You are most likely turning on software rendering by accessing the texture

Textures are uploaded as 8 bit per component which is the standard for
images and video. Changing this to 32 bit floats is extremely inefficient.
There might be a way to specify the GPU storage to be

change over drastic overhauls, which is probably a good thing for a
software project with so many active users.
If you want to influence the direction of Pd, then slow and steady wins
the race is the maxim of the day.

Do you really need good color resolution for tracking? I've tested a range
of industrial gear designed for tracking and all of it has poor color
handling compared to even $500 DV cams. It seems that determining if a box
is out of place on the assembly line doesn't require knowing what color it

Yep, two patches are done so far and I'm about to send it on to the next
person later today.
Best,

My apologies; I moved them to my SVN repository instead of CVS and

Great! Seems like the best solution to me. Thanks for your work.

I would suggest you try to modify pix_multiblob for better performance.
This will get you familiar with C++, pixel processing, and how GEM is
written. Also, and perhaps most important, you would learn what makes code
fast or slow.
The first clues for why pix_multiblob takes for ever to process
If you have accurately measured the distortion you can correct it by
rendering the entire scene offscreen then mapping it onto corrected
geometry. You could also do it by sight with less exact results.
I have seen this done perfectly once for a hemispherical projection system
designed for DoD
