[07:25:42] <Dom_> I have two uniforms for the x and y offset for my uvs to animate sprites on a sprite sheet
[07:26:12] <Dom_> it seems that setting them for one sprite sets them for all other sprites using the same shader
[07:26:32] <Dom_> despite me setting the offset to 0 if no offset is used
[07:26:49] <Dom_> on ios simulator with es2
[07:27:01] <Dom_> would this be a driver optimization / bug?
[07:27:39] <Dom_> other uniforms work as expected

[07:31:03] <Dom_> my uniform map thing thought my default (setting the uniform back to 0) was a double
[07:31:10] *** Alina-malina has joined ##OpenGL
[07:31:17] <Dom_> so obvioudly it wasn't being set
[07:33:14] * dahlia uses a 3x3 matrix so textures can be translated/rotated/scaled
[07:33:49] * Dom_ is talking about uv not rans rot scale changes which are done with a model matrix
[07:34:05] * dahlia is too
[07:34:58] <dahlia> its not something I invented... even fixed function GL has a texture matrix

[08:09:17] <Dom_> hmmmm
[08:10:03] <Dom_> i have an issue where the frame counter is going up by how many references there are to each sprite in the scene since a node only holds a pointer to sprite
[08:10:23] <Dom_> and the sprite is in charge of its own animation frame count
[08:10:51] <Dom_> thus the incrementor gets called x amount of times per draw

[10:00:29] <bakibour> I have some problems clearing a FBO on ATI and INTEL boards. On the NV board it just works fine.
[10:00:52] <bakibour> Is there anything more than doing a glbindframebuffer and glclear i should have to do for this on all platforms?
[10:01:51] <slime> make sure the buffers you want cleared are all active (i.e. glDrawBuffer / glDrawBuffers)
[10:02:25] *** james4k has quit IRC
[10:02:27] <bakibour> Hm ok, ill do that dug up some post that said it was not required but ill check that out.
[10:02:55] <slime> it's only needed if the buffers you want cleared aren't active in that FBO
[10:03:02] <slime> or you could use glClearBuffer
[10:03:25] <bakibour> Ah thanks i think i will try that one first.

[12:39:24] <bakibour> Ah ok
[12:39:52] *** sam has quit IRC
[12:40:02] <bakibour> This clear problem is pretty strange. Is it in general a better idea to clear the FBOs with glClearBuffer or glClear?
[12:40:47] <Hunts> what problem?
[12:41:45] <bakibour> I have a FBO one texture, i clear it using glClear after glBindFramebuffer and glDrawBuffers etc. Works perfectly fine on the Nvidia board in my laptop, but does not on the Intel board.
[12:42:18] <Hunts> well glClearBuffer is usually used for buffers with integer format
[12:42:18] <bakibour> Then i tried glClearBuffers cause someone mentioned it, which again works on Nv but not on Intel.
[12:42:20] *** Darkchaos has joined ##OpenGL
[12:42:32] <bakibour> But there is also a fp version.
[12:43:01] <Hunts> yeah
[12:43:12] <Hunts> but glClear uses glClearColor which is only fp
[12:43:18] <Hunts> that's why glClearBuffer was introduced
[12:43:23] <bakibour> Ah ok
[12:43:40] *** cr`nge has joined ##OpenGL
[12:43:45] <bakibour> How can you see stuff like this?
[12:43:58] <Hunts> see?
[12:44:14] <bakibour> Or know
[12:44:27] <bakibour> How would i be able to aquire knowledge like that
[12:44:31] *** adsc has joined ##OpenGL
[12:44:40] <Hunts> its history
[12:44:46] <Hunts> for me it was pretty obvious
[12:44:47] <Darkchaos> Hello Guys. I have some graphical bugs in my Android App "Speed Ping-Pong". Would somebody mind installing it and take a guess on what it might be? I already tried using different z-values (against z-buffer-fighting) however that did not change anything. (maybe the z values are still too close). It also seems to be the worse the less power is available
[12:46:03] <Bloodust> Darkchaos video
[12:46:03] <bakibour> So glClearBuffer just gives me overall better access to how to clear what in the buffer but also is as fast
[12:46:07] *** charlie5 has quit IRC
[12:47:08] <Hunts> bakibour: yeah
[12:47:41] <bakibour> Somehow i have the feeling that the clearing problem is also due to rendering objects.
[12:48:01] <bakibour> If i render an object in the buffer also it is clear properly.
[12:48:35] <bakibour> Maybe i need to unbind stuff earlier or so?
[12:49:09] <Hunts> uhm what?
[12:49:29] <bakibour> Unbind the FBO so it can be rendered to / cleared.
[12:49:46] *** kuldeepdhaka has quit IRC
[12:49:51] <bakibour> Clearing alone does not work but clearing and then rendering works.
[12:50:04] <Hunts> no, just clearing works
[12:50:11] <Hunts> how are you going to render to the FBO if its not bound? :)
[12:50:26] <bakibour> Meh true...
[12:50:43] <bakibour> What other reason might be the cause?
[12:50:53] <Darkchaos> Bloodust: I'll to this evening, problem is I'll have to go soon and need some other phone to film it because I have no screen capturing tool :/
[12:50:54] <Hunts> driver bug
[12:51:00] <bakibour> I installed the INDE Trial version ill try that out.
[12:51:01] <Hunts> bakibour: you should pastebin code
[12:51:35] <bakibour> Hunts: I can't its company code. But i might try to whip some test application app up to test the problem there.
[12:51:50] <Bloodust> haah
[12:52:25] <bakibour> I think that it does not work on ATI boards also.
[12:52:31] <Hunts> bakibour: yeah a test case would be nice
[12:52:45] *** centrinia has joined ##OpenGL
[12:52:49] <bakibour> So i thought it might be some thing i do "wrong" with the standard stuff.
[12:53:12] <bakibour> Nv is just easier going on some parameter i set or so.
[12:53:54] <Hunts> bakibour: very hard to say without seeing code
[12:54:32] <bakibour> Yep ill try to set something up, after i have added all the ClearBuffer stuff to the code base.
[12:54:54] <mathias__> bakibour: Did you try a opengl debugger?
[12:55:04] <bakibour> As i said i just installed INDE
[12:55:24] <bakibour> I need to get used to it though, have not used it yet.
[12:57:37] <bakibour> Is there maybe some kind of "optimization" that allows for skipping Clears if nothing is rendered to the target?

[14:46:29] <delicado> hi sorry if this is off-topic but i don't know where to ask and since this is graphics related too (##math people did not help me). would adding multiplying quaternions add up its rotation? say i have Q1 with 30 degrees in Y axis and Q2 with 30 degrees in Y axis. will the result of "Q1 * Q2" be 60 degrees in Y axis?
[14:46:51] <delicado> i mean multiplying not "adding multiplying"
[14:48:54] *** shingshang has joined ##OpenGL
[14:49:14] <Hunts> delicado: yeah, AFAIK they work like that
[14:50:04] *** DrSkyLizard has joined ##OpenGL
[14:50:39] <ClaudiusMaximus> delicado: multiplying quaternions is composing rotations, composing a rotation with itself (like your example) doubles the angle. note that in general it is not commutative (q1 * q2 /= q2 * q1)

[14:58:22] <_Cid> if I were to delete a texture by calling delete right after glTextImage2D or something

[14:58:47] <_Cid> mmmmmm quats
[14:59:00] <Hunts> _Cid: uhm, no?
[14:59:28] <enleeten> opengl drivers are kind of a black box
[14:59:29] <_Cid> does that not copy it into the texture buffer
[14:59:32] <_Cid> perhaps not vram
[14:59:33] <Bloodust> probably same semantics as on cpu side
[14:59:35] <enleeten> you give it suggestions
[14:59:44] <enleeten> but it does what it wants :)
[14:59:50] <Hunts> _Cid: but you don't have access to it
[15:00:10] <_Cid> I mean the last parameter of glTexImage2D
[15:00:16] <_Cid> if I were to delete that buffer
[15:00:25] <Hunts> ah
[15:00:26] <Hunts> then yes
[15:00:27] <_Cid> this is more hypothetical
[15:00:30] <Hunts> you said delete the texture :)
[15:00:32] <Bloodust> yeah you can delete it right away
[15:00:33] <Hunts> not the pixel data in the CPU side
[15:00:35] <Hunts> ;)
[15:00:36] <_Cid> ah
[15:00:37] <_Cid> sorry
[15:00:49] <_Cid> yeah so it would persist there
[15:00:51] <Bloodust> the call blocks until the mem has been copied
[15:01:00] <_Cid> yeah

[19:54:22] <roxlu> hi guys, I’m reading up on feedback transforms and reading this page https://open.gl/feedback and in some other articles I see they use glGenTransformFeedbacks(), but not in the linked one. Is this a mistake on that page?

[20:05:29] <harha_> I think I finally got my Cook-Torrance shader to work. :) I had some weird artifacts in the output before and viewDir was calculated correctly but now it really looks good and correct IMO.

[20:06:32] *** SHLV has quit IRC
[20:07:00] <harha_> * viewDir wasn't calculated correctly. Now I'm calculating it by taking the current vertex coordinate, negating and normalizing it. Is that correct?

[20:08:03] <harha_> There's a video, looks correct enough to me now.
[20:15:11] *** slidercrank has joined ##OpenGL
[20:16:45] <XMPPwocky> okay, i am writing a semi-generic renderer and am wrangling materials around. there are various shaders in play, and one issue is uniforms
[20:17:24] *** Khlorghaal has quit IRC
[20:17:29] <XMPPwocky> i am thinking about having a few standard uniform blocks, with fixed bindings (specified in the shader)
[20:18:10] <XMPPwocky> er, not fixed bindings, soryr
[20:18:57] <XMPPwocky> then, for example, i'd have a UBO with a transform matrix. the renderer would update the UBO with the MVP matrix of whatever it's drawing
[20:19:56] *** sasoo7_ has joined ##OpenGL
[20:21:00] <XMPPwocky> in the vertex shader it'd have a uniform block, for that transform matrix, and when we loaded the shader we did glUniformBlockBinding(program, glGetUniformBlockIndex(program, "transform"),
[20:22:06] <XMPPwocky> 42); for example. So then during rendering we just call glBindBufferRange(GL_UNIFORM_BUFFER, 42, ...)
[20:22:06] *** sasoo7_ has quit IRC
[20:24:15] *** Lucretia has quit IRC
[20:24:29] <XMPPwocky> is this a reasonable thing to be doing? this way i don't have to maintain a mapping of uniforms to uniform locations in the shader, and I don't have to keep calling glUniform... every time we want to render something
[20:24:33] <XMPPwocky> we would just work with the buffer instead

[20:55:24] <slimsag> GL_MAX_TEXTURE_SIZE - "The value gives a rough estimate of the largest texture that the GL can handle. The value must be at least 1024."
[20:55:35] <slimsag> So, say I have 4096 as the value
[20:55:46] <slimsag> I can have a 4096x4096 texture, sure
[20:55:59] *** james4k has quit IRC
[20:56:33] <slimsag> can the dimensions go past that if I subtract from the other? I.e. can I have a 2048x6144 texture?
[20:56:49] <slime> no
[20:57:03] <slime> it's the maximum amount of any dimension (in a 2D texture)
[20:57:04] <slimsag> slime: ok, so it's a upper limit on the actual dimensions
[20:57:40] <slimsag> so for a sprite sheet it would be better to make it square, yeah?
[20:57:56] <slimsag> (if you had to use a massive texture)
[20:58:48] *** sasoo7 has quit IRC
[20:58:48] <slime> best to make it use the least amount of size while accounting for the maximum width/height on the target min-spec GPU
[20:59:04] *** sasoo7 has joined ##OpenGL
[20:59:17] <roxlu> ping glYoda
[20:59:23] <slimsag> slime: okay, that's what I thought. THanks a ton for the confirmation!

[22:06:21] <Guest93506> Could someone take a look at this code and see if my approach for a shader compiler is right? http://pastebin.com/ZShgBynN
[22:06:21] *** Lemml has quit IRC
[22:07:05] *** Kane has quit IRC
[22:07:06] *** pazul has joined ##OpenGL
[22:07:07] <Bloodust> I can tell you right now that your C++ approach to shader loading is not right
[22:07:30] <Guest93506> okay, whys that?
[22:08:03] <Bloodust> 1) function parameters are const but not const reference
[22:08:45] <Bloodust> 2) 'new' calls in lines 3 and 4 are unnecessary and not good coding style
[22:09:23] <Bloodust> 3) line 15. theres no need to use new, std::ifstream shaderFile(vertex); is enough
[22:10:05] *** foreignFunction has quit IRC
[22:10:27] <Bloodust> 4) the whole while loop that is supposed to read the file is broken, it just doesnt make sense
[22:10:53] <Bloodust> other than that the c++ is fine'ish
[22:11:15] <Bloodust> yeah other than the c++ is fine
[22:11:32] <Bloodust> now the opengl part
[22:11:41] <Guest93506> okay thank you

[22:13:04] *** fmardini has quit IRC
[22:13:31] <Bloodust> the gl part looks alright
[22:13:35] <Bloodust> I dont see any major problems
[22:14:00] <Guest93506> okay, but about the loop, it reads my files as supposed
[22:14:02] <Bloodust> although you dont check compile status for the fragment shader
[22:14:19] *** ManDay has quit IRC
[22:14:34] <Bloodust> well the loop reads the file but it doesnt actually store the result anywhere
[22:14:41] <Bloodust> unless you file is just 1 line
[22:15:12] <Bloodust> also line 24. ifstream::close is superfluous
[22:15:27] <Bloodust> the stream is closed automatically in ifstream destructor
[22:15:53] <roxlu> Guest93506: on line 28 you handle the case where you can’t open the file, but you don’t return there and continue. I would cleanup there and return
[22:16:25] <Guest93506> oh yeah, youre right
[22:16:39] <Bloodust> and print the file names too
[22:16:48] <roxlu> If you don’t use ‘new’ you don’t need to delete everything when you return btw
[22:16:55] <Bloodust> if you have 10 shader files and they all say "could not open", its not very helpful
[22:17:14] <Guest93506> yes
[22:17:22] <roxlu> Anyone experience with transform feedbacks?
[22:18:52] <roxlu> (e.g. I’m wondering why some posts describe the use of glGenTransformFeedbacks() and some other don’t even use this… I tested with a basic implementation and it actually seems to work for this simple case)

[23:05:49] <nitroxis> What would be the glBlendFunc for multiplicative blending with transparency?
[23:07:01] <nitroxis> i.e. multiplicate is glBlendFunc(GL_DST_COLOR, GL_ZERO), but if my source has for example 0.5 alpha, I want it to not fully multiply the two colors, only 50%
[23:07:42] <nitroxis> like if you have a multiplicative layer in Gimp and change the opacity of that layer
[23:08:20] *** razieliyo has quit IRC
[23:09:27] <slimsag> nitroxis: not sure, but this might help: http://www.andersriggelsen.dk/glblendfunc.php

[23:11:25] <slimsag> nitroxis: google also turns up promising results when searching for "opengl photoshop blend modes"

[23:37:05] <ra4king> Hello!
[23:37:15] <ra4king> What exactly is this GLSync object?
[23:38:02] <foobaz> it is like glFinish but faster
[23:38:32] <foobaz> it is for when you need to wait for an operation to complete before doing another operation, and you have some other work you can do while you're waiting for the first one
[23:38:49] *** prophile has quit IRC
[23:38:53] <foobaz> for example you might render into a texture and then you want to use that texture
[23:39:19] <foobaz> but you have to wait for opengl to finish rendering the texture, and while you're waiting you might render a different texture
[23:39:33] *** Guest45612 has quit IRC
[23:40:33] *** delicado2 has quit IRC
[23:40:35] *** Guest45612 has joined ##OpenGL
[23:42:18] <foobaz> the glsync splits up the glfinish into two parts, first you create the sync object, then later you wait on the sync object
[23:42:52] <foobaz> so you don't have to wait for the whole gl buffer to complete, you only have to wait for it to get up to the sync point you inserted earlier
