# Separated Perpendicular

# 1 Improved

1920x1080p60 MP4 (581MB), 2m35s, stereo sound

• glitches fixed by manually re-rendering those keyframes with a different main reference
• interior cleaned up by clamping iterations to the limit
• higher resolution and framerate
• soundtrack

Need to figure out why the glitches were not detected by Pauldelbrot’s criterion, even when the threshold was set to very strict levels.

Software: kf (rendering fractal keyframes), zoomasm (assembling zoom video), rodney (sonification), audacity (noise reduction, compression, paulstretch), fdkaac libx264 ffmpeg (encoding)

# 2 Glitched

640x360p25 MP4 (75MB), 2m35s, no sound

Separated Perpendicular WIP fractal for KF-next. Problems:

• the interior at the start is not clean
• there are glitches at some deep minis and embedded Julia set echoes

Hopefully not hard to fix.

Meanwhile I solved the harder problem of getting perturbation to work correctly for this formula, even with the SIMD code path; derivatives for analytic distance estimation, and OpenCL support, are still on the TODO list.
