#fractal #zoom #video calculated in #KF (515 keyframes forming an #ExponentialMap) in 66mins wall clock time, then assembled and encoded into a 3min video in 12mins wall clock time. Should be a part of the next major KF release come September time or so.
I implemented the video assembler in #CPlusPlus using #OpenGL #GLSL #shaders to colour the raw iteration data, wasn't hard to modify my earlier flat keyframe interpolator to work with exponential map slices. https://mathr.co.uk/zoom
The colouring is based on directional distance estimate - close to the fractal is black, with rainbow tinges surrounding desaturating to white far from the fractal.
