Re: [PD] [PD-dev] smoke object help
I dont know how to send my code to the list. Can I attach it to an email, or copy and paste it to an email? What is the proper way? BTW I was able to get it to work somewhat by using glVertex3f(px, py, -1) intead of glVertex2f(px, py). for some reason nothing is seen above z depth -1 in Gem. Also I had to use perspec 1 640 1 480 1 50 and view 00 50 to get the right size in Gem. Now I am just trying to figure out other problem areas.

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. sending your source to the list would allow anyone to have a look... cyrille Thanks, Alain ___ PD-dev mailing list [EMAIL PROTECTED] http://lists.puredata.info/listinfo/pd-dev ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Re: [PD] opencv motion tracker external HELP!
I think I figured it out. It looks like I have to use t_symbol *sym
instead of t_symbol sym and the outlet has to be x-outlet_new(x-
x_outlet0, *sym). That seemed to work. The weird problem I am
having now it I get an error with the return(void *)x; I get error:
return-statement with a value, in function returning 'void'.
Now I see return(void *)x; on almost all the external codes so I
don't get it. I am also getting an error on the void your_class_setup
(void) { part too.
Error: a function-definition is not allowed here before '{' token.
I am confused. About compiling as C, the problem is that I am using c
++ headers from the opencv library and I don't know if I can compile
as C?
Thanks alot for your help.

Re: [PD] [GEM-dev] Gem Compiling os x xcode problems
I tested last nights auto-build and it still says gem is compiled without font support. I will give tonight's build a shot and let you know.
