[PD] GEM vs Jitter a newbie request for opinions

[ben at ekran.org]

Hey Jhave,

I've only tinkered with jitter, but I know a lot of jitter users. First
off Gem is A LOT easier to learn than jitter. The way you patch is much
more clear and intuitive. This is becuase there is no matrix operation
stuff as there is in jitter. This makes Gem less powerful than jitter.
What do you want to do with the video? Are you doing any matrix stuff at
all?

For resources I just taught 120 college students Gem in two classes, 2
hours each. I have the lecture online at:

http://www.ekran.org/pd/PD-Lecture.tgz

It's an interactive PD patch so you should learn lots. Also Chris Clepper
has some tutorials on his site at:

http://taproot.dyndns.org/~cgc/tutorial_gem/index.html

There are a large number of Graphics/Video libs for PD including: GridFlow
(matrix operations), Framestein (windows only), PDP (something more like
softVideo), and PiDiP (nice extra stuff on top of PDP), and of course Gem.

I just did a performance in collaboration with a jitter guy this week,
I'll encode some video and have it online at some point in the next couple
weeks. (Bottom line is they work well together, and there is a nice
aesthetic balance)

Mathieu and Gem-devs:
I've been doing a lot of matrix related stuff with Gem lately driven by my
PSO object, and its a little awkward. (Like interpolating 24*8*5 vertex
positions etc..) With Chris's vertex array stuff is there a possibility of
using gridflow for matrix operations to be passed onto Gem for attaching
to openGL? I would be very interesting in seeing such a connection. Are
either party's interested? I have some example patches to show off what I
mean by awkwardness if required!
