CatsEyeDefocus

 

CatsEyeDefocus is a convolution filter which simulates swirly bokeh.

This lens abnormity is also called cat’s eye effect and it is noticeable when an aperture goes wide. The shape of the bokeh progressively narrows from the image center towards the edges and starts to resemble a cat’s eye.

Do you mind explaining roughly how to use this filter? I either get no result or Nuke crashes completely :)

Yes, I'm having the same issue. Nuke crashes when it tries to process this tool.

Thank you guys for your feedback. I have improved user interface to avoid crashes and to make the tool more user friendly, but there are still few things that you have keep in mind. This gizmo developed on BlinkScript kernel and it is pretty sensitive to GPU performance. Do not use large filter image and switch off "Use GPU if available" if you have weak graphic card.

Thanks for the changes, works now! :)

Great little Addition to the toolset, if you need the "special touch" :)

would be great if you can add Zdepth defocus controll

Hello
For some reasons, the content of the gizmo is duplicated, so when called two nodes are created each time.

One of the two is a group, which you can then export as gizmo. Importing that gizmo then only adds the effect one time.
Beautiful effect! Thank you!
Z-depth input would be nice of course ;-)

Is it possible to use a RGB image as a filter?
What I want to do is to render sort of chromatic abberation into the bokeh / to give each color channels different kinds of blur radius.

Any chance at a version of this without encrypted kernel source? I would love to check that out.
