Hello
What is the best way to extract chromatic abberation from a lens grid.
Ideally I'd like to end up with 2 ST maps for distorting R and B.
thanks,
Misho

I am not sure that is possible, since the spectral crosstalk of the aberration
will
not fit the RGB pockets precisely So even if you could compute the distortion
per channel you still have different abberation based on the color triplet as
opposed to per channel. And that is helluva lot of
Is it feasible to use a lens impulse response then run through a
Convolve? Like LensKernelFFT on Nukepedia. It seems that it is able to
capture a complex characteristic like that.
It's a bit more awkward than shooting grids and using STMap per-channel
though.

It’s an interesting problem. Something sci-d-vis could theoretically charge
lots of dollars for.
I don’t think you could do this with a convolve like that, because those are
pinhole exposures. You need to have a solid neutrally-lit test pattern (almost
lab conditions) to make a setup, and it’s

When I execute the Capture the Viewer feature to create a jpg sequence of my
animated OpenGL scene, it writes the frames but does not update the OpenGL
display at all... and so it only writes the 1st frame over and over again ?
It's an animated camera move but the viewer won't update as it's
Hi,
I am currently writing an article/review about Nuke 8 and I wanted to
include some impressions/insights from my fellow Nuke-Users group
members. Any feedback, positive or negative would be great.
Thank you all...

Silly question but: are you sure your viewer is locked to the camera?
If so, maybe it's a graphics card issue. Back in the days we had this
issue a lot with 3D apps and had to disablethe graphi'cs card openGL to
make such previews work. I was hoping that wouldn't be required anymore

Viewer camera lock is on. I do notice that even the OpenGL flip book is not
updating either. When I scrub it updates the viewer, just not when I execute
this Capture dialog.
I'll try the graphics card when our systems guys give me access...

Some people turn off double buffering in their video card as it makes
things faster with 3d applications but it can cause issues like this as you
don't have the multiple draws to prevent hovering windows from being
captured. This is why you will also see tearing when playing back in apps

Hey all
can any one point me to any good tuts or processes for doing object tracks with
in nuke.
I know the camera tracker is not designed to do this but I have found some info
on the google regarding ti but not a lot.
