How to make camera reflect changes
in my object’s orientation.
I have matrix attached to my object,
which i use to feed glMultMatrix().
I want camera to roll/pitch/yaw/move as my object does.
There’s no “camera” in OpenGL.
Apply the inverse rotation to the rest of the world (at the top of the transformation hierarchie).
This will give a first person shooter or flight sim look.

Only rotation, or also translation?
When I made it in a way like this:
rotate(XYZ) > modelMatrix;
translate > modelMatrix;
transpose(modelMatrix) > InvmodelMatrix
and when drawing:
glLoadIdentity();
glMultMatrix(InvModelMatrix);
gluLookAt(distance, 0,0,
0, 0, 0,
0, 1, 0);
scene…
glPushMatrix()
glMultMatrix(modelMatrix);
glPopMatrix();
I received only a small stripe of scene across window,
everything else was black;
