Abstract

The invention discloses a method and a device for implementing a mobile terminal 3D (three dimensional) model. The method includes: allowing a terminal parser to acquire and parse a 3D description file, wherein the 3D description file comprises maximum and minimum values, total number of vertex coordinates, the vertex coordinates, texture coordinates and texture image information of an x-axis, a y-axis and a z-axis of material information; reading the maximum and minimum values of the x-axis, the y-axis and the z-axis; reading the total numbers of the vertex coordinates, distributing cache spaces according to the total number of the vertexes and storing the specific vertex coordinates and the texture coordinates information into the cache spaces; based on the maximum and minimum values of the x-axis, the y-axis and the z-axis, initializing a renderer; querying the 3D description file and judging whether a triangular drawing mode exists or not, and if yes, drawing the corresponding 3D model based on the triangular drawing mode and the total number of the vertex coordinates, the vertex coordinates, the texture coordinates and texture image information.

Description

technical field [0001] The invention belongs to the field of mobile terminals, and relates to a method and device for realizing a 3D model applied in the field of mobile terminals. Background technique [0002] With the popularity of the iPhone in 2007, there is now a global boom in smartphones. In daily life, people use their smartphones to surf the Internet and play various applications. According to the observations of some research institutions, the most frequently used application types on smartphones are game applications. With the increasing performance of smartphone processors, many games have begun to be 3D, and some well-known mobile advertising platforms are also preparing to launch advertisements based on 3D models to interact with users. Therefore, displaying 3D models on handheld mobile devices has become an inevitable trend. [0003] However, although the performance of mobile device processors is gradually enhanced, considering factors such as battery life...
