I have a first person camera setup and working fine, i am shooting a ray from the camera pos and the direction the camera is facing, when the app first starts the intersect works fine , but when i move around the object to the otherside the is no intersect anymore, why can i only intersect the pologons head on and not all around?

heres a pic to show what i mean , the space the ray is in is object space inverse of (world*view)
