-to-left if the whole array is reversed before it's packed.

20:22 sivoais joined #pdl
20:57 run4flat hmm, yes. :-)
20:57 run4flat More appropriately, up is up. :-)
20:58 zpmorgan that's with data=> pack(reverse $pdl->list)
20:58 run4flat as for rgb unpacking, I use the math I've seen elsewhere, namely: red >> 16 + green >> 8 + blue
20:59 run4flat well, yeah, that makes sense, too
