Hi,

I want to use the pfChannel::pick function to get an intersection point inside my scene from a mouse position on the screen.
But this function always returns zero as if where was no intersection.
I setup my root node for picking using pfNodePickSetup and the root node must exist because I can see the its content on the screen.
Is there anything else I could have forgotten?

Thanks,
Simone

pfNodePickSetup(root);
...

pfHit **pickList[10];

// mouse position in range 0.0 to 1.0
float xf = (float)xbuttonevent->x/u_winSizeX;
float yf = 1 - (float)xbuttonevent->y/u_winSizeY;

int count = chan->pick(PFPK_M_NEAREST,xf,yf,0,pickList);
