Currently I am simply loading 2 times the same image and processing the barrel distortions on each half of the image, left and right.

Re: [PD] [GEM-dev] Oculus Rift distortion/support
hello Michael, i copy this mail to pd list, since it is of generic interest. but first : did anyone have a working example of oculus rift in GEM? Rendering on stereo is a nice idea, but as you noticed, in order to sumarized all the object it's easier to render in a framebuffer then distord this resulting image. Ideally, you would use stereo parametter to render in a framebuffer, then render the framebuffer through a shader in the main windows (whitout stereo). but i dont thing you can do that in Gem. Here is how i would do it. 2 framebuffer, and an abstraction that render primitive in the 2 framebuffer. then render this 2 framebuffer in the main windows with a shader, or merge this 2 FB in a 3d one and render this last FB with the shader. some things need to be adjusted (angle of view of the virtual cam / eyes distance /framebuffer size, etc). and the shader has to be added...

However, now I know how to use shaders in Gem and on my Windows OS and I already played around with simple barrrel distortion examples... Thank you again for your previous support!! You proposed a solution (your Email below) how to implement the barrel distortion to our virtual world: /1st : left eye view without distortion, rendered in a frame buffer // //2nd : right eye view (no distortion / framebuffer) // //3rd : using the 2 previous texture and a shader, render the final image/ I'm still having some questions: 1.) Our current world is using the gemwin stereo parameter to create 2 images (- actually it is one Gem window, but we adjusted resolution and size to fit it to our old HMD and each eye can see only half of the image; see attachement). I'm wondering if it possible to use just ONE shader to render the entire image in one step?? But I'm not sure if this is possible with texturing?? If not: Will I still be able to use the stereo parameter in gemwin?? 2.) As you can see in my screenshot: our world consists of many objects (cubes, lines, fadecrosses, spheres, ...). How can I summarize those objects, before processing them? Do I need to use a gemframebuffer for every single object?? My plan is to finish in 1(-2) months.

[PD] declare and abstraction
Hello, I'm trying to setup a project organised in folder like this : projet/ dir1/ abstraction1/ foo patch1.pd dir2/ abstraction2 bar patch2.pd patch.pd in patch1.pd, i've got a declare -path abstraction1 so that i can use the foo abstraction same in patch2 : declare -path abstraction2 to use the bar abstraction patch1 and patch2 are autonomous. now, in patch.pd, I want to use patch1 and patch2. when using declare -path dir1, I can use patch1, but the declare in patch1 is relative to the projet directory, not to the dir1, so foo is not found. when using dir2/patch2, it's the same problem. i would like that patch1 and patch2 deal with the declaration of path for abstraction there are using. And i would like to be able to use patch1 and patch2 in patch, without having to add declaration. i know that there is a warning in declare help not to do that. so, what is the vanilla way to organised project like that? for now, the solution i found is to organised things like this : projet/ dir1/ abstraction1/ foo patch1.pd dir2/ abstraction2 bar patch2.pd all/ patch.pd and using declare -path ../patch1/abstraction1 in patch1. but i don't really like that. thanks cheers Cyrille ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Re: [PD] need help with gem and glsl feedback
hello,
i think there is a game of life example in gem example/glsl folder.
this example show how to make a simple feedback.
you dont need to modifie the rendering, since you juste nead a redback after
the rendering.
but readback are ineficient.
example 07.framebuffer_and_shader show how to use 2 framebufer in order to use
1 to render the 2nd one.
this can be use to do efficient motion blur, or whatever shader you want.
but you have to modifie the rendering part : replacing gemhead by abstraction
that render in the same framebufer.

I will need a linear equation conversion. As I wrote in last mail, I was needing something like this, first in ActionScript... then in Python... but I never could did it. Now, I needed again in Pd... so, I made lin-eq-conv.pd with extrapolation and lin-eq-conv-clip.pd for clipped values. I made it as neat as I could, to see how it works. Using x0-x1 and y0-y1, it uses expr to get a and b at load. Then, it only computes aX + b = Y. I attach the lin-eq-conv.pd, lin-eq-conv-clip.pd and lin-eq-conv-help.pd. i don't see where Iohannes was wrong : it's easy math, and you made the abstraction. ;-) Also, I have some issues using [autoscale]. I start giving values and it outputs only 1. Then, I start to down the input and, then, it shows the real output. Maybe it's about this version (0.43.4 Pd-Extended 64bits). that's the desired autoscale behaviors. it scann input and scale it acording to it's min and max value. see help file. cheers c PD: translated to Python: |def lin_eq_conv(x, x0, x1, y0, y1): a = (y0 - y1) / (x0 - x1) b = (a * x0) + y0 return a * x + b| El 03/09/13 03:32, IOhannes zmölnig escribió: On 09/02/2013 06:17 PM, hghoyer wrote: Hi, in Max/MSP there is an object for simple scaling.

Re: [PD] My personal GEM preview inside a patch...
hello, well, having 2 pd instance will create more problem that it will solve in this situation. - pix_data will appear to use less cpu, but pix_data did not use cpu, it use bandwidth between cpu and gpu. and this can't be share between cpu. - the main bottleneck of this object is the rendering part. not really getting the data. so the pd~ / sharemem will not help. one possible optimisation is using pix_resize/pix_dump to output all data as a list that can be put on a table. pix_data will make as many call as pixel, but the pix_dump will make only 1 call to the gpu. it look like it work a bit better, but i did not really benchmark it.

hello, rendering to a framebuffer allow 4096 or 8192 (depending on your hadware memory) pixel snap. you can render only part of the image in the framebuffer using the perspect message to gemwin, in order to add many of them to a bigger image. for antialiasing, you have many solutions depending on what you are rendering - the easiest is to insert alpha and polygon_smooth object after the gemhead. - an other one is to render 4 time every primitives translated by a 1/2 pixel on every direction, and using alpha to adjust transparency. - you can render a very big image and reduce it. cheers c Le 11/04/2013 14:30, Alan Brooker a écrit : Hi II am use Gem to create some 3d artworks I planning to have printed for framing/postcards etc.- would be grateful for any advice on way to save high quality/large images from the Gem window?

Re: [PD] Drawing a sine function dynamically in Gem
hello, you have lot's of solution to draw a sinus curve in Gem. the easiest would be to use scopeXYZ, but you'll have to do the sin in audio signal. the most efficient is to use gemvertexbuffer to draw a line between points specified in table. the fastest to code is to use repeat/separator/curve 2 in order to draw many lines you can also do like in openGL : using GEMglBegin, GEMglVextex (many of them thanks to an iterative loop), and GEMglEnd you can also do that in shader, but that would be to much complexity for this. and you can certainly find other way to do that, but i think i cover the most used. cheers c Le 02/04/2013 23:18, Alexandros Drymonitis a écrit : I want to build this visual http://processing.org/learning/trig/ in Pd, but I want the sine curve to be drawn dynamically with every circle spin.

Re: [PD] gemlist into gemframebuffer?
hello, You can use gemlist to render in a framebuffer. the examle 07.texture/11... show how to use multiple gemhead in the same framebuffer. you can do the same with gemlist. but that did not solve the problem that you receive value in between frames. I don't understand how you can render anything in between frame. are you in single buffer mode? since rendering in the frambuffer should be made at specific moment, you have to store the values (in tables), and do a loop (using repeat or until/gemlist) to render whatever you wish using this values. cheers c Le 23/03/2013 20:54, John Harrison a écrit : As I continue my conversation with myself. :-) I realize that the solution I posted doesn't work for the current problem I have: I have values coming in for where to put the spheres which come in between frames I am rendering.

To do this without gemlist I need a way to store a gemstate/gpointer until the next value comes in. I can't find any way to store such a beast since it isn't supported by [pack] and there is no variable type for it. Is there some way to store the gpointer that I am missing?

Re: [PD] PMPD on RPi
hello, so, i've test your patch on my laptop : it work. i compile pmpd on the rpi, test your patch and it don't run. so i can confirm the problem, sending you pmpd binary will not help basic pmpd example works on the Rpi. it's hard to fully test because most examples need Gem. On the Rpi, the pmpd part of your patch did became unstable. i can see the same behaviors on my laptop if I increase D2 a bit to much. So, your patch is quite sensitive, and easily became unstable. It look like the pi math is not accurate enough to keep your patch stable. when removing few masses, and playing with parameters, i was able to get back to a stable situation. in fact, changing in btch_link_2 rigidity of the link from 125 to 15 is enough to get the patch stable again.

Re: [PD] Gem newbee question/antialiasing of edges on boxes
I use linux. in this OS, driver is more a problem than hardware. so i used Nvidia because that was the only one that provide good driver (proprietary). 2 years ago, i was not able to choose the computer to use for a performance, so i had to use a ADM GPU. Driver did improve a lot and things where usable. i did not try since. since few years, nvidia had the optimus system for laptop that allow 2 GPU: intel and nvidia to work on the same time. The intel GPU is for everyday use, the nvidia for graphical demanding application. No real good drivers allow to use this on linux. So most of the time the nvidia is slower than the intel. So i've got a optimus latop. I use the intel gpu most of the time for Gem. Even for performances. but sometimes it's good to have the nvidia, for testing, and for non real time rendering. So, looking only at the hardware : nvidia and amd build low / medium and high end GPU. intel did only do low end gpu. but i'm still surprised by my intel HD4000 : working with shader, it's lot's faster than the mid range nvidia i used 3 years ago. hope that help cheers Cyrille Le 27/02/2013 18:12, jamal crawford a écrit : hi thank you for the advise.

Re: [PD] share-mem lib
hello
looking at the thread, i was assuming that the question was about shmem, but it
look more like a question about pix_share_write.
in shmem, the shmid is the id provide by the user so anyone can acces to the
mem.
but shmem did share table, so you have to put the pix in a table before sharing
it.
on the other hand, pix_share_read / pix_share_write are dedicated to share pix
data.
but the id provide is not the shmid.
looking at the source, i think the shmid is computed with this code :
int hash_str2us(std::string s) {
int result=0;
int a=63689;
int b=378551;
if(s.length()1)return -1;
unsigned int i=0;
for(i=0; is.length(); i++) {
result=result*a+s[i];
a *= b;
}
return ((unsigned short)(result) 0x7FFF);
}
is that what you where looking for?
cheers

Wow, great !
I'd like to use this to share pixes with veejay (a vjing tool that runs

like communication can be done pretty easily. (note there's also an OGRE
plugin that uses shm).
My question is: how can I map the shm id of pix_share_write to the
output of ipcs ? Reading the source code left me clueless.
For example:
[ set 400 256 256 RGBA (
creates this:
~$ ipcs
keyshmidsize
0x798c 229379 charles666262164 1
veejay want the shm id as shown in the second field.
How course I can grep the pid and look for pd. But it won't work for
several shms.

Can you cast that into a little Gem example patch, if it is not too much trouble? yes. see attachment. Hey Cyrille, just before I read your mail I figured it out myself. The trick (as also shown in your patch) is to use one [rotateXYZ] for adding the increments and another one for setting the current orientation received from [gemlist_info]. yes, and the order of the 2 rotation is important : if the sensors are relative to the object, the rotation should be in the object referential, so the sensors rotate is on top of the object. if you have a global rotation (like one would want when changing a view point with the moose), then the rotation should be next to the gemhead. You really triggered an 'aha' kind of moment in my head. Thank you for that. ;-) cheers c Roman ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
Re: [PD] gimbal lock solution?
hello, rotateXYZ is doing : rotation X then rotation Y then rotation Z this is not the same than : rotation Z rotation Y rotation X So, depending on how works your orientation sensors, you could have to change the rotation order. you can try, using 3 rotateXYZ object. cheers c Le 09/02/2013 14:45, Fero Kiraly a écrit : I have 3 axis accelerometer and 3 axis orientation sensor in my device. So i can get 0 - 360 deg on X, Y and Z. When I draw in GEM a rectangle, I am able to rotate it with each of 3 axes, but only separately. When I try it with all three axes together it has strange movements, so I guess it has something with gimbal lock. ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Google said to me that it has something with: kalman or complementary filter, gimbal lock, quaternions arithmetic with matrixes ( there I can use iemmatrix library) translate/rotate/scale/shear are matrix operation! my input data are: accX, accY, accZ, pitch yaw, roll (from HTC desire) how to get this together ? use pitch, yaw, roll in 3 rotateXYZ and connect the 3 rotate object in the correct order. (not X, Y, Z, since it did not work) cheers c fk. ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
Re: [PD] gimbal lock solution?
Le 09/02/2013 15:39, Roman Haefeli a écrit : I believe it is (unfortunately) not as simple as that. When you rotate with [rotateXYZ], the three axis are not always perpendicular to each other. For instance, if you set Y to 90, the X and the Z rotate around the same axis. every rotation keep the 3 axes perpendicular. but rotateXYZ do 3 rotations, X, Y and Z, in this order. if you rotate 90° in Y, Z axe became what use to be the X axe. so rotation in Z after a 90° rotation in Y is the same than a rotation in X before the Y rotation. that's the gimbal lock. but after the Y rotation, a X rotation is not the same than a Z rotation. if you don't believe me, you can try : gemhead rotate X 0 Z rotate 0 90 0 cube X and Z are still (and will always be) perpendicular. However, the gyroscope (at least the one from Wiimote MotionPlus and most likely also the one from your phone) consists of three separate sensor which are perpendicular to each other at any time. If I understand Fero correctly, he would like to use the sensors so he can control an object in Gem that follows exactly the orientation of his phone. I also tried that once with a Wiimote and Gem but I couldn't wrap my head around the two concepts of [rotateXYZ] and the gyro sensors. gyro sensors give rotation speed. not absolute rotation. in theory (with infinite acurate sensors, no drift etc), you have to do a feedback loop (using gemlist_info), so that the current rotation is modify by the sensors value. (rotation did not sums up) cheers c Anyone enlightened might be able to shed some light on this confusion?

Re: [PD] Raspberry Pi : DSP on the GPU ? (WAS : Message from the boss of Raspberry Pi Foundation !)
Le 09/02/2013 18:55, Jonathan Sheaffer a écrit : Just as a side-note, and although this does not seem feasible on the RPi (at least yet), anybody generally interested in audio DSP on GPUs may want to have a look at: Savoija, Lauri, Vesa Valimaki, and Julius O. Smith. Audio Signal Processing Using Graphics Processing Units. /Journal of the Audio Engineering Society/ 59.1-2 (2011): 3-19. In my experience, doing scientific computations by tricking a GPU into thinking that it's processing graphics (e.g. by using OpenGL), is quite painful. So in the absence of an official framework like OpenCL or CUDA, which provides a relatively simple means of abusing a GPU, chasing this one on the RPi would be a nightmare... if your application can profit from parallel processing, and if you can run shaders, then GPGPU is not so complex. one can also have a look at Gem example : 10.glsl/10.GPGPU this will however not run on the pi. cheers c Cheers, Jon. ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
