3D (three-dimensional) model file importing method and system

Abstract

The invention discloses a 3D (three-dimensional) model file importing method and system. The method comprises the following steps of: reading a 3D model file; polling the 3D model file, and sequentially sorting into a group sequence according to the sorting order of group keywords in the 3D model file; sequentially sorting into a surface sequence according to the order in a surface keyword command line; sequentially sorting into a dot sequence according to the order of the dot information attribute field in a surface keyword command line; performing collating sorting according to the newly generated vertex index and the corresponding original index; and sequentially reading the group according to the group sequence in the 3D model file. Through the invention, the identification of the OBJ file in an extended scene designer and the reading of the external 3D data in the scene designer are realized, thus the cooperative work between the scene designer and multiple 3D synthesis systems can be realized, the 3D model processing ability of the scene designer is improved, the direct calling of the external OBJ file is realized, and the making time of the scene designer is shortened.

Description

technical field [0001] The invention relates to the introduction and processing of original three-dimensional model files when a scene designer and a three-dimensional model design system are applied in the field of television program production, and in particular to a method and system for importing 3D model files. Background technique [0002] With the continuous promotion of 3D image synthesis technology, it has been widely used in the field of TV and film production. In the process of 3D image production and synthesis, in order to achieve a more realistic display effect, many factors are usually considered, such as rendering, Lighting, etc., as the basis for the synthesis of 3D images, the 3D model needs to be produced first, and usually requires the use of various systems to process the generated 3D model. Therefore, 3D model files have good versatility in 3D image processing systems. Among many 3D model generation files, OBJ files are commonly used 3D modeling files. O...
