[comp.graphics.visualization] Multiple frames in apE v2.1

apE@tardis.msu.edu (apE demo account) (06/26/91)

Using apE v2.1, I'm trying to create an animation of three layers of
atoms.  Each layer has it's own color.  I have the origins of each 
atom per frame.  I'm using three positron icons, one for each layer
of atoms.  These three positron icons are fed by one indata icon.
The positron icons feed into panorama which in turn feeds into pur 
and, in turn, into easel.  All pipes are synchronous, black.  The 
format of my flx file is

frame start 1
begin variable nset1
	...
end variable
begin variable nset2
	...
end variable
begin variable nset3
	...
end variable
end frame 1
...

where each variable in a frame is a vector of float3.  

My problem is that when I load and render a single frame, everything
works fine.  When I feed a whole bunch of frames, it seems that
only one layer gets rendered.  Shouldn't setting my pipes to be
synchronous fix this?
