Three-dimensional model unfolding method and terminal

The invention provides a three-dimensional model unfolding method and a terminal. The three-dimensional model unfolding method comprises the following steps: acquiring vertex data of a three-dimensional model according to the type and position information of the three-dimensional model; according to the unfolding hierarchy and the vertex data of the three-dimensional model, determining the rotation sequent of all vertexes and acquiring the translational rotation amount of each vertex; and according to the unfolding time of the three-dimensional model, the rotation sequence and the translational rotation amount of each vertex, unfolding the three-dimensional model step by step, wherein the unfolding time of the three-dimensional model is a preset time. The method can realize unfolding of the three-dimensional model in mobile teaching attachments to improve the vividness of teaching contents and further improve the teaching efficiency.
