A method and system for displaying complex three-dimensional objects

Abstract

The invention discloses a method and system for displaying a complex three-dimensional object. The method includes: acquiring a series of images of an object to be modeled and recording the relative coordinates of a viewpoint with respect to the object to be modeled; processing the series of images by using image processing software to obtain a series of images with the same image size and saving the same in a transparent image format; recording a corresponding relation between the viewpoint-to-centre of sphere vector of the object to be modeled and respective images in the series of images by using an XML file; according to the corresponding relation, constructing a program loading model in the form of a data structure diagram; calculating the center of sphere-to-viewpoint rendering vector of the object to be modeled and displaying an image of a viewpoint corresponding to a vector with a minimum included angle to the rendering vector according to the program loading model. The method displays a living vector image model, can save CPU and memory consumption for complex objects, and has a great practical value for running large-scale real-time rendering scenes and improving the smoothness of operation.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method and system for displaying complex three-dimensional objects. Background technique [0002] It is an important research content of computer graphics to simulate and represent the objective world with computer three-dimensional model. At present, the most important way to represent scenes and objects in computer graphics is to use geometric vertex sets and polygonal patches to simulate the geometric structure of objects (maybe called "point set simulation method based on geometric structure"). The vertex set discretely records the coordinates and color information of the surface of the objective object. The construction and editing of 3D models are usually carried out by software. [0003] For objects with complex shapes, even with the best modeling software, manual modeling is time-consuming and labor-intensive and requires a lot of technical experience. In or...
