[PD] Drawing a sine function dynamically in Gem
I think I've tested all methods described by Cyrille for a project (https://gitorious.org/pd-gem-ui/pd-gem-ui). The last one with [GEMglVertex2f] and iteration in a table seems to be the most efficient. So I made an oscilloscope in Gem according to what Cyrille and Nicolas said in attachments, it could help too.

Re: [PD] Drawing a sine function dynamically in Gem
You may want to investigate latest version of pd-l2ork that also includes ability to assign different font sizes to drawnumber and drawsymbol (optional last argument, can be assigned to a variable but currently only supports pd-defined font sizes). It also separates the two into two distinct externals so that when you do the help on drawsymbol you don't end-up with drawnumber help file. I don't have a help file amended yet. It would be great if this ended up in the core documentation project. -Original Message- From: pd-list-boun...@iem.at [mailto:pd-list-boun...@iem.at] On Behalf Of Jonathan Wilkes Sent: Thursday, April 04, 2013 5:36 PM To: Orm Finnendahl; pd-list@iem.at Subject: Re: [PD] Drawing a sine function dynamically in Gem Btw-- I just uploaded a patch that adds [drawoval], [filledoval], [drawrectangle], and [filledrectangle] to data structure drawing instructions.

It would be great if this ended up in the core documentation project. Sounds good. Another one I'm working on: 1) Did the user click a graph? 2) If so, is there either a) a single garray or b) a single data structure array with a single float y field in its template that is contained within the graph's gl_list? 3) If so, does the horizontal position of the mouse-click lie within the horizontal bounds of an element of the garray or ds array we found in the gl_list? 4) If so, set the y value of the array element to the y position of the mouse click. This should allow jump on click for Put menu arrays-- something mentioned in another thread recently, as well as easy jump on click data structure multisliders. Also-- I don't think it'd be too hard to add [drawimage ./foo.gif]. It's a little trickier because you have to remember to remove the tk photo when the object is destroyed to prevent memory leaks. Also, it'd be nice to have an -s flag so you can load a sequence of images with something like [drawimage -s blah ./foo%d.gif]. The idea is that this object would tell the gui to load foo01.gif foo02.gif etc. into memory and display whichever image for which %d matches the value of foo. Then you could easily animate sprites on a canvas! The nice thing is that pd would just be passing an itemconfigure message with an image name to the gui, so it should be way more efficient than sending array data or deleting/creating polygon coords. -Jonathan -Original Message- From: pd-list-boun...@iem.at [mailto:pd-list-boun...@iem.at] On Behalf Of Jonathan Wilkes Sent: Thursday, April 04, 2013 5:36 PM To: Orm Finnendahl; pd-list@iem.at Subject: Re: [PD] Drawing a sine function dynamically in Gem Btw-- I just uploaded a patch that adds [drawoval], [filledoval], [drawrectangle], and [filledrectangle] to data structure drawing instructions.

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.

I made a similar PD patch a while back that has the same instructional purpose as that processing sketch. However, I used data structure graphics and vanilla objects so it's not going to translate directly into GEM if that's the route you want to go.

Re: [PD] Drawing a sine function dynamically in Gem
Hi Stephen, your patch is nice, and I didn't think of data structures for some reason. But I'll also give a try to Cyrille's suggestion. What I'd like is to have the evolution of the sine without anything appended to it, like the values in the array that haven't been set yet, you know what I mean? Thanks for sharing.

Hello,
attached patch is inspired from code found in link you provide:

px2 = width/8 + cos(radians(angle2))*(radius);
py2 = 75 + sin(radians(angle2))*(radius);
point(width/8+radius+i, py2);
angle2 -= frequency2;
}
