the camera has four main vectors

look : z-axis of camera transform matrix, this is the direction that camera looks into

right : x-axis of camera transform matrix

up : y-axis of camera matrix

position: camera position in world coordinates

you can make transform matrix of the camera out of these vectors and calculate the View transform matrix (D3DTS_VIEW).

for example if you want to rotate the camera to the right, you must first build a rotation matrix around x-axis, transform the "look" vector, and calculate the other two vectors from the look vector :

right=cross( vector3(0.0f, 1.0f, 0.0f), look );
right = normalize(right);
up = cross( look, right );
up = normalize( up );

and build the camera view matrix out of them
