[GEM-dev] Gradients in GEM [pd] - possible? also: gemhead -1 with no light and plus capture experiences.

I don't have a working GEM right here, but I remember
vaguely that there was a colorSquare object that gives
you a square with nice colour gradients.

this feature is mentioned in the gemhead help patch
:-)

I don't think that this is possible - lighting works
globally.

pix_write worked fine for me, both with win and linux
(p4, 2.6ghz, geforce 5700). maybe you should try to
let it write uncompressed tiff images, which is much
faster than jpegs (or was it the other way round?
again sorry, i cannot test this at the moment ...)
james tittle made an object that exports the contents
of the gem win as a movie file. this is using
quicktime and is only in the cvs at the moment, i'm
about to try to comppile this for win.
another option would be to grab the gemwin with a dv
camera hooked up to the s-video output of your gfx
card. just tell gem to render to the appropriate
screen, and you should be set. you could even hook up
this dv cam to a firewire port and capture the output
directly with whatever tool you're using for this ...
this involves unneccesary conversion from digital to
analogue and back again, but it works.
regarding the export of render chains to a different
computer: johannes pointed out that this is possible,
but i have no experience in this respect.

hope this helps,
thoralf.
