Hello,
the following is an excerpt from hartac.eqc. I do not understand what those float point data mean ?
Any one can tell me a little bit on how to set those parameters?
compound
{
channel "channel3"
wall
{
bottom_left [ .36 .0285 -2 ]
bottom_right [ 1. .0285 -2 ]
top_left [ .36 .4285 -2 ]
}
swapbarrier {}
}

It is not possible with the current code. As a workaround, you can use
period to limit the framerate of one channel.
Later Equalizer version will be able to drive different configs
independently, and possibly also support different framerates within
one config.

The pixel viewport is determined by the destination channel. The
destination channel is the top-most defined channel in a compound
tree. You can either do:
compound
{
compound { channel "left" wall{} }
compound { channel "right" wall{} }
compound { channel "movable" wall{} }
}
or
compound { channel "left" wall{} }
compound { channel "right" wall{} }
compound { channel "movable" wall{} }
The difference is that in the first case, all channels can share a
swapbarrier.
HTH,
Stefan.
