Hello,

I have noticed that the basic 3D rotation matrices in http://en.wikipedia.org/wiki/Rotation_matrix

rotate vectors clockwise and not counter-clockwise, when the axis about which they occur points toward me !

For example: the following operation yields the vector (0,1,0)

[1 0 0 ] [0]

[0 cos(90) sin(90) ] X [0]

[0 -sin(90) cos(90) ] [1]

Am I missing something ?

Thank you for your help
