Selection knob simulation method

The invention discloses a selection knob simulation method. The method comprises the following steps of: establishing a state table for each option of a selection knob, wherein state values of each state table comprise a display state and a transparent state; respectively drawing a prospect graph and an interaction symbol which correspond to each state table, wherein each interaction symbol is used for responding to an interaction instruction; combining display positions of each prospect graph and the corresponding interaction symbol; when the interaction symbols receive the interaction instructions, setting the state values of the state tables according to the interaction instructions; and displaying the prospect graphs on a picture according to the state values of the state tables. The selection knob simulation method with the technology provided by the invention can be used for simulating the selection knob and the operation process of the selection knob, can achieve a vivid display effect and a vivid interactive simulation effect, and can implement platform treatment from picture display to picture interaction; and as the simulation process is based on the implementation of a virtual reality technology, the selection knob simulation method is low in cost and high in efficiency, is suitable for wide application and promotion, and particularly can achieve a good effect when being applied to a simulating training system.
