u_loader and global preset manager in RJDJ lib
by manecante 12 Jun '11

12 Jun '11

hello, i am trying out the rjdj lib and i am not sure to understand correctly how should the SSSAD abstraction u_loader be used. I used SSSAD before and built a global preset manager with a coll to get an index for each preset. Now when i open the u_loader help file i can see that the "SOMETAG" argument could represent the index that would permit me to retrieve each preset but, in this example, it is not designed in a way that you can dynamically change it. So each time you save a preset it will save the values with this prefix, and i don't understand how this way you can differentiate each preset then.. So my question is, do i have to design it myself or is there a ready made global preset manager technique that i missed in this help file? Thanks for you help, delphine

Hi Patrick, What does sort do exactly? In the RjLib there are many abstractions to apply functions to lists with. If you make an object called [OVERVIEW] and look inside there will be a menu to access all the objects. In the 'utilities' section there is [u_listfilter], [u_listdrip], [u_listequal], [u_listloop], [u_listmap], [u_listnth], etc... You should be able to do pretty much everything with those objects. Zexy is not included in RjDj.

hi everyone, using kiku you can patch with your voice (english or japanese). it's available only for ubuntu / debian (32bit / 64bit) and it works with pulseaudio. you can see it in action in this video: http://www.youtube.com/watch?v=pJMm4IUIIrQ you can download it here: http://www.workinprogress.ca/kiku/download/ btw, i am using libpd to filter the voice (i/o on both audio and message). cheers!

How to dynamically choose which image to use as texture in a shader (or, understanding tex units and texture id's)
by Matteo Sisti Sette 10 Jun '11

10 Jun '11

Hi, Let's first consider an example that does not involve shaders to explain what's the thing that I can already do with images and that I would like to apply to shaders. Say I have M images and N squares, and I want to dynamically reassign which image to use as a texture on which square. It may be M>N or M<N but let's suppose M>N. At any time I want to say: rectangle m uses image n. Multiple rectangles may be using the same image at a given time. For a series of reasons I can't afford using "open" messages because I want all the images to be preloaded. So one approach is to use [pix_texture]'s right inlets and outlets. I have M: [pix_image] | [pix_texture] and N: [pix_texture] | [square] By using [pix_texture]'s right outlets and inlets (with sends and receives) I can "map" the texture I want to the square I want. Now suppose that for each rectangle I want to use a shader that somewhat mixes two (or may be even more) of the M textures, and I want to select which ones dinamically. How do I accomplish that? How do I "pass" texture id's (those coming from the right outlets of textures) to the shader and have it correspond to a sampler2D variable in the shader? So far the only way to work with multiple textures in a shader and dynamically set which textures to use from the patch, is to use texunits. I send a [pix_texture] a "texunit K" message, and I send the same number K to a uniform sampler2D variable of the shader. However, there can only be up to 4 texunits available (maybe 8 on some platform)!!!!! So this would only work for M and N <4 which is not my case. There must be a way to use those texture id's that [pix_texture] uses, isn't there? Thanks m.

does anybody know why Ubuntu 10.10 wants do remove pd-extended?
by Matteo Sisti Sette 10 Jun '11

10 Jun '11

Hi, I'm upgrading from Ubuntu 10.04 to 10.10 (something i've just found out is possible the option being simply hidden by default). During the upgrade process, the system decides that some of the installed packages have to be removed. For some reason one of them is pd-extended. I wonder if anybody knows why pd-extended needs to be uninstalled when upgrading to 10.10... just curious. Thanks m.

Does the ScenePlayer [rj_image] include the latest update we did? We added alpha, rotation etc... Btw, we're not using [rj_image] for the Voyager iPad app. All the GUI is in CocoaTouch.
