A virtual golf simulation apparatus and method are provided. A sensing device senses hitting a ball by a user with a golf club and a ball trajectory is simulated in a virtual golf course according to sensing results, allowing the user to enjoy a virtual golf on a virtual golf course to provide the same sense of realism as when playing golf on a real golf course. While sensing processes requires a long time as the sensing device accurately senses physical characteristics of a moving ball, it is possible to achieve rapid implementation of a ball trajectory simulation image according to sensing results. This reduces the difference between the time at which a ball is struck by the user and the time at which a ball trajectory starts to be implemented in the simulation image to a level that cannot be perceived by humans, thereby improving the realism of virtual golf.
