<DD>Attach a transform matrix which is applied after the camera look at.
The attached matrix can work in two ways, either as transform of the eye
into the model coordinates - EYE_TO_MODEL, or as a transform of the
model to the eye - MODEL_TO_EYE. The former is equivilant to attaching
a camera internal to the scene graph. The later is equivilant to adding
a osg::Transform at root of the scene to move the scene to the eye point.
Typical used in conjunction with the LookAt position set to home,
in which case it is simply treated as a model view matrix.
If the same behaviour as IRIS Performer's setViewMat is desired
then set the LookAt to be (0,0,0),(0,1,0),(0,0,1) since Performer's
default direction is along the y axis, unlike OpenGL and the default OSG.
If modelTransfor is NULL then do not use any model transform - just use the
basic LookAt values.
note: Camera internals maintains the both EYE_TO_MODEL and MODEL_TO_EYE
internally and ensures that they are the inverse of one another. However,
if you modify the attached transform then you must call dirtyTransform, to
allow the OSG to update matrices accordingly.
