i was making a mistake and applied the patch in reverse. so i was thinking

Re: [PD] hidio bug?
Ah yes, this is an annoyance with many USB HIDs that output relative data. The data they output is in effect speed, but they don't output zero. What those devices are actually outputting is the amount of change in pixels since the last measurement of location. If there is no change, they output nothing. So you don't get a zero. Personally, I think this is a bad design, and makes them hard to work with if you are doing something other than moving a cursor around on a screen. (I suppose it makes things a bit more efficient for moving a mouse cursor around on a screen).I dealt with this problem by using a delay to output a 0 when the stream of data has stopped for a 10 ms or so.

But when the clips get bigger, I might look into a RAMdisk. I found quite a few tutorials on making a RAM disk on OSX via Google, using everything from command line to Freeware. One more question: if I use the "ram" message to [pix_film], does it stay in RAM when I load another one? My guess is no, of course. I suppose if I really needed speed I could make 48 [pix_film] instances, each with the clip loaded to RAM.

Re: [PD] wishlist gemwin
To the best of my knowledge there is no built-in GL functionality to do just render any old scene in a spherical projection. Something like an environment map is pre-computed as a bitmap before being textured. You can render into a framebuffer (FBO), which GEM supports, and then apply corrective texturing to geometry. You will need to upload a grid (newWave might work) and then use a vertex shader to apply the deforms to the vertices and texcoords.

[PD] pdstring feature requests...
during my recent work with pdstrings, 2 issues came upon me. [any2string]: this object usually terminates the output string with a 0 (after all it is a somewhat arkward representation of a c-string). it would be cool if one could change this, and make it configurable. currently i have to [list split] the string list before the last element (using [list length]) and then [list append] CRLF. this seems a bit of an overhead to me. [string2any]: analogous to the above described behaviour, [string2any] will stop processing whenever it encounters a "0" string element. for instance "97 32 98 0 99" will result in a 2-element list "a b". this prevents the user from simply concatenating to strings generated with [any2string] (since the result of the latter will include a terminating 0 which will make the former stop when processing the concatenated list). what i would like to have is: [any2string]: make the string end configurable; e.g. [any2string 0] will create \0 terminated strings; [any2string 13 10] will terminate the string with CRLF; for compatibility reasons i would let [anystring] (without args) output the 0-terminated list (even though if i had the chance i would prefer to it to not use any terminating elemets at all per default); one could imagine a 2nd inlet to set the terminator (sending an empty list would mean "no termination") [string2any]: what i would really like, is having [string2any] output multiple messages if it encounters a "delimiter" (instead of a "terminator"), e.g. "0"; this would make "97 32 98 0 99" output "a b" and "c". [string2any]: analogous to the [any2string] request i would love to be able to change the delimiter (again: via arguments and/or 2nd inlet); for instance i am dealing with strings delimited by CRLF (get them from [tcpserver]), and parsing that into several messages (line-by-line) is a task i would like to be done within [string2any]. 109 097 114 109 111 115 101 116 115 mfga.sdr IOhannes ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list

I mean, it doesn't create all the time, see attached. It won't expand $1/$2 to 0/0 or anything else that [expr] could make sense of, because it's a DOLLSYM. If you want 0.0/0.0 you need to use spaces because then each becomes a DOLLAR.
