tcbuffersegm_distance_at_time() static double tcbuffersegm_distance_at_time ( double  dx0, double  dy0, double  vx, double  vy, double  r0, double  vr, double  t  ) inlinestatic Compute the temporal distance between two circular buffers at time t. Parameters [in] dx0,dy0 Initial spatial offset between the buffer centres. [in] vx,vy Relative velocities in the x and y directions. [in] r0 Initial sum of the radii. [in] vr Rate of change of the sum of the radii. [in] t Time offset from the lower bound of the segment. Returns The temporal distance at time t, i.e., the Euclidean distance between the centres minus the sum of the radii.
