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.
