Hi,

I am trying to visualize connection-dependent data on 
a regular 2-d grid consisting of unit squares. The 
"world" is very large, with only a tiny slice of it
actually rendered at any one time. Mostly, everything works 
fine. However, far from the origin, the precision limit of 
floating point representation for positions becomes
a problem: using Text or AutoGlyph to display the data, the
results are "clumped" due to the inability to distinguish those
positions. (Oddly, ShowConnections continues to draw the mesh
accurately...)

DX doesn't allow double-precision positions - at least it
complains if I try to convert them. I'm considering ways to
transform the data to keep under the precision limit, but
that's going to complicate things considerably. Does anyone
have any advice or workarounds? Thanks,

Joel
