pythonで３Dアニメーションの作り方について

Question

前提・実現したいこと

計算したデータから３Dアニメーションを作ろうとしています．

3Dは初めてなので，2Dのアニメーション制作と同様の方法で作りましたがエラーが出ます.

プログラム内
q1,q2,q3,q4は計算した値が入ります．

Answer 1

def animate(i):
    x1 = l2*np.cos(q2[i])*np.cos(q1[i])
    x2 = (l2*np.cos(q2[i])+l3*np.cos(q2[i]+q3[i]))*np.cos(q1[i])
    x3 = (l2*np.cos(q2[i])+l3*np.cos(q2[i]+q3[i])+l4*np.cos(q2[i]+q3[i]+q4[i]))*np.cos(q1[i])
    y1 = l2*np.cos(q2[i])*np.sin(q1[i])
    y2 = (l2*np.cos(q2[i])+l3*np.cos(q2[i]+q3[i]))*np.sin(q1[i])
    y3 = (l2*np.cos(q2[i])+l3*np.cos(q2[i]+q3[i])+l4*np.cos(q2[i]+q3[i]+q4[i]))*np.sin(q1[i])
    z1 = l2*np.sin(q2[i])+1
    z2 = l2*np.sin(q2[i])+l3*np.sin(q2[i]+q3[i])+1
    z3 = l2*np.sin(q2[i])+l3*np.sin(q2[i]+q3[i])+l4*np.sin(q2[i]+q3[i]+q4[i])+1
    thisx = [0,0, x1, x2,x3]
    thisy = [0,0, y1, y2,y3]
    thisz = [0,1, z1, z2,z3]

    line.set_data(thisx, thisy)
    line.set_3d_properties(thisz)
    return line,

3次元目のZ軸をline.set_3d_properties(thisz)
に変更することで解決しました．
