20150415 12:20:33 <zubzub_> hmmm
20150415 12:20:40 <zubzub_> newt does not seem to support touch input
20150415 12:20:57 <zubzub_> only as mouse input
20150415 12:21:02 <zubzub_> but mouse != touch
20150415 12:35:34 <zubzub_> 22:54 < Eclesia> dirtytrixzzster: what have you made which could be interesting ?
20150415 12:35:39 <zubzub_> the one thing
20150415 12:35:45 <zubzub_> that I have never ever seen so far
20150415 12:35:47 <zubzub_> in any game
20150415 12:36:03 <zubzub_> is proper water collission with a shore/rock/whatever
20150415 12:36:29 <zubzub_> it's always straight lines (intersection fo water with some object)
20150415 12:37:58 <zubzub_> which totally kills the nice water effects like reflection, ripples at whatnot
20150415 12:38:51 <zubzub_> "ooh look what a nice pool"
20150415 12:38:56 <zubzub_> "too bad it's shaped like a hexagon"

20150415 13:09:07 <gouessej> Hi
20150415 13:09:38 <gouessej> zubzub: Which OS do you use? Touch input is supported only under Android in NEWT, isn't it?
20150415 13:12:07 * gouessej (5ee4b442@anon) Quit (Client Quit)
20150415 13:23:24 <zubzub> linux
20150415 13:23:31 <zubzub> I would like to use libinput
20150415 13:23:38 <zubzub> for my custom newt backend
20150415 13:24:00 <zubzub> thing is that newt makes no differentiation between mouse or touch
20150415 13:25:37 <eclesia> zubzub: when you will have the nice water effect, I'll gladly accept it in the project

20150415 14:05:27 <gouessej> zubzub: The pointer type allows to make a distinction between mouse and touch input

20150415 14:07:16 <zubzub> oic
20150415 14:07:21 <zubzub> ok cool :)
20150415 14:08:34 <zubzub> once I get egl kms with libinput implemented in newt, I'll see if I can get something wayland related implemented
20150415 14:08:58 <zubzub> they'll most likely live as seperate newt drivers as they depend on jna
20150415 14:24:37 <zubzub> I'm surprised nobody else implemented egl kms for jogl
20150415 14:24:43 <zubzub> it seems so trivial
20150415 14:24:51 <zubzub> and perfect use case for embedded/kiosk stuff
20150415 14:25:39 <zubzub> it's basically the same ad the rpi back-end, just slightly different setup of the egldisplay and egl surface
20150415 15:00:38 <bruce-> eclesia: in a good radial blur you should not be able to see the individual steps
20150415 15:01:04 <bruce-> eclesia: is this with ping-ponging between two buffers?
20150415 15:01:17 <eclesia> number of sampling steps can be increased
20150415 15:02:38 <bruce-> the trick is to perform radial blur with read from buffer A, write to buffer B, then from B to A, this doubles the amount of steps performed in each iteration
20150415 15:02:47 <eclesia> ping-ponging ? it's a post process , with one texture as input that's all
20150415 15:03:54 <eclesia> why not just increase the number of steps and do it in one pass then ?
20150415 15:05:17 <bruce-> because you need way more texture reads
20150415 15:18:59 <rmk0> they call it a "separable blur": http://sunsetlakesoftware.com/2013/10/21/optimizing-gaussian-blurs-mobile-gpu
20150415 15:19:11 <rmk0> i do the horizontal and vertical passes separately in my own renderer
20150415 15:21:06 <eclesia> I have that for gaussian blur, but for radial that's ... different
20150415 15:21:38 <rmk0> oh... missed the "radial" part
20150415 15:21:41 <rmk0> \o\

20150415 18:08:38 <zubzub> Eclesia: well that's another way of solving it
20150415 18:09:04 <zubzub> looks like the make the entire water surface '3d'
20150415 18:09:22 <zubzub> most games these days just apply some nice texture and reflection on a 2d water surface
20150415 18:09:32 <zubzub> which is ok for me
20150415 18:09:44 <zubzub> except that this 2d surface collides with the shore in a straight line
20150415 18:10:20 <zubzub> so if they could fix that straight line so as it looks like the water is going up and down, then that would fix my 'problem'

20150415 19:40:36 <zubzub> sgothel: why does the rpi newt display driver first creates a 'fake' graphics device (a 'default' one)
20150415 19:40:47 <zubzub> and only goes on creating the real one when a window is created?
20150415 19:40:58 <zubzub> seperately
20150415 19:41:29 <sgothel> (back from the lot :) ..
20150415 19:41:34 <sgothel> err ..
20150415 19:42:06 <sgothel> probably b/c we create native resources lazily ..
20150415 19:42:16 <sgothel> so the native device is an EGL display device
20150415 19:42:28 <sgothel> but would need to check code ..
20150415 19:42:42 <sgothel> I glanced over discussion above .. (EGL/JNA ..)
20150415 19:42:51 <sgothel> why not creating the binding w/ GlueGen?
20150415 19:43:10 <sgothel> it shall be fit enough to digest vanilla headers
20150415 19:43:11 <zubzub> because I'm more familiar with jna :p
20150415 19:43:30 <zubzub> I'm mostly still in the poc phase
20150415 19:43:34 <sgothel> then - I have to re-do the work w/ GlueGen :-/
20150415 19:43:39 <zubzub> yeah
20150415 19:43:40 <zubzub> sorry :p
20150415 19:43:44 <sgothel> well
20150415 19:44:03 <sgothel> probably possible to have your interface definitions .. and their usage as a template
20150415 19:44:21 <sgothel> and create GlueGen'ed impl. matching it .. almost
20150415 19:44:34 <zubzub> well it's actually very simple
20150415 19:44:47 <zubzub> the whole kms drm stuff
20150415 19:44:50 <sgothel> if you have test code for your wayland binding .. and the binding .. I can use that
20150415 19:45:01 <sgothel> kms (kernel mode setting) ?
20150415 19:45:03 <zubzub> I have a client example
20150415 19:45:12 <zubzub> yes
20150415 19:45:32 <zubzub> http://virtuousgeek.org/blog/index.php/jbarnes/2011/10/31/writing_stanalone_programs_with_egl_and_
20150415 19:45:46 <sgothel> so: kms + EGL/kms ?
20150415 19:45:52 <zubzub> yes
20150415 19:46:05 <sgothel> i.e. EGL Native<Type> for kms .. nice
20150415 19:46:12 <sgothel> all fullscreen then, I assume
20150415 19:46:20 <zubzub> basically a generic egl setup for all drivers that support kms
20150415 19:46:21 <zubzub> yeah
20150415 19:46:36 <sgothel> yes, a simple binding like Android, RPI, or the other one .. K?
20150415 19:46:53 <sgothel> (i.e. all EGL based)
20150415 19:47:13 <zubzub> well android and dispman don't support kms iirc
20150415 19:47:25 <zubzub> a whole lot of other drivers do though
20150415 19:47:31 <sgothel> no, I mean the native display device handles are EGL
20150415 19:47:58 <zubzub> yeah
20150415 19:48:09 <zubzub> but what is your question?
20150415 19:48:31 <sgothel> .. just creating a mindmap / big-picture ..
20150415 19:48:48 <sgothel> are those things available in parallel .. or either-or
20150415 19:48:59 <sgothel> i.e. X11/EGL, KMS/EGL, .. etc etc
20150415 19:49:07 <zubzub> xor
20150415 19:49:14 <sgothel> if exclusive .. then fine, good
20150415 19:49:37 <zubzub> you basically take exclusive ownership of the graphics card afaik
20150415 19:49:37 <sgothel> jogamp.newt.driver.kd <- the other pure EGL thingy
20150415 19:49:47 <sgothel> ay
20150415 19:50:13 <sgothel> would be great if you can track this w/ bug reports
20150415 19:50:26 <sgothel> and add links to your resources (code, tests)
20150415 19:50:57 <zubzub> well I'm not sure how I can unit test a kms/egl newt driver setup
20150415 19:50:58 <sgothel> my schedule: Now - April 28th: renovations; April 28th: Moving
20150415 19:51:04 <zubzub> but the kms/egl newt driver is pretty stand alone
20150415 19:51:10 <zubzub> if I get it finished
20150415 19:51:16 <sgothel> April 29th ... setup .. (maybe loss of internet for a few days ..
20150415 19:51:17 <zubzub> so I can create a bug and link the source
20150415 19:51:24 <sgothel> back in a bit .. dinner, laters
20150415 19:51:27 <zubzub> bye
20150415 20:02:17 <zubzub> sgothel: the kd driver does not seem to be included in 2.3.1 (?)
20150415 20:02:22 <zubzub> on maven

20150416 00:16:53 <badshah400> Hello helpful jogamp devs! I would be much obliged if someone could help me bring scirenderer up to scratch for use with jogl 2.3.x (I am trying to fix http://forge.scilab.org/index.php/p/scirenderer/issues/1545/ where the use of old deprecated symbols shows up)
20150416 00:17:44 <badshah400> I am not a scilab/scirenderer dev, but I package scilab for openSUSE, and since upstream seems not too active, I might have to fix this myself
20150416 00:19:03 <badshah400> If there is any guide on how to port e.g., com.jogamp.opengl.util.awt.Screenshot and com.jogamp.opengl.GLPbuffer to new jogl, that would be of significant help. Thanks!
20150416 00:19:11 <sgothel> GLPbuffer has been removed, use an offscreen GLAutoDrawable ..
20150416 00:19:30 <sgothel> let me find the git commit
20150416 00:19:56 <sgothel> jogl ec2d94ca26ddab8ec67135ebc5f2d0a43f6a4c25

20150416 00:21:41 <sgothel> ^^ how to replace GLPbuffer w/ GLAutoDrawable
20150416 00:22:29 <sgothel> and Screenshot w/ AWTGLReadBufferUtil
20150416 00:23:20 <sgothel> should fix all your issues
20150416 00:44:52 <badshah400> sgothel: thank you very much, I will ping you back if I face difficulties, but this is a big help
20150416 01:39:51 * phao (~phao@anon) has joined #jogamp
20150416 02:55:42 <badshah400> sgothel: if you are still around, I think I am almost there with the fixes. there is this one problem still lingering: the use of GLAutoDrawable.getWidth()
20150416 02:56:05 <sgothel> -> getSurfaceWidth()
20150416 02:56:07 <badshah400> Should I replace it with GLAutoDrawable.getSurfaceWidth() and so on for getHeight() too?
20150416 02:56:11 <sgothel> :)
20150416 02:56:14 <badshah400> sgothel: ah, thanks
20150416 02:56:28 <sgothel> this is Hi-DPI related ..
20150416 02:57:02 <badshah400> sgothel: kind of fig it out from the extensive javadoc at jogamp's site (comparing v2.0.2 to v2.3.1)
20150416 02:57:35 <sgothel> great (at least somebody is reading it :)
20150416 02:59:05 <badshah400> sgothel: yes, thanks a lot for such extensive documentation, really useful
20150416 03:05:01 <sgothel> can you push your changes upstream to Scilab ?
20150416 03:13:46 <badshah400> sgothel: I will attach it in the bug report, but I don't have commit rights, so someone will have to review and push it himself/herself, which is good I think to get a review
20150416 03:26:57 <badshah400> sgothel: here goes: http://forge.scilab.org/index.php/p/scirenderer/issues/view/attachment/313/0001-Port-to-jogl-2.3.patch
20150416 03:28:04 <badshah400> finally got it building, thanks to a bunch of help from you
20150416 03:28:25 <sgothel> you are vert welcome
20150416 03:28:29 <sgothel> *very* :)
