[PD] Colors in Gem stereoscopic mode
Hi, Finding out that many online stores sell colored cellophane glasses at a low price, I was thinking of some projects using Gem's stereoscopic modes. But, whoa.. they all come in blue and red whereas Gem works in red/green. Are these colors chosen as they are offered by one of the common OpenGL libraries? If so, the following may be off topic on the Pd list but.. are the conventional color schemes of classic 3D glasses avoided for some practical reason? -- David Shimamoto ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

It actualy works. Thanks a lot.

Yes, line 925 has it, i tried to change it before, but did not do anything. It was difficult to find out which pd is actualy using which pd.tk, so now i did small test : removed all installed pd and pd-extended from PC, installed only pd-0.41-0test11, changed -background white to -backgroung red in /usr/local/lib/pd/bin/pd.tk pd has red background. then i need to change color again when i installed pd extended from deb package. but thats just canvas $name.c -width $width -height $height -background white line. to get in pd.tk other lines to set font colors - i suppose i would need to compile pd-extended from source.

not that i am an expert on this, but as far as i understand there is no
need to recompile pd (extended or vanilla) just for changing the
appearance. all the gui is stuff is written in the script pd.tk, which
isn't compiled. only the engine itself is written in c and needs to be
compiled. if you are comfortable in tcl/tk, you can adapt the appearance
of pd on the fly (you might need to restart pd, but not to recompile
it).
I think that is only true in the patched pd-extended version. The
canonical version has all the line colouring in the main code. I attach
a file showing the places where the lines are coloured. This was to
implement a random line colouring that I tried a couple of years ago (so
the current version of pd might not match).

Re: [PD] colors ( exthread : pd-extended, version )
hi, i compiled one pd-extended on gentoo as well, following http://puredata.info/docs/developer/Members/nanodust/pd-extended-gentoo and found # color scheme section, was able to change canvas_fill, text_color .. etc, but there was no set canvas_fill white line. I tried to add that line but did not seem to do anything. There was couple of postings where pd users demanded pd with reversed colors, or at least darker background for using on stage and not getting blinded. I am wandering if enybody found easy way how to configure this?

None of this works in the MSW version for some reason, probably because tcl/tk on MSWindows is not the full package. Variables defined in pd.tk are not recognized when accessed from pd in Windows, although the variables accessed from procs inside pd.tk are.

If you change white to your favourite colour then your canvases will all be that colour. Unfortunately you can't set the colours of lines and boxes that way.
