19:43 < matches> Well, GMP rationals applied to path bounds is faster than mpfr with 1024 bits applied directly
19:43 < matches> That's probably not a fair test though
+--- Day changed Sun Oct 12 2014
+14:53 < matches> Setting up the performance tests is a real pain if you want to actually include the really slow methods
+14:53 < matches> Well, restarting them can be painful
+14:54 < matches> Which means if you screw them up...
+14:58 < matches> Placing a limit of 30s per frame was perhaps a bit too generous
+15:05 < Pommers> THis is why you should use a build server
+15:05 < matches> Yeah except that's more effort to set up than it would save
+15:05 < matches> We even have one
+15:06 < matches> Motsugo could potentially run all these tests
+15:06 < matches> But it has to use a CPU renderer and is therefore shit
+15:06 < matches> Seeing the results in real time is a huge advantage
+15:06 * Pommers really needs to set up a proper Jenkins set up for UCC
+15:06 < matches> Oh, I'm not allowed to use my own laptop in the conference
+15:07 < matches> So if you want to fix the MinGW build for me... :P
+15:07 < matches> I'll see if sulix's magical GL version changes fixed anything later
+15:08 < matches> Ah
+15:08 < Pommers> I can give it a shot tonight. If you proof read some stuff for me right now
+15:08 < matches> I'm querying the FPS once the view has stopped being scaled
+15:08 < matches> Ok
+15:09 < matches> (I should record performance in the python script I think)
+15:09 < Pommers> tonight means after I finish work that is
+15:09 < matches> So 3am?
+15:09 < Pommers> Nah, like 6.30ish
+15:09 < matches> Honestly I'm probably just going to run a video
+15:10 < matches> But it'd be nice to say "Here's the binary with which you can reproduce the results"
+15:18 < matches> It's probably going to need to run on a Windows 95 presentation PC or something
+15:19 < matches> It has geometry shaders so it's probably beyond hope that it would work
+15:19 < matches> Hmm, do I need to prepare a response do a "Why didn't you just use <insert name of a language that isn't C++ here>"
+15:20 < matches> I seem to get that question every time I use C++ for anything
+15:20 < matches> Or alternately "Why didn't you use boost"
+16:19 < matches> sulix: What black magic should I do if I want to include the debug font in a screenshot...
+16:45 * matches resorts to ffmpeg instead
+16:45 < matches> With the disadvantage that 1 frame in a screen grap != 1 frame in the demo :(
+16:45 < matches> grap
+16:45 < matches> grape
+16:45 < matches> grab

+00:17 -!- bobgeorge33 is now known as Pommers
+13:34 < matches> My presentation is tonight
+13:34 < matches> Looks like Tim is back just in time to watch it!
+14:50 < sulix> In order to break things at exactly the wrong moment, IPDF has a profiler now.
+14:50 < sulix> It dumps the time spent in various functions at the end of each frame.
+15:10 < matches> That's pretty awesome
+15:11 < matches> Ok, time to test this pdf in adobe reader...
+15:11 < matches> And scream if it doesn't work
+15:19 * matches screams
+15:20 < sulix> Oh dear...
+15:20 < sulix> The power of adobe!
+15:24 < matches> I bet the videos don't work either
+15:26 < sulix> What format are they in?
+15:26 < matches> mkv
+15:26 < matches> They work
+15:26 < matches> I guess it was too much to expect pdflatex to produce a valid pdf
+15:35 < Pommers> Latex PDF? Got it working yet?
+15:55 < matches> No
+15:56 < matches> I have narrowed it down to
+15:56 < matches> "Cannot include graphics in slides"
+15:56 < matches> Which will make for an amazing presentation
+15:58 < matches> Ah
+15:58 < matches> Adobe doesn't support including pdfs within pdfs
+15:58 < sulix> What!?
+15:59 < sulix> Man, I've included pdfs within pdfs in pretty much every assignment I've submitted ever.
+15:59 < matches> I don't know
+15:59 < matches> That's the first place it shits itself
+15:59 * sulix ponders whether or not this may have affected marks.
+15:59 < matches> Debugging by repeatedly commentint out bits of TeX and recompiling is not very efficient and/or fun
+16:00 < sulix> Worst comes to the worst, take screenshots of all of your slides, I guess...
+16:00 < sulix> (Or download a windows binary for evince/etc and put that on the thumb drive)
+16:02 < matches> Yeah I'm supposed to be registering now
+16:25 < Pommers> matches: Send me the tex source and I'll try
+--- Day changed Wed Oct 15 2014
+10:38 < matches> Frames compiled it for me on Windows, so I survived
+10:40 < Pommers> Yeah. That's what I was going to do
+10:40 * Pommers should really set up that build server properly
+13:18 < matches> I might have promised a Windows version in the talk...
+13:18 < matches> Also saving, loading
+13:18 < matches> And...
+13:18 < matches> Shading
+16:05 < matches> I wonder if I can hack in a "draw" mode...
+16:05 < matches> Now that the conference is over, ANYTHING IS POSSIBLE
+16:06 < matches> (Except there's only two weeks left)
+16:06 < matches> ... < 2 weeks left

+14:48 < sulix> Far out: I'm looking up some IEEE GPU stuff, and Google keeps pointing me to your lit review.
+17:01 < matches> :S
+17:02 < matches> I need to muster the courage to write more of my report
+17:02 < matches> So tired
+--- Day changed Mon Oct 20 2014
+22:45 < sulix> So it turns out that the crazy multithreadedness of the control panel totally bollockses up the profiler.
+22:46 < sulix> Which explains the random crashing due to "impossible things happening" like "functions returning before their parents do".
+22:49 < sulix> The everything gets bollocksed when adding text bug is also fixed.
+22:50 < sulix> The magical invisible turtles bug remains.
+22:51 * sulix wonders if he should see the teenage mutant ninja turtles movie for an explaination.
+23:48 < sulix> For reasons unknown, I'm generating a lot of quadtree overlays with the exact same objects in them.
+23:48 < sulix> By which I mean the same {object_begin, object_end} pairs.
+23:49 < sulix> So lots of things are being rendered ~40 times, and many things aren't being rendered at all.
+23:51 < sulix> Actually, never mind, I'm just printing out the wrong thing in my debug statement.
+--- Day changed Tue Oct 21 2014
+00:48 * sulix has a lot of writing to do tommorrow.
+00:48 < sulix> By which I mean today.
