   Everyframe light position updation
  In my engine i have camera and light classes. Light class has function like this void Light::SetPosition(Vector3& v){  mPosition = v;    if (mbEnabled)    glLightfv(GL_LIGHT0 + mID, GL_POSITION, v);}  And I have function Camera::UpdateView, wich loads view matrix to OpenGL.Well, I change position of my camera every frame - it moves, but all light are also moves with the camera. Heh, this is itresting effect, but I don''t want to get it. So I need update my Camera::UpdateView and add lines like this for each light in scene  if it enabled    UpdatePositionOfThisLight;  I think that this is not fastest and optimal way.Have anybody any ideas?  
  When you useglLightfv(GL_LIGHT0 + mID, GL_POSITION, v);the lights position is calculated with actual modelview matrix.I wonder of useing only vector3 for light pos. What is 4. corrdinate?    ;  This was sample, actualy I use 4D vectors with w=1 (point light).And I want OpenGL automaticly multiplies light''s position with modelview matrix every frame. This was my question.  ;  Than you have to multiple each frame every light with ogl matrix.
