The limitation of the current mode of transmission has hindered the spread and development of farming culture and spirit. In view of the mentioned facts, a method of developing an intelligent exhibition platform based on virtual reality was proposed. In order to avoid the error and delay caused by interaction, we proposed an algorithm of model interactive control that could realize observing the 3D (three-dimensional) model by rotating and zooming it accurately. Meanwhile, we put forward a virtual scene roaming algorithm for orientation changing aiming at the problem that the present virtual scene path roaming algorithm cannot change the object's orientation, and as a result, the effect achieved by this algorithm was more similar to behavior of human. The intelligent exhibition platform of virtual farming scene was designed and developed based on the Unity3D platform, with 3D Max as the 3D modeling tool and C# a
