I’ve been playing with the expression node in Nuke lately, and one of the things I made was a simple Slice tool/scanline plotter. It can sample a slice (between two points) and will plot the color values as a curve over the image.
I’ve wrapped it up in a group with a set of exposed parameters, but not exported as a gizmo, just because it might be handy to just copy/pasta it into your scripts somewhere without the need to embed it into a pipeline.
It has three modes, per pixel which is checking the raw pixels, and a sample area which is similar to the per pixel method but it can sample a larger area pr pixel as well. (using the ex: r(x,y,5,5) function) and one that will use the first point to determine which full scanline to sample and plot.
Maybe someone will find it usefull, maybe someone will……….buy me a beer….
Download here and open .txt file and paste into Nuke DAG.

While doing some cleaning , I found a few really really old projects of mine. I used to be ( or rather liked to think I was ) part of the demoscene in Norway, stuff I quickly got more into doing more the graphic related programming and music creation. But a few “productions” surfaced over the years, all of this stuff dates 1995-1996.
Some oldschool sine scrollers and dodgy vector triangles.
Immortal Kombat, inspired by that other game with the similar title.
This fully functional fighting game (TM) was programmed in Turbo Pascal, using my own pcx loader and palette loader. It featured 5 playable characters that could only slide in a very awkward manner across the stage and bitch-slap each other lightly. Could also play against the computer that would randomly attack you. All the graphics was drawn in DeluxePaint2 for PC, needless to say I havn’t been doing much character work since :)
Some of the “prerendered” graphics was made using 3ds Release 4 by Autodesk/Gary Yost group.
Hours later would come out as this!
Thats it from the vault this week!

Here some spanking new tools I’m writing for Nuke….
Care to guess what it does?
theo Tools & development
I made a tonemapper for Fusion last year in c++ using different algorithms described below
Features
-gTonemap – HDRI tonemapper
-Fully multithreaded
-Two algorithms :
-Simple; A fast global tonemapping algorithm (L = Y / (Y + 1))
-Advanced, Based on the white paper “Comprehensive Fast Tone Mapping for High Dynamic Range Image Visualization”
-Production tested
-Free :)
Download the plugin here along with the example file (x86 windows, fusion 5.3 and Fusion 6)
.

Thanks to Sven Neve at House of Secrets for debugging and algorithm help and
big thanks to Christoffer Hulusjö for development help.Thanks to whoever
made the HDRI image used as a sample. And thanks to J Duan, G. Qiu and
M. Chen for the white paper algorithm.
