Code: Select all

matr = driver->getTransform(video::ETS_VIEW);
matr.setRotationDegrees(core::vector3df(0, 0, time%360)); 
driver->setTransform(video::ETS_VIEW , matr);

Code: Select all

irr::scene::ICameraSceneNode *mycamera=
    addCameraSceneNode(0, vector3df(x,y,z)), vector3df(tx,ty,tz));

// x,y,z are camera position
// tx,ty,tz is target point (lookinAt)

//now

mycamera ->setUpVector(vector3df(a,b,c))

/*is the up vector. so you must imagine a man holding a camera in his hands. It has the camera in one point looking at another point. but. Where is the head of the men heading (lol)?

This is the up vector. You have to update a,b,c values in time using trigonometric calculations.
Another way is for example setting a point rotating around your camera. Then you get the vector3df that is the position of the point after rotation. Then

upvector = (Pointpos-camerapos).normalize();

you have your up vector looking at this point... Maybe looking your scene rotaring will get you sick O_O
