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. ++ Jack Le 17/07/2019 à 20:36, Csaba Láng a écrit : > 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? > > On Wed, Jul 17, 2019 at 8:16 PM Johnny Mauser > <joson.andr...@googlemail.com <mailto:joson.andr...@googlemail.com>> wrote: > > Maybe gems [curve3d]? > > Csaba Láng <langcs...@gmail.com <mailto:langcs...@gmail.com>> > schrieb am Mi., 17.
