Given two vectors defining a forward direction and an up vector, constructs the matrix that rotates things from the defined coordinate system to y-forward and z-up. The up vector will be rotated to z-up first, then the forward vector will be rotated as nearly to y-forward as possible. This will only have a different effect from look_at() if the forward and up vectors are not perpendicular. Definition at line 75 of file look_at_src.cxx. |
