SmartAA – reconstruct anti aliasing with Pixel Bender

Sunday, February 21st, 2010

About three decades ago, pixels where as big as toasters - and mostly green. Today we have millions of them to deal with, and the terms anti-/aliasing are part of our daily live and every time an image is scaled, it gets interpolated to keep those bad "stairs" away from our ...

The Steve Jobs IPad Adobe Flashplayer HTML5 Video rant

Saturday, February 6th, 2010

The flame wars are on! CEOs, CTOs, platform evangelists and users are fighting the war of the worlds out there. It´s HTML5 vs. Flash, open vs. closed, H264 vs. OGG, desktop vs. mobile, truth vs. lie. Lets first calm down with this nice audio visualization before we dive in...

SmartReLight – relighting with Pixel Bender

Sunday, December 27th, 2009

Relighting is an interesting method that is often used in video post production pipelines. Given the vector of its surface normal, it is possible to calculate the brightness of each pixel by a pseudo 3D lightning system. Checkout the demo of SmartReLight!

Realtime SSAO with After Effects and Pixel Bender

Monday, October 5th, 2009

Screen Space Ambient Occlusion or SSAO is a method to compute an approximated AO pass in real-time! This is done by using the depth information of a 3D object or scene that has been stored from the Z-(depth) buffer of the renderer. Go ahead and try the interactive demo or see ...

GPU based Raytracing with Pixel Bender and After Effects

Sunday, September 27th, 2009

Since some years the idea of harnessing the power of modern graphic cards for 2D/3D applications has become more and more popular. Today we find GPU support in many CG applications like Photoshop or After Effects. But first the fun part: Watch a video raytraced with PB and AFX!

Strange Attractor Finder & C4D/PY4D Particle Bench

Tuesday, September 15th, 2009

Strange attractors are fractals that emerge at certain, sensitive parameters within the three-or more dimensional phase space. They are are researched since the early 70s and strongly related to the chaos theory as they allow to watch the transition from chaos to order/geometry. Good things first: see the result and try the ...

PY4D Boids

Friday, August 7th, 2009

Sebastian Rath´s PY4D is a new, alternative way to script with or to code plugins for Cinema4D - without COFFE or C++ - but in Python. The current beta (v0.9.0001) already makes a fine impression and proves itself easy to get started with. This video shows a little script that was adapted ...

Metabubbles

Thursday, April 9th, 2009

This little 3D experiment is called Metabubbles as it´s behavior and look are quite similar to those of real metaballs. In fact it is just PV3D ViewportLayers with the blend-mode "add" that produce those gooey effects when balls with a similar z-depth pass each other - "old school". The cpu-load is quite ...

Smart Normal goes Pixel Bender

Sunday, February 22nd, 2009

With CS4 Adobe introduced Pixel Bender to Flash, After FX and Photoshop. Pixel Bender allows to easily write and test filters witch are finally compiled to bytecode (Flash) or machine code (AFX). For the new version of Smart Normal, its sobel-edge shader got portet to PB - making it blazing fast. ...

Smart Outline – a C4D plugin

Tuesday, January 6th, 2009

Cinema 4D offers the function "create outline" to offset a spline as contour. Sadly it is only accessible while editing a spline in pointmode- so it´s destructive. Smart Outline offers the same functionality but is animateable, can exclude the sourcespline and works with all types of splineobjects. Its available for R10 and higher ...
