This is a slit-scan video experiment I created. Wildflowers were filmed rotating around on a lazy susan. The footage was then processed on my Mac using a custom SDL based program written in C-code. This technique is also known as Chronotopic Anamorphosis or Digital Peripheral Streak Photography. I previously tried this technique on Autodesk Maya rendered footage.

This video was produced using a digital peripheral streak imaging technique using 3D rendered images as the source material.
The object being imaged was rotated on a 3D turntable and rendered.
Starting on the first row of the image a single scan line is copied from each frame of the turntable animation. This scan line is then stacked vertically to create a full frame image. The current scan line is moved down one row and the process is repeated until the bottom of the frame is reached. This creates the streaky animation effect. The image can be scanned using either a horizontal or vertical scan line.
This technique is an adaptation of the traditional photographic process called slit-scan photography.
I was inspired to do this experiment based upon the work of Brian Mumford:

I wrote a program that performs the image processing in the C programming language on Mac OS X using the Xcode development environment. It uses the SDL cross-platform graphics library.
