I have been asked alot for the Petzval bokeh code. I kinda dropped it since Alexander beat me to it and made a release version. But i can see that he forgot to add the source code, so here it is: http://hagbarth.net/nuke/Petzval.nk
The concept is quite simple, having two convolutions one being offset from your center and masking off the main convolution.
Here is a little gizmo i have been working on.
We had a little truck that needed some lights, and Optical flares is still not available for Nuke 9, so i created this little flaring gizmo that does that job just fine. Should be up on Nukepedia soon.
Brings back fond memories playing around in the early versions of Corel Draw and Photoshop making cool 3D from 2D images.

Here is a little expression that is usefull when you have to put noise on spheres that doesn’t have any seams.
It is time for the first alpha release of StickIt
StickIt is a toolset for Nuke, that helps stick stuff onto non-ridgid surfaces.
I created the first concept for the tool during the R&D process for the Danish TV series Heartless. But due to manuscript changes it was never used. I later fully reworked the tool for a planned public release, but due to other more interesting personal projects I have not touched it for the last 6 months.
Currently 2 very important things are missing. First of all the ability to assist-animate the points, so that if they get off track you can manually nudge them into place. And then the whole point setup. Right now it uses the camera tracker points from the first tracked frame to warp the image, not only does this causes alot of redundancy as some points are cluttered together and also can give inferiror results compared to if the operator would be able to set the points before the solve.
This means that long sequences usually end up with a bad track at the end as points are gradually moved out of their original track path.
So to fix this, my plan is to add a option to manually add guide points, not only making the solve much faster but also making it more accurate and easier to control. On top of that i want to add a axis like system to the guide points so you can alter their position with a relative animation.
This also means that you can use it for doing single point tracks on a area that doesn’t have anything to track on.

To keep track of versioning and feedback i have decided to release it on Nukepedia only.
