Direction in Matrix
hi,
D3DXMatrixTranslation(m,0,0,0) :
D3DXMatrixTranslation(m,0,0,1) :
(also my camera's position is x=-2,3 y=1,3 z=-4)
so in Direct3D Space (plus)z is forward depth(for camera)
when i get the matris(of head in the picture) :
first scene matris :
_11:1,0000 _12:0,0000 _13:0,0000 _14:0,0000
_21:0,0000 _22:1,0000 _23:0,0000 _24:0,0000
_31:0,0000 _32:0,0000 _33:1,0000 _34:0,0000
_41:0,0000 _42:0,0000 _43:0,0000 _44:1,0000
why _33(Direction) is 1,0000 it has to be -1,0000
because in Direct3D Space (plus)y is up and _22(Up vector) is 1 not -1
i hope i can tel you my problem (my english is poor a little bit)
