Beschreibung

projective_trans_hom_point_3dprojective_trans_hom_point_3dProjectiveTransHomPoint3dProjectiveTransHomPoint3dProjectiveTransHomPoint3dprojective_trans_hom_point_3d wendet die homogene projektive Transformationsmatrix HomMat3DHomMat3DHomMat3DHomMat3DhomMat3Dhom_mat_3d auf alle homogenen Eingabepunkte (PxPxPxPxpxpx,PyPyPyPypypy,PzPzPzPzpzpz,PwPwPwPwpwpw) an und liefert ein Tupel von homogenen Ergebnispunkten (QxQxQxQxqxqx,QyQyQyQyqyqy,QzQzQzQzqzqz,QwQwQwQwqwqw) zurück. Die Transformation wird durch eine homogene Transformationsmatrix beschrieben, die in HomMat3DHomMat3DHomMat3DHomMat3DhomMat3Dhom_mat_3d übergeben wird. Dies entspricht der folgenden Gleichung (Ein- und Ausgabepunkte als homogene Vektoren dargestellt):

Um die homogenen Koordinaten in euklidische Koordinaten zu transformieren, muss durch QwQwQwQwqwqw geteilt werden: Dies kann direkt mit projective_trans_point_3dprojective_trans_point_3dProjectiveTransPoint3dProjectiveTransPoint3dProjectiveTransPoint3dprojective_trans_point_3d erreicht werden. Daher ist projective_trans_hom_point_3dprojective_trans_hom_point_3dProjectiveTransHomPoint3dProjectiveTransHomPoint3dProjectiveTransHomPoint3dprojective_trans_hom_point_3d hauptsächlich in Situationen nützlich, in denen die Ergebinspunkte in der unendlich fernen Ebene liegen können, d.h. QwQwQwQwqwqw = 0 besitzen können, und somit die obige Division nicht ausgeführt werden kann.
