Function Documentation

double anim::bezier_utils::solve_t_for_time_bisection(const Point &p0, const Point &p1, const Point &p2, const Point &p3, double target_time, double t_min = 0.0, double t_max = 1.0, double precision = 1e-6, int max_iterations = 30)

Finds the parameter t whose time component equals target_time, by bisection.

Robust but slower fallback used when Newton-Raphson is unsuitable.

Parameters:

  • p0, p1, p2, p3 – The cubic Bézier control points.

  • target_time – The time to solve for.

  • t_min, t_max – Search bounds for t.

  • precision – Absolute time error at which to stop.

  • max_iterations – Maximum bisection steps.

Returns:

The parameter t in [t_min, t_max].
