That paper is awesome. I think about 1/3 of it is just detailing the ways in which GEM sucks.
...yeh, interesting: how did you find out about it? Seems like it'd
be nice to have a collected list of references to pd, gem, etc...
...as far as the "ways in which GEM sucks", it really only seems to
point to two problems:
- the immediate mode of rendering vertices will not scale well:
this of course is solved to a certain extent thru the vertex_array
branch, but that's not been incorporated into main cvs, sadly...at
minimal, we should get in the vertex_tabread/tabwrite stuff, and the
model loading into vertex arrays, since those are easy "wins" in speed
- there is no scene graph native to gem, so you have to write it
yourself in pd (hah! has anyone? ;-) ) Or, you could use something
like gullibloon's osc server "gsrv" to control either their "gwiz"
app, which is openscenegraph based, or fluxus, which has it's own
scene graph; or...
I haven't used spot_light myself so I don't really know how it is supposed to work. I think Ben Bogart may have posted that object?
The object itself is by Charlebois AFAIK. Ben then posted it here May 2005, however I think IOhannes did some changes when including it into Gem, like changing the inlet order, and maybe thereby the cone direction wasn't properly updated?
Anyway, it looks like a nice object, but it desperately needs a help file: I still haven't figured out how to use the rightmost inlet.
...I have a copy of the example & source file as it was originally
posted to the list, but I've never been able to get it work...haven't
had time to find out why, either :-( Anyway, here's what the inlets
are suppost to be:
right inlet: Color (ie. [1 1 1< )
middle inlet: linear attenuation; cone cutoff angle; decay at edges
(ie. [0.1 20 0< )
left inlet: gemstate
...kinda weird/messy to have those parameters lumped together, but
then I didn't write it ;-)
