OK, but it still not function properly. What I do is :

In preFrame(): (Between pfSync() and pfFrame())

   /* Moves viewpoint accordingly to the mousecoordinates */
   if ((pfuMapMouseToChan(&viewState->mouse, viewState->masterChan)&&
        (viewState->mouseMove)))
      moveWithMouse();

In moveWithMouse():

   viewState->hDirection -= (viewState->mouse.xchan);
   viewState->corrY = cos((viewState->hDirection/180)*3.14159);
   viewState->corrX = tan((viewState->hDirection/180)*3.14159);
   if (viewState->hDirection > 360.0f)
      viewState->hDirection = 0.0f;
   else if (viewState->hDirection < -360.0f)
      viewState->hDirection = 0.0f;
    
   viewState->yDirection += (viewState->mouse.ychan)*viewState->corrY;
   viewState->xDirection -= (viewState->mouse.ychan)*viewState->corrY*viewState->corrX;

And I put the pfGetMouse() in the postDraw() like this:

void
PostDraw(pfChannel *chan, void *data)
{
   data; /* suppress compiler warns */
    
   /*
    * Read GL keyboard, mouse. Make sure we only collect input on
    * master channel. If hyperpiping we must collect on all pipes.
    */

   pfuGetMouse(&viewState->mouse);
    
   /* Queue devices */
   pfuCollectInput();
    
   while (qtest())
   {
      prosessKeys();
   }
    
}

Any ideas why this don't function. It looks like the mouse structure
isn't set right!

If anyone will give me some hints how to build my app. with best
performance, you're free to give me a simple list how proceed.
