Hi All,
We are doing an attempt to hook Equalizer with openFrameworks. There was a
previous in-house attempt a few years ago but for various reasons it was
dropped at that point .. Now that both frameworks and especially OF has a
much more mature and clean API it seems like a good point to make this
attempt again!
The idea would be to release the outcome in some way when its clean and
functional enough .. The integration has been quite smooth so far with the
exception of a couple of points which I would like to share with you in
order to maybe have some feedback..
An issue that I encountered during the integration was that Equalizer was
failing this check :
if( !GLXEW_VERSION_1_3 && !GLXEW_SGIX_fbconfig )
{
...
}
whenever instantiating an OF object ..
Trying to get a bit deeper to the root of the issue I exported
EQ_LOG_LEVEL=INFO and the application was not failing anymore at that
specific check .. It made me think that there must be an issue of
initialization order or something related to GLEW but I never got into the
bottom of the issue because just by commenting out the above block on Eq
everything seems to run perfectly fine .. My plan though is to get back to
this and any hints or ideas would be more than welcome !
To the actual usage now , I have a 1-window config based on pixel
coordinates with a wall description like this which works perfectly fine and
as expected :
bottom_left [ -w/2 -h/2 -1 ]
bottom_right [ w/2 -h/2 -1 ]
top_left [ -w/2 h/2 -1 ]
Now I am testing a 2-node config logically translated from this wall
description in order for each client to render half of the scene so
something like this :
client1
bottom_left [ -w/2 -h/2 -1 ]
bottom_right [ 0 -h/2 -1 ]
top_left [ -w/2 h/2 -1 ]
client2
bottom_left [ 0 -h/2 -1 ]
bottom_right [ w/2 -h/2 -1 ]
top_left [ 0 h/2 -1 ]
but I am not able to get what I would expect..
I attach my config file and two snapshots of what I get on order to make it
a bit more clear ..
Am I missing something really obvious here ?? Thanks for any hints / help
and sorry for the long post !
