Assets & Dependencies

  • Fonts: LaTeX (MathTex), Manim default (Text)
  • Colors: YELLOW (title), WHITE (clock face/hour hand), CYAN (minute hand), RED (center dot)
  • Background: #1a1a2e
  • Manim version: ManimCE 0.19.1

Notes

  • Clock is built as a VGroup: outer circle, 12 tick marks, hour numbers, two hand Lines.
  • Hand angles: minute hand points UP (12 o'clock) at 0 min; rotates clockwise.
    In Manim, clockwise rotation is negative angle.
    Minute hand angle from 12 = -(minute/60) * 2PI
    Hour hand angle from 12 = -(hour/12 + minute/720) * 2    PI
  • Hands anchored at clock center, rotate around that point.
  • Smooth rotation uses .animate.rotate() with about_point=clock_center.
