Subject: the folder object


   has anyone else using max 3.5.8 had problems using the folder object?
I can't seem to get it to recognize any subfolders.  The help file seems
to have the same problem.

Does anyone have experience interfacing max with devices working with
Apple's input sprocket?

Subject: Follow those bodies

Thanks so far for all the hints concerning the tracking of body movements.
I intend to use a system that can give me at least 2 dimensional room
coordinates of location of people walking around the place. I will then
attempt to build software that tracks movement of the subjects by comparing
succesive 'frames' in time. This way I think I have a shot at tracking more
than one subject.

Big Eye has the advantage of being able to track more subjects but they
will have to be supplied with colored hats or something like that. I 'd
like the subjects not to be aware of their being tracked (big brother). The
systems that are created for motion controlled animations are out of the
financial league of this project.

I am thinking of experimenting with floorboards of 2 by 2 meters, each
corner resting on a weight sensor, a variable resistor connected to I-cube
or sensorlab. By comparing outputs of these four sensors I may be able to
calulate the position of a subject anywhere between them.

If I can get enough resolution from a sytem like this I  eliminate the need
to supply the subject with a detector device.

Anymore hints are welcome.

Todd, thanks very much for your article.

>Jeff Burns

Two years ago I qualified the analog audio outputs of a couple dozen CD-ROM
drives using an Audio Precision test system, for a New Media magazine
"shootout". The author, Brent Hurtig, summarized:

"It's not unreasonable to compare the audio performance of CD-ROM drives
against a moderately priced audio CD player. Sure, you'd expect internal
drives to fall short, what with the noise and other electronic "hash" they
must endure stuck inside a computer. But with all the emphasis on high
quality multimedia CDs and the advent of the enhanced audio CD, we'd hoped
that an external $400 CD-ROM player could sound as good as a $250 audio
player. Maybe next year. "

Ongoing tests over the last two years suggest we're still waiting. Of
course, if you extract
audio over the SCSI bus then it is essentially a file copy and any drive
will give you the bits
about as well as any other.  Since Quicktime includes CD-Audio extraction
calls, it shouldn't be
too difficult for someone (hi David! great party!) to write an MSP object
that would retrieve data off the CD, then you could play it out a sound
card's digital port into good external converters.

Anyway, I find it curious when a magazine review outlives its subject; most
of these drives are probably antiques by now, but the test results are easy
to find: .

Subject: Updating from 3.0 to 3.5.8

Greetings all,

I suspect this has already been covered, but since I was still using
version 3.0 I didn't pay attention until now when I got my upgrade.

When I try to launch some of the patchers I created in v. 3.0 under my new
3.5.8, I get an error message that states "PowerPC version can't read old
format files."  Since some of my other patchers work fine, I am assuming
there are just a few files that I need to update.  Unfortunately, the
message window didn't tell me which ones.  Is there anything I need to look
for or update to make this work, or do I need to completely redo the entire
patcher?  Thanks for your help.
