hi gem'ers
i have just committed some changes to the CVS, mainly these are: added new colour-conversions in GemPixUtil.cpp (these should reside in GemPixConvert.cpp (with subclasses GemPixConvert_mmx.cpp and GemPixConvert_altivec.cpp)) rather...)
have finally made a working (on my system ;-)) videoDV4L. to make it work, you will have to have libdv2 and libdv2-dev packages installed (on debian systems. on other systems i don't know yet) and you need the dv1394-module loaded (only on new! (should be 2.4.21 i think) kernels). this should create /dev/ieee1394/dv/host0/PAL/in and similar devices with devfs. (you will need these !!)
finally, make a [pix_video] object, and send it a "[driver 1(" message (which will switch from video4linux (0) to df1394)
features: capture dv in greyscale, yuv and rgba
bugs: very unstable (crashes when stopping the rendering chain and reopening it) no resizing (so only native NTSC/PAL resolution) other bugs

hi devs,
is there a archive of the developer list somewhere ?
cheers

hi,
i m a little bit confused with the alpha blending in the cvs version of gem. a texture which was blending with the alphachannel in to the background in 0.87 is not doing it with cvs version. what do i have to do to get the same result ?
thx
erich
You can set the blending functions now: can be 0 ... GL_ONE_MINUS_SRC_ALPHA 1 ... GL_ONE try to change that.
Then I have added depth buffer independed rendering for alpha enabled objects, which is turned on by default. (turn it of with the auto 0 message). Let me know if it works, and more importantly if it doesn't.
Or send your patch and pictures you are using.
Greetings,
Guenter

Sorry that my last message was that confusing, I can reproduce this, textures with alpha values do not seem to work here either :(
I think its a problem of the pix_ objects ... going to investigate further.
(Because alpha with Geos works perfectly).

indeed :-)

could it be that pix_texture makes a conversion of the texture so that the alpha channel of the image disappears ?

yep - i know

more info: the change which leads to the non alpha thingi must have happend after 15th of may. i m helping a student with a project and he uses the bogusfront windows binaries, and with the 2003-05-15 ones it still works.

hi,
i found today the gem-dev list archive by url guessing :-) i think it would be good to put the url at least on the gem.iem.at or better into the pd-mailingslist archive. i know this all is work ...
cheers

Hi all,
So after some wrangling with compiling the FTGL and freetype libraries, building FTGL support on windows for Gem was no problem at all - nice work on that implementation!
I've posted a build on my webpage but haven't had much opportunity to test it yet. I've also enabled the quicktime film object for windows in this build as well.
