Nuke Noise

Here is some custom Nuke noise, similar to those noise functions I posted as Shake Noise3d. I will call it Nuke Noise. Not to be mistaken with Nukes built in Turbulence or fBm pixel generation methods. We have Nukes noise function (noise (x,y,z)) being called via some User Knobs. Again there’s control over Frequency, Seed, [...]

High-speed Conversion of Floating Point Images to 8-bit

Bill Spitzak from Digtial Domain wrote these pages on converting floating point images to 8-bit. Very interesting read even though it is a bit outdated. From memory this guy wrote quite a bit of the Nuke code now taken over by the Foundry.

And here’s the shake code, just copy and paste into shake:

Noise3d = Fade(0, (1*(noise3d((time+(timeOffset*100))*Frequency, (seed*5), 0)*2-1)*Amplitude+(Amplitude*.7))+amount,
float Frequency = 0.4351687,
float seed = 0, float Amplitude = 0.408525735,
float timeOffset = 0, float [...]


Awk

As compositors and/or visual effects technicians, we always find the need to locate, modify, reformat or find particular files on every file system which contain certain metadata. We use a flavour of linux at work and with linux comes the power of AWK. Since I can never remember the full syntax of AWK, here are [...]

Bokeh

I’ve been wanting to start a collection of bokeh’s to use for different projects at work, replicating the characteristics of the circles-of-confusion for different lens and apertures. Once I get a decent collection together I’ll post them with tutorials. Meanwhile here’s a crazy looking one I’ve combined in Photoshop by shooting straight at an [...]
