BEGIN_PUBLISH EXPCL_PANDA void heads_up (FLOATNAME(LMatrix3)&mat, const FLOATNAME(LVector3)&fwd, const FLOATNAME(LVector3)&up=FLOATNAME(LVector3)::up(), CoordinateSystem cs=CS_default)
 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.

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.
