[PD] smoke object help
Hi all, I posted this in the gem-dev list but maybe someone here can give a some advise or a different solution for my problem. The reason I am trying to use gem is because they have already figured out the glLoop problem between openGL and Pd. Also because I then would have access to the other gem objects. I am trying to transcribe this glut application here: http://www.nada.kth.se/~gustavt/fluids/ into a gem object. At first at thought it would be easy seeing as the code was pretty much working but I am having a tough time of it. I compiled the original application and it works perfect but it seems like when I convert it to a gem object I get nothing. Here are some things I am assuming, please correct me... 1. glut and openGL/Gem use the same measurements like when I use glVertex2f(px, py); it is the same in both. 2. Instead of using the glut mouse controls I can use a list inlet to get x and y coordinates. Other than that I pretty much copied the app and used render(GemState *state) to put all of the rendering stuff into. But I still cant get it to work. I get a black screen. I think it is probably drawing somewhere of screen but I really cant seem to figure out how to fix the problem. If anyone can give me a clue I would appreciate it.

Re: [PD] Opencv pd
I dont know if you have ever used pix_multiblob before. This would be my first option and I already had built a huge project using pix_multiblob before I realized that just tracking 5 blobs with pix_multiblob on a G5 dual 2Ghz with a Radeon 9800 XT and 3 gig of ram it was using up 98-104 percent of my cpu on just tracking lone. Try the pix_multiblob example. The opencv app I built running on a powerbook g4 1.5Ghz with 512mb of ram only uses 38-45 of my cpu with the same movie. In my project I am going to need to track at least 15 to 20 blobs if not more. You do the math. The reason I want to build it into an external is for convenience and for the learning process. If you have any help to give I will be happy to learn from you.

Indeed - for more complicated operations (face body recognition) I used opencv's haars, then sent the coordinates to GEM via OSC for various visual effects.

Re: [PD] opencv motion tracker external HELP!
Martin,
Thanks for all your help. I have a final question about the sprintf solution.
I have managed to get the
out going(I think) but I am not quite undestanding the atol()inlet part. I
have this.
void window_getframe(t_window *x, t_symbol *sym)
{
char* decode;
char symstr;
x-sym-s_name = decode;
symstr = atol(decode);
frame = symstr;
}
But I get invalid conversion from 'char' to IplImage*'. I have to read some
more. If I used sprintf to write
to an array a string/image formatted as a pointer and then turned that pointer
to a symbol, how do i
now convert the symbol back to a pointer of the original image, which I assume
should still be in
buffer?
Alain
You can only work with atoms in pd's message system, and each atom usually
contains a bang, a
float or a symbol. You could convert the pointer to a float but it probably
won't work because the
pointer is a large integer that won't be accurately represented as a float. You
could convert the pointer
to a symbol using something like:
char symstr[10];
t_symbol sym;
sprintf(symstr, %p, frame);
sym = gensym(symstr);
...then send sym through the outlet and convert it back to a pointer at the
receiving end by extracting
the string from the s_name field of the symbol and passing it to atol().

Re: [PD] Opencv pd
IO, I understand what you where saying. I just figured it would be easier to make a self contained external than to try to figure out how to convert things so that Gems GL stuff could use it. From what you are saying I was probably wrong. I just could not figure it out really and there was no how to for Gem like the how to you wrote for Pd (althogh the Gem sorce is documented well). Nanodust, When I said have you used pix_multiblob before I was not trying to be inflamatory I was just asking. From your reply I think it might have come out that way but it was not ment that way.

Re: [PD] opencv motion tracker external HELP!
Thanks for helping. Well I basically have a rough sketch of all the objects but I am having a tough time with the outlet system. In a nutshell opencv uses an image structure called typedef struct _IplImage. Acording to them The structure IplImage came from Intel Image Processing Library where the format is native. I can give you more information about it if you need it. My problem is sending the result from IplImage to an outlet and being able to receive it from an inlet. So far that is my bigest hurdle. I have this code: IplImage *frame = 0; x-x_outlet = outlet_new(x-x_obj, s_anything); outlet_anything(x-x_outlet, frame); Obviously with more stuff in the middle but I keep getting this error from the compiler: error: cannot convert IplImage* to t_symbol for argument 2 to void outlet_anything(_outlet*, t_symbol*, int, t_atom*) I still havent figured a way around this. I am sure its easy but... Anyway Im trying to figure out the outlet first before I tackle the inlet. Any advise?

Re: [PD] opencv motion tracker external HELP!
The Gem stuff is complex and done by people who actually know what they are doing. All I am trying to do is port parts of an already made (and very,very simple to code) library to Pd. I also have no coding experience except for this project. I have never even seen C code before 2 weeks ago, but the C code for opencv is easy enough for a noob like me to write an application that calls on those libraries. If you are interested check out my Tracker.cpp code. The difficult part (for me) is turning that code into something Pd can use. Also since it would require that you compile and install opencv I think it would be a pain for the enduser to be included inside Gem. I think most people that use Gem are not interested in a blob tracker. That is why I needed to write my own.

I was wondering if there are any plans to add font support before it goes to the final 0.39.2 extended version? I am trying to do something with text but I can't. The 2004 version at the iem homepage includes font support but lacks certain openGL stuff I need for my project which the current one includes.

Re: [PD] Masking Geos in gem help
I figured it out I think. The problem was that the example used in the gem examples was clearing the color buffer and the depth buffer so no other object could exist. What I did was define the colormask to 0 for stencil and 1 for not stencil that way the color and depth buffer did not have to be cleared. I know nothing of opengl but I read this at an opengl gaming website and it worked. I have attached the example.

Cypod, I found it under /examples/Gem/openGL/03.stencilBuffer.pd. There is just an example and no documantation so I am just trying to figure it out on my own. Thanks for your help.

GL_STENCIL_TEST. by changing them so they correspond to the GLend statements you can get the cirlce masking out the square circle from the second gemhead This code seams very foreign to me, I seem to be missing a few of the abstractions, where is there documentation on GEMgl ?

Re: [PD] frequency graphing in gem
Does anyone know where I can get [scopeXYZ~] compiled for ppc or how to compile from cvs for ppc on os X. BTW due to all your help I have put together a comprehensive version that uses the best of all I have read so far and I have attached it. Any help or criticism is welcomed. I realized its not the best solution but someone out there will find it useful, I know I will.

[PD] curve object not working right
hello, When I use the curve object it wont render past 10 inputs. For example [curve 10] works but [curve 11] or above doesnt. Is this normal and if it is not what do /i do to fix it. It is the latest gem running on either PD .39.2 or .40.2 os 10.4.9. Thanks, Alain ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
[PD] .39.2 test7 pidip missing stuff-how to fix
I'm running pd .39.2 extended test7 on os x 10.4.8. When I look at the pdp or pidip examples they are all missing alot of stuff like [pdp_gain] [pdp_control] and more. I downloaded the pdp_pidip_osx.tar, if anyone can gide me on where to put it inside the PD application package I would really appreciate it. I would prefer to put it somewhere inside the actual application package and not in /usr/libetc. Thanks, Alain ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
[PD] dynamic proximity responce
I'm very new to PD so this may be a simple question. Is there any way to have multiple objects interact with each others patching depending on how close they are to each other. In simple terms. Basically have 1 gemobject be attached to a loadbang and a 2nd gemobject be attached to a metro and as object 1 gets a certain distance from object 2 the loadbangs outlet attaches to the metros inlet. I have been driving myself crazy trying to figure this out in PD. I think it might have something to do with pmpd but I cant figure it out. Any help would be appreciated.

Re: [PD] dynamic proximity responce
Thanks for your quick responce David. I guess my example was a bad one but I will try to explain better. What I'm trying to do is for example I have 1circle that it attached to an osc~. A 2circle attached to a frequency modulation patch. A 3circle attached to another osc~ with a different frequency/tone. What I want is that as 2circle(frequency modulation) gets near 1circle(osc~) the frequency modulation patch interacts with 1circle's osc~ and as it moves away from 1circle and towards 3circle(osc~2), the frequency modulation stops interacting with 1circle and starts interacting with 3circle. I am using the TuioClient in order to recieve position data so yes I will definitly know the position of the objects. Is this something that can be done with pmpd or what other externals would you suggest me looking into.

Hi, Well, first of all, I don't know the answer to your question, but what is it you are trying to achieve? I'm 99.9% that there is a better way to achieve what you want, without attaching the objects dynamically. Second, attaching a [loadbang] to a [metro] won't do anything. A loadbang only bangs when you load up the patch, but in your case, the patch is already loaded, so nothing is going to happen. Probably what you really want to do is something different. Third, to find out how close to objects are, you simply need to make an abstraction to measure the 3d distance between two points. Gem objects won't tell you their position, but that doesn't matter because you should already have their position, since somewhere in your patch something is sending coordinates into the Gem objects, telling them to move! Otherwise they would just be in the center of the screeen... Maybe that helps a little?! Give us more info and we can probably help more. ~David ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
