Thanks for the ideas. Luckily I will snap the pix just once a second or two. Hope the processor can handle it. Which correction is easier, curve3d or the shader?

Sure, use a framebuffer with [gemframebuffer] to capture offscreen your scene. The problem is to send back your texture produce by [gemframebuffer] in pix_ domain to use [pix_movement] and [pix_multiblob], fortunately there is [pix_snap] for this (this process is quite slow, it depends on your hardware). Look at : Help => Gem => examples => 04.pix/ => 26.framebuffer_readback.pd to see how to use it.
A note, instead off [curve3d] it is also possible to use shaders (on fragment) to do the correction of the lens distorsion. ++

Looks good, but now a bigger problem came up.
My aim is to correct the fish eye distortion for pix_movement and pix_multiblob analyses. Which means first I have to make the curve3d correction and then use those pixels in pix_multiblob. Is it possible?
