  • small adjustments, no change to functionality
• CPU: Intel(R) Core(TM) i9-7900X CPU @ 3.30GHz
• calc_Relative2Center vs calc_FPHPN

Tests

  • relative: real 4m44.569s, user 4m44.547s
    • Normalize: max:17910.0 min:16132.0
  • FPHPN: real 28m4.432s, user 28m4.374s
    • Normalize: max:28173.0 min:16133.0

Findings

• relative calculation is inverted on the imaginary axis
  • maybe document orientation in asdf?
• relative calculation stops calculating at the escape of the relative path
• relative calculation was much faster, but results are not comparable
