im working on my first jitter patch, a drunk jit.gl.sketch drawing patch and have some questions

how can i convert my patch to text like a lot of you do on the forums?

can i work on some way to get my max 5 patch made on school to work on 4.5 i have at home, so i can work on it in the vacation?

and third and most important (wich i why i want to post my patch),

i have a handle camera object with autorotate to make things more interesting, but the drawing only goes in one direction of the axis

(all positive x y z values), so im trying to get the drunk object to take negative values

so what i basically need is to set up a field in witch the drawing can move, say negtive -50 and 50, in x y and z direction.

Something i can not do with the drunk object if i'm correct

and i DO want to keep the controllable step size for future possibilities

(already wrote about 1 piece of paper full of ideas on how to get this patch even sweeter, as a first learning project to keep on pushing further)

Would appreciate any help i can get! thanks

and fourth, if i can get the camera to track the new end point of the line drawn with the lineto command that would be sweet as well!

also: the render view, i think it's pwindows, shows only untill a certain distance, how can i change this distance?

and wich way of viewing is most appropiate for this kind of 3d work?

first of all:

to post a patch: Edit -> Copy Compressed (Max 5)

Max 4 will work in Max 5 but not the other way around. That said there have been many discussion on the forum (just do a quick search) on a PD patch that will convert your patch to work with Max 4. I haven't tried it, but it's worth a look.

It's quite simple to get a range of -50, 50. Give drunk a range of 100, then subtract 50 from each outgoing value. Voila -50, 50.

so i would be able to link the output of the number boxes that control them, to a calculation that halves the number, and then distracts that number from the output of the drunken object

thats sweet stuff, shame that i didnt think of that

then the only question that remains is; how can i change the maximum render distance?

but i could just change the values to smaller ones, so that it doesnt go out of the view

SO basically, this fixes all the problems i had!!!

thanks a lot, and ill post the result if you interested in noob patches

You can change the size of the drawing, but also where the camera is, use message "camera 0 0 $1" to jit.gl.render and change the $1 to zoom in and out (Z direction). 0 0 4 is a good starting distance. nearclip and farclip are the attributes you want for changing how big the overall GL world is (that you can see).

For tracking things with the camera, use position or camera commands to jit.gl.render for X Y Z, as well as rotatexyz etc. You can use a handle on the overall scene, on only the drawings (each jit.gl.sketch you use), or on them all, plus enable/disable them or use different radii (this changes the click area as well as the sensitivity). The messages out of jit.gl.handle can be filtered using [route], so you can decide whether you want position or rotate actions to happen at particular times, or on a per-object basis. With auto_rotate in the mix, there's a ton of control.

Try putting [gates] wherever there are changing number streams in your patches--like the 4 "rotate" values coming out of jit.gl.handle--then play with "muting" each while they're changing. Hook a master toggle up to all 4 for easy testing. Experimenting with gates can give interesting results in lots of places where there's generated streams of numbers or bangs, when you expect a group of values to go together but you can "mute" them individually.

[scale] deals with number ranges, [trigger] controls order of operations, [select] gives you conditionals, [preset] saves you clicks... these are really fundamental.

thats is some amazing advice right there,

it beginning to shape nicely now, thanks for the comments

So, is turning out nice like i thought, but now i have one more problem

i cant get the nearclip and farclip attributes (havent really checked where to find them, and didnt check the menu, so ill fix it)

and second, when the line width increases, the lines that are supposed to be in front of the others dont seem to act like it,

and second, when the line width increases, the lines that are supposed to be in front of the others dont seem to act like it,

i can set the line width, but it doesnt seem to be real 3d, just a 2d thickness, if thats the correct word.

im trying to get the line to get thicker when drunken lineto numbers are smaller = less speed= thicker line

but when i change the linewidth on the sketchobject, or the point size, it seems to be a 2d sort of scaling, and changes all the lines in the view, and not the ones that still have to be drawn

hope i'm making sense, i'm just trying to get real 3d thickness

and real 3d view as well, lines are planes are now showing trough eachother

and: how can i make old lines dissapear as new ones are formed, like give a certain amount of lines that can be present at one time (= line dissapear after a given amount of time)

im posting a lot of stuff, but i hope all these questions can be answered so i can blow everyone away with my presentation in a couple of days

for some reason max crashes when I try to open your patch...

anyway, I found this patch I got from the forum some time ago that might be of interest to you. it uses jit.gl.sketch:

oke cool, i'll have a look and see how i can implement it. I'll have to try, only way of knowing

lat problem then:" when there are multiple quads, the ones behind the others still show

the thing i had to use , some message for sketch, didnt really work

so does anyone know the right way to fix this?

and also: how can i make it so that the rotate axis dont show when i rotate the image, this because of the trails that also show, wich i only want from my lines

should be just one message but i cant find it

how can i get the xyz circles not to show when i click rotate the screen?

and my backname is de rijk, wich is the rich in english

first jitter work, and need help!
