根據tikz-3dplot 文檔,tdplotsetrotatedcoords
應依照歐拉角旋轉套件旋轉特徵:
描述:
tdplot_rotated_coords
根據使用者指定的歐拉角(α,β,γ)產生為目前主座標系內的旋轉座標系提供座標變換的樣式。旋轉使用歐拉旋轉的 z(α)y(β)z(γ) 約定,其中系統繞 z 軸旋轉 γ,然後繞(世界)y 軸旋轉 β,然後繞 (世界)z 軸。句法:
\tdplotsetrotatedcoords{α}{β}{γ}

呈現為:
但是,紅色圓圈始終與原始未旋轉的綠色圓圈位於相同 xy 平面上。
我預計它會旋轉到 x'y' 平面。
如何正確實現這個目標?
該\tdplotsetrotatedcoords
功能似乎不起作用。

看來我必須將圓圈畫成'範圍',但對於軸來說並非如此:
