02:15 <Cepheid> I have no idea.
02:15 <Cepheid> Be careful with it though. The memory leaks reported in my program were all caused by the i915 driver.

02:16 <DashedRainbows> WoL should run It I think

02:17 <Cepheid> Yes.
02:18 *** Joins: ADragonDreaming (IceChat9@Pony-tpdjag.livnmi.sbcglobal.net)
02:18 <RazorSharpFang> Hrmm... is that an integrated GPU?
02:18 <Cepheid> Yes.
02:19 <Cepheid> It is the Intel driver for Intel's IGP GPUs.
02:20 <Cepheid> It likely isn't actually leaking memory. It is improbable that it would be full of that many leaks.
02:21 <Cepheid> Or errors. Likely it is just valgrind picking certain bits of driver work as leaks or errors.
02:28 *** Quits: ADragonDreaming (IceChat9@Pony-tpdjag.livnmi.sbcglobal.net) (Ping timeout: 121 seconds)
02:29 <Cepheid> Probably along the lines of "hey GPU, here is a buffer of data." And the GPU goes "okay, I'll take care of it from here." Since the driver no longer holds ownership, it is free from having to deallocate. This looks like a failure to free some memory to Valgrind, due to how it works.
02:30 <RazorSharpFang> Does Valgrind operate on the compiled code directly? I thought it would do analysis of C/C++ code.
02:30 *** Joins: ADragonDreaming (IceChat9@Pony-tpdjag.livnmi.sbcglobal.net)
02:31 <Cepheid> It depends on how it's used I believe. In compiled code, it replaces functions that manipulate, allocate or deallocate memory.

02:42 <Cepheid> Ahyhow, Razor, Valgrind checks for memory leaks, memory misuse and the like. You run it by doing "valgrind <executable>". The executable is specified as if you were running the program from wherever it is. Thus for me: valgrind ./EngineTest

14:15 <Cepheid> How goes it, Razor?
14:18 <RazorSharpFang> Pretty good.
14:18 <RazorSharpFang> I checked my local hardware store, but they don't sell graphite electrodes.
14:20 <Cepheid> What do you need them for?
14:21 <RazorSharpFang> I was looking to electrolyse water to produce hydrogen and oxygen gas. The classic electrolysis.
14:21 <Cepheid> Okay, not gonna ask why, buuuut whatever.
14:23 <Cepheid> Meanwhile, I'm trying to debate what's the better approach for what I'm doing here. I tried an alternative approach of setting up the tile rendering engine. Let's me retain the shader program I have, but reduce the effort for rendering scenes.
14:23 <Cepheid> On the other hand, if anything changes in the scene, I have to rebuild the buffer from scratch. But that's relatively painless to do, apparently.
14:23 <RazorSharpFang> Me, I'm just happy to be able to draw shapes on the screen with accelerated graphics. :3
14:25 <Cepheid> Heh.

14:28 <Cepheid> It'd be great if I could pull off say, GL_TRIANGLE_STRIP. But for *THAT* to work..
14:30 <Cepheid> Generating a grid's a pain in the ass with a GL_TRIANGLE_STRIP. That said, it's less data to pass to the GL, and *SUPPOSEDLY* faster.
14:33 <Cepheid> ... And it's useless, as I just remembered a detail about it. o3o
14:34 <Cepheid> It re-uses vertices, and I need each vertex to be distinct, specific to a given tile.
14:35 <RazorSharpFang> ... How do you draw a triangle in SDL?
14:38 <Cepheid> Can I see your code first? Something you stated the other day made me curious.
14:38 <Cepheid> It sounds like you're using SDL_CreateWindowAndRenderer.
14:38 <RazorSharpFang> Whats about it?
14:38 <Cepheid> That is, creating a window and renderer.
14:38 <Cepheid> Rather than a window and GL context.
14:39 <RazorSharpFang> `SDL_Renderer * renderer = SDL_CreateRenderer(window, ... )` is where I grab my renderer from.
14:39 <RazorSharpFang> With `window` referring to the pointer handle given to me by SDL_CreateWindow()
14:39 <Cepheid> Of course.
14:40 <Cepheid> You're using SDL's 2D rendering engine. That's different from OpenGL.
14:40 <RazorSharpFang> It looks like I might have to actually use OpenGL.
14:41 <Cepheid> Here, I'll publish some simple code that'll get OpenGL set up for ye. I'll set it to 2.1, because that allows immediate mode.

14:55 <Cepheid> An unfortunate side effect, yes. You may also want to look into the GLEW library.
14:55 <RazorSharpFang> Dang it, more tutorials from SDL 1.2
14:56 <Cepheid> https://pastebin.com/6jWe2bkA
14:57 <RazorSharpFang> Yeah, that's a private paste. Only the creator can see it.
14:57 <Cepheid> This sets up a basic 640x480 SDL window, sets the projection matrix to a matrix such that the coordinates go from 0 to 640, 0 to 480.
14:57 <Cepheid> Oh, sorry.
14:57 <Cepheid> I thought maybe it'd let me share it if it was private anyways.
14:57 <Cepheid> https://pastebin.com/6jWe2bkA Try again.
14:57 <RazorSharpFang> There should be an option for "required link"
14:58 <Cepheid> Unlisted.
14:58 <RazorSharpFang> That's the term I wanted to say but couldn't think of quickly enough for my patience.
14:58 <Cepheid> Heh.
14:58 <Cepheid> In any case, you'll need GLEW to compile it.
14:58 <Cepheid> It's really, really recommended you use GLEW or some other similar library.
14:59 <RazorSharpFang> Say, which version of OpenGL would I want to use if I also wanted to target android?
14:59 <Cepheid> To target Android? OpenGL ES is what you want.
14:59 <Cepheid> I don't know if SDL can make a GL ES context.
14:59 <Cepheid> Let me see if there are frameworks that can do that.
15:00 <Cepheid> You can set the profile mask to SDL_GL_CONTEXT_PROFILE_ES.
15:00 <RazorSharpFang> I can still draw triangles under that, right? :3
15:00 <Cepheid> I'm not sure if it'll work under Windows, though, as an ES context is specific to mobile devices.
15:01 <Cepheid> If you explicitly want to create Android apps using OpenGL ES, I would advise actually making an Android project.
15:01 <Cepheid> Using C/C++ would require using an Android Native execution library.
15:01 <RazorSharpFang> I've heard that SDL does support android.
15:02 <Cepheid> Let's see..
15:02 <Cepheid> Yeah, there's a tutorial for it.
15:03 <Cepheid> http://www.dinomage.com/2013/01/howto-sdl-on-android/
15:03 <Cepheid> http://blog.stuff-o-matic.com/post/2013/10/20/ASGP-s-Android-Port-Part-IV%3A-building-the-APK And this too.
15:03 <Cepheid> I haven't tried either, so I can't comment on them.
15:04 <RazorSharpFang> Hmm, I don't have glew. Where'd you grab glew from?
15:04 <Cepheid> http://glew.sourceforge.net/
15:05 <Cepheid> But yeah, you really, really should use GLEW when you can.
15:05 <Cepheid> There's thousands of different functions from hundreds of extensions.
15:07 <Cepheid> BRB.
15:08 <RazorSharpFang> I'm going to have to figure out how to link this...
15:09 <Cepheid> What compiler you using?
15:09 <RazorSharpFang> Visual Studio
15:09 <Cepheid> Two ways I know of, provided the libraries are in the right place.
15:10 <Cepheid> First, and probably the most portable manner since non-supporting compilers can just ignore it..
15:10 <RazorSharpFang> Am I not supposed to include gl before glew?
15:11 <Cepheid> Yeah, it includes the GL files for you.
15:11 <RazorSharpFang> Ah makes sense.
15:11 <Cepheid> You just need to include glew.h
15:11 <Cepheid> Meanwhile, for linking, assuming the files are in the right place..
15:11 <Cepheid> "#pragma comment(lib, glew32.lib)" I think should work.
15:11 <Cepheid> I haven't used the pragma method of linking in a long time.
15:12 <Cepheid> Which is silly since it's probably the most portable thing Microsoft has ever done.
15:12 <Cepheid> Compilers are free to ignore the #pragma line if they don't understand it, so it won't cause problems with other compilers.
15:13 <Cepheid> Apparently it'll work with clang.
15:15 <Cepheid> GCC, not so much.
15:16 <Cepheid> The other way is to specifically list the libraries in the project settings.
15:16 <Cepheid> Open the project settings, go to C/C++ section, there should be a linker/library subsection.
15:16 <Cepheid> You can add extra libraries there. You specify them in a window where you list one library per line.
15:17 <RazorSharpFang> Yeah, I need to do that as I'm getting unresolved external symbols.
15:18 <Cepheid> Even with the #pragma comment(lib, ...)?
15:18 <Cepheid> Oh.
15:18 <Cepheid> You're supposed to enclose the library name in quotes.
15:18 <Cepheid> #pragma comment(lib, "glew32.lib")
15:18 <RazorSharpFang> I have done that, yes.
15:19 <Cepheid> Hum.
15:20 <Cepheid> I'll have to investigate, then.
15:21 <RazorSharpFang> It's specifically complaining about __imp_glMatrixMode
15:21 <Cepheid> That'd be OpenGL.
15:21 <Cepheid> opengl32.lib
15:22 <Cepheid> You'll need to link in SDL2.lib and SDL2main.lib as well.
15:22 <Cepheid> I assume you've figured that out though.
15:22 <RazorSharpFang> It's compiled!
15:22 <RazorSharpFang> But the program can't start because it's not finding glew32.dll :3
15:23 <RazorSharpFang> Just a quick fix away.
15:25 <Cepheid> That means either putting it in the executable directory or the Windows/System32 folder.
15:25 <Cepheid> Or WoW64 folder. I forget which one, on 64-bit.
15:25 <RazorSharpFang> ... Oh no.
15:26 <Cepheid> What?
15:26 <RazorSharpFang> OpenGL has 0 on the bottom and counts vertically up doesn't it?
15:26 <Cepheid> Hmm?
15:26 <Cepheid> What do you mean?
15:26 <Cepheid> Oh, that.
15:26 <Cepheid> Do you want it the inverse?
15:26 <RazorSharpFang> [0,0] is bottom left isn't it?
15:26 <Cepheid> Yeah, I know what you mean now.
15:26 <Cepheid> Do you want [0,0] at the top-left?
15:26 <RazorSharpFang> For whatever reason that seems to be the norm everywhere else.
15:27 <Cepheid> Yes or no. :P
15:27 <Cepheid> Go to the glOrtho function, line 56.
15:27 <Cepheid> Or therabouts.
15:27 <RazorSharpFang> Is it just swapping top and bottom inputs? :3
15:28 <Cepheid> The third and fourth parameter specify bottom and top. Swap them so the function call reads glOrtho(0, 640, 480, 0, -1, 1)
15:28 <Cepheid> OpenGL by default prefers [0,0] be at the lower-left, because mathematics. But there's nothing stopping you from swapping it.
15:28 <Cepheid> Since it's a 3D API, you can just set up an appropriate matrix.
15:29 <RazorSharpFang> What does orthographic projection even mean?
15:29 <Cepheid> No perspective divison.
15:29 <Cepheid> ER, division*
15:29 <Cepheid> It basically just flattens everything before presenting it to the screen.
15:29 <Cepheid> It results in "2D" style rendering.
15:30 <Cepheid> If you want more traditional 3D, you use glFrustum instead.
15:31 <Cepheid> Meanwhile, an explanation of the setup you're using. You're currently in OpenGL 2.1. https://www.khronos.org/registry/OpenGL-Refpages/gl2.1/
15:31 <Cepheid> It's pretty much the most compatible version of OpenGL, but lacks a lot of later functionality.
15:31 <Cepheid> You might still be able to get that functionality due to extensions, which GLEW handles.
15:31 <RazorSharpFang> As long as I can draw anti-aliased triangles I should be good.
15:32 <Cepheid> Ah, for anti-aliasing..
15:32 <Cepheid> You need to set another GL attribute.
15:32 *** Joins: Persona (Tilde@Pony-joa7q9.dgbc.9fgu.6000.2605.IP)
15:34 <Cepheid> Add to the SDL_GL_SetAttribute lines the following: SDL_GL_SetAttribute(SDL_GL_MULTISAMPLEBUFFERS, 1); and then...
15:34 <Cepheid> SDL_GL_SetAttribute(SDL_GL_MULTISAMPLESAMPLES, #); where # is the number of samples. Usually 1, 2, 4, 8 or 16.
15:34 <Cepheid> Alternatively, just force-enable it in your video card's settings.
15:35 <RazorSharpFang> Which one is likely to be most compatible?
15:35 <Cepheid> Context is needed. Do you mean the numbers 1, 2, 4, 8, 16, or the force-enable?
15:36 <RazorSharpFang> The numbers yeah.
15:36 <Cepheid> Pretty much any of them.
15:36 <Cepheid> The more you use, the slower the performance, but the better the quality.
15:37 <Cepheid> If you want a conservative limit, set it to no higher than 8.
15:37 <Cepheid> My advice for learning OpenGL, Razor?
15:38 <Cepheid> Right now, what I showed you is called immediate mode.
15:38 <Cepheid> That is, you issue commands, and they're performed immediately. Unfortunately, immediate mode isn't the most performant.
15:38 <Cepheid> It's great for simple learning and practice, but you won't use it in full, complete programs.
15:38 <Cepheid> You'll want to learn about Vertex Array Objects and Buffer Objects.
15:39 <Cepheid> These are the modern ways of improving throughput in rendering.
15:39 <Cepheid> It's harder to use, though.
15:39 <Cepheid> Like, a lot harder.
15:40 <RazorSharpFang> Because g-cards are so fast, it's better to give them data in big chunks right?
15:41 <Cepheid> There's a few reasons, actually.
15:42 *** Quits: danwellby (danwellby@The.lone.griffon) (Connection closed)
15:42 <Cepheid> I believe the glBegin(), glVertex(), glEnd() sends it either piecemeal, or collects the data into a buffer, then shoves it over to the GPU.
15:42 <Cepheid> In either case, the same buffer is not re-used.
15:43 <Cepheid> So there's a data transfer from CPU to GPU side each time, which kills performance.
15:43 <Cepheid> Vertex Array Objects and Buffer Objects are different. Vertex Array Objects save a bunch of state information about buffer arrays of varying type with themselves.
15:44 <Cepheid> And they're stored on the GPU-side, so switching them around is fast and easy.
15:44 <Cepheid> Buffer Objects, meanwhile, are pretty much what their names suggest. They're allocated buffers on the GPU side.
15:44 *** Joins: danwellby (danwellby@The.lone.griffon)
15:45 <Cepheid> You create 'em, shove data into 'em, and the system does a data transfer when best appropriate. Then utilize them in drawing commands. Since the data's all on the GPU side already, it's fast to use, and the buffer isn't immediately discarded after use.
15:46 <Cepheid> Of course, this implies staticness. You can map regions of the buffer back to CPU-side to modify them(Some even go so far as to let you modify GPU memory, depending on implementaton.) and make changes to the buffer.
15:46 <Cepheid> Ultimately, the difference in performance is insane.
15:46 <Cepheid> But, like I said, harder to set up.
15:48 <Cepheid> If I tried to use my current engine by drawing each tile separately with glBegin(), glEnd() calls, the performance would drop down into the sub-60 range of FPS.
15:48 <Cepheid> The current setup is around 1000-2000 FPS range, depending on the tiles.
15:49 <RazorSharpFang> Hmm, I'm not getting anything drawn on my code, but yours is working. Hmmmm.
15:49 <Cepheid> Show me yer code.
15:49 <RazorSharpFang> https://pastebin.com/MHV4aaYF
15:51 <Cepheid> Because you're not drawing within the bounds of the screen.
15:51 <Cepheid> What're you trying to do?
15:52 <RazorSharpFang> How is it not within the bounds of the screen?
15:53 <Cepheid> SCREEN_WIDTH = 960. 960 - 25 = 935. 935 & 960 > 640. Same with SCREEN_HEIGHT stuff >= 480.
15:53 <RazorSharpFang> I was originally using my SCREEN_WIDTH/HEIGHT values, but that wasn't working.
15:53 <RazorSharpFang> I'm still drawing the original triangle at (25,25,50,50,75,75)
15:54 <Cepheid> Yeah, because 25/50/75 < 640 and 480.
15:54 <Cepheid> Are you trying to set up a 16:9 viewport size?
15:54 <RazorSharpFang> Yeah.
15:54 <Cepheid> Change the 640 and 480 in the glOrtho and the glCreateWindow with your SCREEN_WIDTH and SCREEN_HEIGHT respectively.
15:55 <RazorSharpFang> I'm confused as to how [25,25] isn't a pixel in the viewport.
15:56 <Cepheid> Hooboy, this'll take some time to explain.
15:57 <Cepheid> Vertices are arbitrary, unitless. By themselves, they don't represent pixels. They just represent points for primitives like triangles, lines, points and squares.
15:57 <Cepheid> What translates their actual location is a vector-matrix multiply.
15:58 <Cepheid> In typical graphics, you have three matrices. A Model matrix, which represents the "world." Any transformations applied to it are relative to an origin point of (0,0,0)
15:58 <Cepheid> Then you have your View matrix. This is the camera.
15:58 <Cepheid> You adjust the view matrix, your viewpoint changes.
15:58 <Cepheid> Then you got the projection matrix.
15:59 <Cepheid> This takes everything and translates it to screen coordinates.
15:59 <Cepheid> Then clipping is performed by a viewport specification.
16:00 <Cepheid> By default, your world and view matrices are set to the identity matrix, so vectors passed in come out the same.
16:00 <Cepheid> That is, (1,1,1) * Identity Matrix = (1,1,1)
16:02 <Cepheid> Guh, this explanation is actually hard to do.
16:04 <Cepheid> The projection matrix maps coordinates to the "screen". So for example, if the projection matrix is set to 0, 1, 1, 0(left, right, bottom, top), then a vertex at 1/1 will be at the upper-right corner of the screen.
16:04 <RazorSharpFang> I've gotten this so far: (Text done in paint) https://imgur.com/Lf0oCax
16:04 <Cepheid> If you specified 0.5/0.5, the vertex would be placed in the middle of the screen.
16:05 <Cepheid> Er, lower-right corner, not upper-right. I forgot that the swapped bottom/top inverts things.
16:05 <ADragonDreaming> Warrior of Sunlight, Stabby McTaco
16:05 <Cepheid> Anyways, set the matrix to 0, 640, 480, 0, then 640,480 represents the lower-right. 320,240 represents the middle instead.
16:05 <Cepheid> This is irrespective of the actual screen size.
16:06 <Cepheid> If your screen size is 1024x768, and you use a 0,640,480,0 orthographic projection matrix, then 640,480 will represent the pixel at 1024,768.
16:06 <RazorSharpFang> As it happens, I'm using 960x540. :3
16:06 <Cepheid> Meanwhile, 320, 240 corresponds to 512/384.
16:07 <Cepheid> Basically, if you want flat, 2D, and coordinates to roughly correspond to pixel locations, you use an orthographic projection matrix the same size as the window/screen.
16:07 <RazorSharpFang> Ooh, this makes stretching-scaling the default if you let the window be resized.
16:08 <Cepheid> More or less.
16:08 <Cepheid> There's an easy way to handle 16:9 using a resolution-independent manner.
16:08 <Cepheid> IE: No matter the resolution, it'll always look the same, so long as it's a multiple of 16:9.
16:08 <Cepheid> Basically, use an orthographic projection matrix of 0,16,9,0
16:09 <Cepheid> You'll have to then specify coordinates in fractions of 16 and 9 instead
16:10 <Cepheid> As for sizing the window and using non-16:9 resolutions, that's a bit trickier.
16:10 <RazorSharpFang> I suppose letter-boxing would be difficult.
16:11 <Cepheid> Not super difficult, but it is a bit more complicated, yes.
16:13 <Cepheid> Let me figure it out, and I'll pastebin it. I need to do this code anyways.
16:14 <RazorSharpFang> Ah, resizing just has everything drawn in the bottom-left corner.
16:14 <Cepheid> Probably messes up the matrix stuff, I'm not sure how SDL handles it all.
16:18 <RazorSharpFang> Using SDL_GetTicks() I can see that my drawing is taking less than a millisecond to complete. :3
16:20 <RazorSharpFang> A whole four triangles.
16:20 <Cepheid> Throw the triangle drawing into a loop of 1000, or 10000.
16:21 <Cepheid> Should start seeing the time increase pretty quickly.

17:21 <Cepheid> There we go, figured out what I was doing wrong.
17:21 <Cepheid> RazorSharpFang: Depends on the shape.
17:22 <Cepheid> If you're talking curved lines, you can just use GL_LINES instead of triangles. If you want thicker lines, you can enable line smoothing, then specify the line thickness via glLineWidth(), but there are problems with that API.
17:23 <Cepheid> Namely, it's limited in how thick the lines can be, and the accuracy is limited.
17:23 <Cepheid> For example, on one card, line thicknesses might be limited to factors of 0.125.
17:23 <Cepheid> While on another, it's 0.250.
17:23 <Cepheid> Or some other weird fraction.
17:23 <RazorSharpFang> Let's suppose I'm only talking about solid shapes. I'd call these "Fills"
17:24 <Cepheid> So curved shapes.
17:25 <Cepheid> Like in modern vector graphics, such as SVG or flash stuff.
17:25 <Cepheid> Where you specify a shape using a bunch of "Paths", either straight or curved, and are then filled in based on the relevent data.
17:26 <RazorSharpFang> If the shape is "concave" (What does that mean if the shape is curved?) then you can draw a lot of triangles from the centre point. (Good luck figuring that out)
17:27 <RazorSharpFang> .... I'm starting to get the feeling that there's a lot of maths involved with graphical drawing.
17:28 <Cepheid> There is.
17:28 <Cepheid> Linear algebra, brush up on it.
17:29 <Cepheid> It gets trickier when you start dealing with self-intersection and such.
17:30 <RazorSharpFang> I suppose any non-concave (?) curved shape could be broken into multiple concave (?) shapes.
17:30 <Cepheid> Convex polygons are polygons with an interior angle that's greater than 180 degrees.
17:31 <Cepheid> ER, less than.
17:31 <Cepheid> Meanwhile, concave is greater than 180.
17:31 <RazorSharpFang> Right, but does that definition make sense for shapes with curved boundaries?

17:43 <RazorSharpFang> https://imgur.com/29pgOcy - A shape that has points within it that intersect with a line drawn from the perimetre to the centre.
17:43 <RazorSharpFang> A shape like that would be a problem for me.
17:45 <Cepheid> Mmm, that'll work, yeah.
17:46 <RazorSharpFang> The black dot being the "centre" of the shape.
17:46 <RazorSharpFang> But I don't know how to calculate the centre of an arbitrary polygon, or what the centre of an arbitrary polygon actually means.

17:54 <Cepheid> Can't help you there, I don't know the math for it.
17:55 <Cepheid> I don't deal with parametric curves.
17:55 <RazorSharpFang> I don't even know what that means. :3
17:56 <Cepheid> Bezier curves and such.
17:56 <RazorSharpFang> But I'd probably start by pulling apart the curves present in the raw shapes into discrete lines by a precision value anyhow.

18:00 <RazorSharpFang> Let's see... flash curves look like they're beziers...
18:02 <RazorSharpFang> Now I need to somehow open the flash swf file, and obtain the curve information...
18:03 <RazorSharpFang> First I'd have to uncompress it...
18:07 <RazorSharpFang> What I'm actually interested in is the shape data...
18:11 <RazorSharpFang> It's nice that the data appears to be byte-aligned.
18:13 <RazorSharpFang> It's also really nice that the spec for SWF files provided example implementations for parsing through bits of it.
18:16 <RazorSharpFang> I really need a hex editor/viewer. Is there one you'd recommend me, Cepheid ?
18:21 <Cepheid> Hex Workshop(Paid), HxD(Free last I checked)
18:25 <RazorSharpFang> Looks good.
18:26 <Cepheid> Right, got a method for calculating the correct glOrtho values for a given aspect ratio.

18:31 <Cepheid> It's a garbage method, honestly, but it works.
18:34 <RazorSharpFang> How many bits is a `size_t` ?
18:35 <Cepheid> https://en.cppreference.com/w/cpp/types/size_t
18:35 <Cepheid> Implementation defined, no definitive answer.
18:36 <RazorSharpFang> Hrmm.
18:37 <Cepheid> That page implies it's at least equal in size to the pointer type of the architecture.
18:37 <RazorSharpFang> Well, a char must be at least a byte, a short must be at least two bytes, and a long must be at least four bytes.
18:38 <Cepheid> Assuming that is dangerous.
18:38 <RazorSharpFang> Those are part of the C spec.
18:38 <Cepheid> https://en.wikipedia.org/wiki/64-bit_computing#64-bit_data_models
18:38 <Cepheid> At least, sure.
18:38 <RazorSharpFang> That's all I need. A guarantee of /at least/
18:38 <Cepheid> Fair enough.
18:39 <RazorSharpFang> It's annoying that I'm going to be working with values that are not byte aligned though.
18:39 <Cepheid> size_t, based on the above definition, is guaranteed to be equal to the size of a pointer.
18:40 <Cepheid> Because on a 64-bit machine, the maximum address is 0xFFFFFFFFFFFFFFFF. Heavens help you if you ever address that.
18:43 <Cepheid> Yeah, on my laptop under Linux, it's 8 bytes.
18:43 <RazorSharpFang> Why is my compiler warning me about fopen being insecure?
18:44 <Cepheid> That's Microsoft being stupid.
18:44 <Cepheid> They have their own methods that are "safe" for the OS.

18:56 <RazorSharpFang> I guess I'm making an SWF file parser now. :3
18:57 <MikeyPony> hmm?
18:58 <RazorSharpFang> Doing game-development... in a roundabout way.
19:02 <RazorSharpFang> It's going to be easier to do this if I don't compress the SWF files at export.
19:05 <RazorSharpFang> So far I'm grabbing the headers, checking the signature, reading the file version, and the filesize. :3
19:06 <RazorSharpFang> I need to read... five bits? Somehow???

19:12 * Cepheid wanders off to take a shower.
19:13 <RazorSharpFang> I hate values that are less than a byte, or less than full bytes.
19:13 <Cepheid> RazorSharpFang: & operator, and bit shifting.
19:13 <RazorSharpFang> I still hate it though.
19:14 <Cepheid> Say you have a bit in location 9 of a 16-bit integer. ((IntegerVar >> 8) & 0x01)
19:14 <Cepheid> Anyways, shower.
19:14 <RazorSharpFang> I'm confused if I need the big endian end or the small endian end.
19:14 *** Parts: MikeyPony (MikeyPony@Pony-27t.7v4.205.213.IP) ()
19:16 <RazorSharpFang> I think it's little endian.

19:48 <RazorSharpFang> I hate SWF files already.
20:15 <Cepheid> Heh.
20:15 <Cepheid> Razor, why SWF files? Because an editor exists for tweening and such already for it?
20:18 <Cepheid> Because if you're looking for a way to load vector graphics akin to Flash, but don't need any of the programming, or special animation effects(*YET*), you might fare better parsing SVG.
20:24 <RazorSharpFang> Well, I can animate in flash, but I don't know SVGs, and I know flash can't export to SVGs.
20:26 <Cepheid> SVGs can be animated, last I checked. Not as well as flash, I don't think, but yeah, fair enough.
