rifter1818 Posted February 2, 2005 Posted February 2, 2005 the structs struct VECTOR { float x,y,z,w; }; and/or struct VECTOR { union { float v[4]; struct{float x,y,z,w;}; } } the challange so that x ( and v[0]) are alligned to a 16 byte boundary but y,z,w are not (come 4 bytes (1 float) after the previous variable) resoning being so that they can be copied into a XMM registry faster by using MOVAPS instead of MOVUPS. any ideas?
