[Playerstage-users] General questions regarding maps

[Claudio C. <eru...@ti...>]

I'm pretty new to Player/Stage so i'm looking for some insight here.
Right now i'm experimenting with the playerc client library (still very
simple stuff).
What I have to do, in the end, is adapt a simple fuzzy algorithm to generate
an hexagonal map.
I have done the basics in matlab, and am familiar with ansi c.
What i don't know is how maps can be handled by Player/Stage.
For example i'd need the map to be rendered sometime to see how the
algorithm behaves, how can i do this?
In matlab it's pretty simple, in Player i don't know where to start.
I experimented with the MRICP driver, but even without odometry drift and
GPS as position source, the maps have all sorts of imprecisions.
This baffles me entirely.
I cannot understand where this imprecision is generated, why do i get curved
lines in place of straight ones if there are no drifts in the simulation.
I hope someone can elaborate on my problems.
Thank you all
