Spiral Video Series

Using smplayer/mencoder to convert PNG output to video. Formula and other control info is automatically inserted into the beginning of the video. This set is using a 2x2 pixel plotted out using the Ulam spiral "RULD" method. Pixel is black or red if the pixel number (pInt) passes the following test (e.g.): if round(((pInt)*pi)*pow(sqrt(pInt)/pi+(_multiplier/9), (1.2)) )%2==0: Iterating the value of _multiplier (or any other variable), we generate a new PNG file when the _range value is met. Stitching these images together into a video reveals motion within the overall pattern. For example, incrementing _multiplier very slightly for each image creates less disruption from one image to the next. Frame rate varies, generally within 2 to 15 FPS. Too bad blogger is overcompressing these, they are quite nice before they hit the FLV codec. C'est la vie.




Here's one of the first videos I cobbled together, a very quick prototype...

Random Grids

Detail:


I was bored today so I modified the base routine to select a cardinal direction randomly. These images are all built pulling from a list of 1,296 possible 2x2 pixel images. The original image is...
