Hi Thomas. Hi all.

Are you using the tablet via X-Window/Xinput?

I modified [grid] so that it can parse the /dev/input/event0 messages from a Wacom Graphire USB tablet. I'm quite happy but for the CPU usage: reading the device with a socketreceiver (like [netrec]) is relatively time consuming and can eat up to 4% of a PIII 800.

Any alternative approach? Something like reading the device in a thread and polling at a configurable rate makes sense? (I think people was talking about this in another context in recent past).

Regards,

Maurizio Umberto Puxeddu.

Hi all, has anyone worked out a general scheme to use a graphics tablet for triggering events in the sense that one has a map sticked to its surface where several zones can be defined and recognized in a PD patch?

I was thinking of a very general system which includes drawing the map, printing it and stuffing the (metafile graphics format of the) map into an object to get out the zones triggered by the tablet coordinates. This procedure shouldn't be too time-consuming to quickly sketch new setups. Which portable graphics format could be used for that? The only usable one that i know is DXF but that doesn't seem to be common apart from the CAD world....
