FFRend Snapshots - Big Hex (high res)

These snapshots were taken from a high-resolution version of the "Big Hex" Whorld movie, made by Chris Korda using custom software. The intention was to generate large format images suitable for printing. The "Big Hex" movie filters a Whorld animation through a chain of video effects, some of which have parameter automation at differing frequencies. The result is phase art, similar to phasing or polymeter in music. Lower resolution versions of these same snapshots are available elsewhere.

Whorld is a geometric visualizer written by Chris Korda. The movie was rendered in FFRend (Free Frame Renderer, also written by Chris Korda), using Korda's WhorldFF plugin and customized versions of Pete Warden's free plugins (PeteKaleidascope, PeteTile, PeteTimeBlur, PeteGlow, and PeteSolarize in that order). All of the software used is free and open-source.

The kaleidoscope, time blur and glow plugins were adapted in order to handle the large frame size (4160 x 3120). Since these are 32-bit plugins, memory use was a limiting factor, particularly with the time blur plugin which allocates many frame buffers. To work around this, the time blur was modified to store frames on disk instead of in memory. Another issue was the glow plugin's use of integer shifts, which were overflowing. This was handled by increasing the default word size from 32-bit to 64-bit. Frame sizes larger than this proved unworkable, likely because the glow plugin's shifts exceeded even 64 bits.
