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?
