 21:15 < matches> I hope that's not the conference abstract
 21:15 < matches> I also really hope we're allowed to use our own computer and things in the conference
 21:16 < matches> Also I really hope that if I can use my own computer it doesn't decide to shit itself anyway just to spite me
+--- Day changed Mon Aug 18 2014
+17:06 < matches> Good news and bad news!
+17:07 < matches> The kerning now appears to kern in the right direction
+17:07 < matches> But this means "BleedingCowboys.ttf" works
+20:30 < sulix> It's a pain to look up clipping of beziers, because there's a separate technique for doing something else called "bézier clipping"
+20:40 < matches> Baha
+20:41 < matches> I'm basically just procrastinating with Qt
+20:41 < matches> I mean
+20:41 < matches> Doing *awesome* things with Qt
+20:48 < sulix> I am looking with considerable envy at SolveQuadratic().
+20:49 < sulix> SolveCubic() will get very ugly.
+20:49 < sulix> Assuming I don't just sample the cubic at 100 points and look for roots.
+20:49 < matches> Haha
+20:49 < matches> Newton Raphson?
+20:50 < sulix> Very tempting.
+20:50 < matches> Then you can solve any bezier!
+20:50 < matches> Then we can put in Quintics!
+20:50 < sulix> Solving cubics exactly is not fun.
+20:50 < sulix> Dear god no.
+20:50 < matches> Imagine how many loops a quintic could have...
+20:51  * sulix cries quietly in the corner.
+20:53 < matches> So I'm calling AddText with sane values and nothing is happening :(
+20:56 < sulix> With or without quadtree?
+20:56 < sulix> With quadtree, everything is broken if you try adding things.
+20:56 < sulix> Because they won't be added to a node.
+20:57 < matches> No quad trees I think
+20:57 < matches> Yeah no quad tree
+21:00 < matches> Wait I think we need to rebuild the buffers or something
+21:07 < matches> Ah, ForceRenderDirty()
+21:14 < matches> I don't think the scale of our text is quite right?
+21:14 < sulix> Well, the scale of everything is wrong, but it's entirely possible that the text is _extra wrong_
+21:16 < sulix> In theory, the "scale" input to addText is the "height" of a character.
+21:19 < matches> Mmm
+21:19 < matches> I'm trying to add text relative to the current view
+21:19 < matches> But it isn't consistent
+21:19 < matches> When I go to a different view it is definitely not adding it in the same relative place
+21:20 < matches> The scale and positions aren't *already* relative are they?
+21:22 < sulix> Not to the view...
+21:24 < matches> What are they relative to?
+21:24 < matches> Anyway instead of fixing that bug I'm adding more
+21:25 < sulix> Umm... The bounding box maybe?
+21:25  * sulix investigates.
+21:26 < sulix> Scale and position should (I think) be normal, document coordinates.
+21:26 < matches> Odd
+21:26 < matches> Oh well
+21:26 < matches> Having Qt is totally worth it by the way
+21:27 < matches> Although it is still slightly embarrassing that it has its own SVG parser
+21:27 < matches> Ours is better!
+21:27 < matches> It has Reals everywhere!
+21:27 < matches> Except where it constructs Real from floats...
+21:27 < matches> And converts them to floats...
+21:28 < sulix> Thesis title should be "Keepin' it real: Staying afloat on the sea of document precision"
+21:31 < matches> Bahaha
+21:31 < matches> That is brilliant
+21:32 < matches> The Qt stuff is never deleting anything
+21:32 < matches> I suppose I should fix that at some point
+21:33 < matches> So basically it is a state machine and you use the menu to change the state
+21:33 < matches> Pressing OK does something depending on the state
+21:34 < matches> And there is a single text edit you can type stuff into
+21:34 < matches> In theory it can hide/show different widgets depending on the state
+21:34 < matches> I feel like I should add a "Generate Thesis Title" widget now...
+21:35 < matches> Also I can sort of see the appeal of lambdas for GUI programming now
+21:35 < matches> But I have a feeling they would totally break Qt anyway
+21:49 < matches> ...
+21:49 < matches> Ok sometimes the text gets added upside down...
+21:49  * sulix disclaims any and all responsibility for that.
+21:51 < matches> Yes!
+21:51 < matches> I finally did that thing I was saying I'd do for like 3 weeks
+21:51 < matches> Zoom in to floating point limit
+21:51 < matches> Add SVG
+21:51 < matches> Watch it explode!
+21:52 < sulix> Oooh...
+21:52 < matches> It is glorious
+21:54 < matches> We need to be a bit careful with thread safety in qt
+21:55 < matches> Really we should be able to request that the qt thread call UpdateAll itself
+21:55 < matches> Rather than calling it directly from the viewer thread
+21:55 < matches> But I'm not sure how that's done
+21:55 < matches> There's all this stuff about "Cross thread signals" on the internet
+21:56 < matches> It seems you can hide/show things but not much else
+22:47 < matches> Bah you pushed things!
+22:55  * sulix proclaims the new features as excellent and promptly goes to bed.
