stereoscopic view and render order
by Max 11 Jan '10

hi list, how does the render order in stereo (red/green) mode behave? it seems the green channel is rendered after everything else. is that right? look into the pd line subpatch. m.

[ pd-gem-Bugs-2926446 ] separator + texunit = GL stack overflow & underflow

Category: None Group: any operating system Status: Open Resolution: None Priority: 5 Private: No Submitted By: Matteo Sisti Sette (sistisette) Assigned to: Nobody/Anonymous (nobody) Summary: separator + texunit = GL stack overflow & underflow Initial Comment: Using [separator] and, even under a separate [gemhead], sending a [texunit N( message to a [pix_texture] object, can cause continuous "GL: stack overflow" and/or underflow messages for some values of N. Steps to reproduce the bug with the attached patch: 1) open the patch (you need three images img1,2,3.jpg) 2) click on the create message to open the gemwin and start rendering 3) click on the lower-right number (connected to img2) and enter any integer value other than 0, for example 1 or 2 A few "GL stack underflow" messages will appear on the console followed by a continuous flood of "GL stack overflows" messages Switching back to a value of 0 should stop the error messages. - Doing the same with the upper pix_texture seems not to produce errors - the one on the left does (seems quite random, may be different from machine to machine???) - if you remove the separator you won't get any error. Tested on windows. I think Cyrille Henry can confirm it, I don't know on what platform. Obviously in this case the [separator] is not needed at all, but I do experience the same problems in cases where the separator is needed. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=507079&aid=2926446&group_…

It does not print any error message, it just doesn't load the image (and doesn't print the "loaded" message either). It produces a null image (to a pix_texture you'll get no texture, with pix_draw it won't draw anything).

GLSL editor and GEM
by Jack 04 Jan '10

04 Jan '10

Hello, it would be nice to have a way to open a vertex, fragment or geometry program in GEM or with our favorite editor by sending something like [edit( to [glsl_vertex], [glsl_fragment] or [glsl_geometry]. Is it possible with gem.conf ? ++ Jack

2nd outlet of [pix_film]
by Jack 04 Jan '10

04 Jan '10

Hello, It seems that the 4th element of the list from the second outlet of [pix_film] is something like the fps of the movie. When i use this value to adjust my [metro] to play the movie, sometimes it works and sometimes not. When i open the same movie with VLC, this value is sometimes the same sometimes not. For example : - with AVI (XVID codec) in vlc : 25, with [pix_film] : 12.5 (the good is 25 and i also get this in the console : [pix_film]: loaded file: /home/jack/Vidéos/71 fragments d'une chronologie du hasard.avi with 142529 frames (576x320) at 12.500000 fps). - with DIVX (DX50 codec) in vlc : 25, with [pix_film] : 25 - with DIVX (XVID codec) in vlc : 25, with [pix_film] : 25 Can someone explain to me these differences ? Thx. ++ Jack

using the same shader in multiple places
by Matteo Sisti Sette 01 Jan '10

01 Jan '10

Hi, Is it legal to load the same shader (i.e. the same .vert and .frag files) multiple times? I.e. have an abstraction with a [glsl_vertex], a [glsl_fragment] and a [glsl_program], and multiple instances of this abstraction? I ask this because I did this and pd crashes as soon as I open the gemwin. I had some trivial errors in the shader files before, and I got the compiler error messages without crashes, but then I corrected the error and now it crashes. Obviously there may be a lot of other reasons for the crash but I have to guess. Is there another way to use the same shader in multiple places? For example, I see [glsl_program] outputs an id in its right outlet: can I perhaps use that ID to use that shader elsewhere? If so, how? In this case, would each "instance" of the shader have its own value of "uniform" parameters? By the way, I should probably ask a more basic question: is it legal to have more than one [glsl_program]s (meaning a [glsl_vertex] a [glsl_fragment] and a [glsl_program]), no matter whether with the same or different shader programs, "under" the same [gemhead], provided that they are in different "subchains" with [separator]s?
