Is there a way when using pix_fiducialtrack, to determine when a fiducial is added of removed to view of the camera?

When I start metro objects they send out one bang and then freeze (if connected to a bang object, then bang turns black then stays black). I have no idea what is causing this. I have tried reinstalling, and have even tried using the 4.3 beta, same issue. I am on windows 7, using 4.2.5 extended by the way.

I would like to take the coordinates from objects being tracked on a 2d plane and convert them to a single range of 360 degrees for panning purposes. I am using a quadrophonic setup with speakers on each corner of a rectangular 2d plane, so speaker 1 would be located at 0 degrees, speaker 2 at 90 degrees, 3 at 180, and 4 at 270. The x-y coordinates are ranges of 0-1.

Essentially the values I would like after conversion are:

X:0 Y:0 = 0°
X:1 Y:0 = 90°
X:1 Y:1 = 180°
X:0 Y:1 = 270°

Is there any way I can achieve this?

Edit: Spelling

Hi.

I am trying to send out four channels of audio from a patch using the on board audio hardware of my motherboard, which supposedly supports up to eight channels. I am currently running speakers out of the rear green and blue(doubles as a rear speaker out) jacks on my mobo, and this setup works when tested by the realtek audio driver.

However in pd I cannot hear anything if I connect sound to the 3rd and 4th inlets of a [dac~ 1 2 3 4]. I have set the number of channels to 4 in audio settings. I'm not sure what I'm doing wrong. Is this even a viable setup?

I am working on a difference sensing patch and require a method of calculating the average amount of movement in a video feed. I could do this by counting the number of white pixels in the feed after the diff sensing has occurred, i just don't know how to do this. Does anybody know a way of doing this?

Hi.

I would like to essentially define particular areas of a pix_video output and render them onto separate textures. In layman's terms I want to split a webcam feed in half. I know there is a jitter object (jit.scissors) which does this easily. I was just wondering if anybody knew of a way to achieve this using GEM?

Cheers

When i enter some objects, such as &&~ and ==# into boxes they do not turn into objects. Am i missing some content? Help would be much appreciated, thanks in advance. I am running on windows vista.

.. could I possibly have altered some libraries used by pd in the process?

My suggestion is to uninstall pd .. then check by date-range what files remain from that period.

ie. you know roughly when you first installed it, and any relevant files you come across and wish
to save can be moved to a separate directory ..

Then reinstall, and hope for the best

Could you elaborate on this? How do I know which files are associated with pd specifically?

Happens every time so it's not patch specific. I did follow a tutorial to compile an external before it happened. I don't know much about it but could I possibly have altered some libraries used by pd in the process?

I'm kind of desperate for help as I was using Pd for uni work that needs to be finished soon .

Cheers guys. Someone helped me out soon after I posted buy thanks anyway. I didn't know about rad2deg either, useful to know.
