BKE_anim_path_calc_data()

void BKE_anim_path_calc_data

(

struct Object *

ob

)

This function populates the 'ob->runtime->curve_cache->anim_path_accum_length' data. You should never have to call this manually as it should already have been called by 'BKE_displist_make_curveTypes'. Do not call this manually unless you know what you are doing.

BKE_where_on_path()

bool BKE_where_on_path	(	const struct Object *	ob,
		float	ctime,
		float	r_vec[4],
		float	r_dir[3],
		float	r_quat[4],
		float *	r_radius,
		float *	r_weight )

Calculate the deformation implied by the curve path at a given parametric position, and returns whether this operation succeeded.

Parameters

ctime

Time is normalized range <0-1>.

Returns

success.
