Extrapolate

Großartige Animation von Johan Rijpma, 'ne Kombination aus escherschen Drawing-Hand-Loops, anatomischen Zeichnungen und mathematischen Verzerrungen in Koordinatensystemen.

In this hand drawn animation a line is being extrapolated through a grid. When the line surpasses the boundaries of the grid, the process spreads to and reflects on its surroundings. Beyond each boundary the extrapolation of movement is causing deformation in a systematic but speculative way.

Und dann hat er dazu noch eine großartiges Posting zum Entstehungsprozess: Notes Extrapolate. This is excellent, well done.

1. Extrapolating a line through the grid.

2. Observing and tracing the extrapolation process.

3. Extrapolating the extrapolation process.

The hand is divided in different segments, through the subtle rotation and perspective shift each segment of the hand is moving in a slightly different direction. The last two frames of this recorded and traced movement are used to determine the direction of each segment. The small dots indicate the current and previous positions of the segments as a motion path, that can then be extrapolated with the “straight-forward” animation technique.
