After reading a lot, I'm about to use msdf (distance field) based billboards. I wonder how to render this most efficiently. I think instanced geometry won't do, as the geometry nad texture is actually different for every label.[17:42:13] <kernelpanic> Should I create one VBO with those 1000 labels? As you can see, I'm still somewhat lost, and would appreciate some guidance[17:42:14] *** john51 <john51!~john@15255.s.t4vps.eu> has joined ##OpenGL[17:43:32] *** Gama11_ <Gama11_!~quassel@pD9F99372.dip0.t-ipconnect.de> has quit IRC (Ping timeout: 240 seconds)[17:45:43] *** Ipe_ <Ipe_!~Ipe@a91-156-244-1.elisa-laajakaista.fi> has quit IRC (Quit: Konversation terminated!)[17:47:10] *** rawrawrer <rawrawrer!~rawrawrer@c58-111-144-57.thorn2.nsw.optusnet.com.au> has quit IRC (Quit: rawrawrer)[17:48:53] <Xeek> sounds reasonable to me[17:50:19] <derhass> It is probably best to stuff all of the labels into one texture object, like an array texture[17:50:31] <derhass> and do just one draw call for all of them[17:53:18] <derhass> also note that you don't necessarily need to store the full data for all 4 vertices. you could probably get away with 2d position + 2d size (a vec4) + some texture index[17:53:36] <derhass> and you could use such a buffer without instancing, and without a geometry shader[17:53:56] <derhass> just by using gl_VertexID[17:54:27] <anli_> I want to have a border with rounded corners around my extra viewport, do I have to create some kind of mask?[17:54:33] <anli_> Or do I have to render to texture?[17:54:43] *** karab44 <karab44!~karab44@unaffiliated/karab44> has joined ##OpenGL[17:54:59] <derhass> anli_: the stencil buffer might be the way to go[17:55:08] <anli_> ok...[17:55:11] <derhass> anli_: especially if you can reuse the same mask for many frames[17:55:23] <anli_> yes[17:56:54] <anli_> To draw the border around it, it is easiest to do that before I have set the viewport, I assume[17:57:02] <anli_> (and also before I have set the mask=[17:58:09] <derhass> well, you have two things here: drawing the border, and masking the rendering for the second viewport[17:58:16] <anli_> yeah[17:58:29] <derhass> stencil is only for the latter[17:58:38] <anli_> yeah[17:58:41] <derhass> you will need something to draw the actual border[17:58:53] <anli_> should I set the perspective matrix separately just for drawing 2d, like borders, text etc?[17:59:07] <derhass> that's up to you[17:59:14] <derhass> but I wouldn't use perspective at all for thatr[17:59:17] <derhass> *that[17:59:26] <anli_> nope, ortho would do[17:59:45] <derhass> I probably would not use a matrix at all, and direclty work in NDC[17:59:52] <derhass> but this of course depends[18:00:08] <anli_> What is NDC then? :)[18:00:54] <anli_> And how do I output text in an effective way?[18:01:05] <anli_> Overlaying my canvas with divs maybe :)[18:01:54] <Xeek> canvas, divs, sounds like html[18:01:56] <derhass> well, for drawing text with the GL, usually a texture-based approach is used[18:02:27] <derhass> but a real text rendering subsystem will require some effort[18:02:49] <anli_> It must be a pita to output text with textures[18:02:59] <anli_> And it will probably make an ugly result as well? :)[18:03:09] <Xeek> only if yo8u scale it and not use distance fields[18:03:27] <anli_> distance fields as in char widths?[18:03:32] <Xeek> no[18:03:39] *** sandeepkr <sandeepkr!~sandeepkr@111.235.65.5> has quit IRC (Read error: Connection reset by peer)[18:04:18] <derhass> anli_: signed distance fields are a nice way to draw text even when scaled[18:04:26] *** sandeepkr_ <sandeepkr_!~sandeepkr@111.235.65.5> has joined ##OpenGL[18:04:27] *** DrBenway <DrBenway!~DrBenway@190.18.153.73> has joined ##OpenGL[18:04:53] <Xeek> http://imgur.com/a/U2wQc <- signed distance field charcters, good for scaling but not if you intend to draw small text - then just plain bitmap fonts will do and look fine[18:08:06] *** ville <ville!~ville@176-93-81-184.bb.dnainternet.fi> has joined ##OpenGL[18:08:07] <anli_> Will it perform good to create text with GL_TRIANGLE?[18:08:28] <anli_> Maybe such chars should be "cached" into textures :)[18:08:30] <Xeek> each charcter is a triangle yes, that much is obvious[18:08:36] <Xeek> rather, 2 triangles[18:08:49] <anli_> yes, but a char could also be made out of triangles[18:08:51] <derhass> I think anli means using geometry to form the glyphs itself[18:08:51] <Xeek> well yeah, if they're not textures you can't really display them[18:08:55] <anli_> yeah[18:09:09] <anli_> derhass++[18:09:24] <Xeek> derhass: everything is pretty much triangle based.
