Embodiment Construction

[0041] Adopt the method of the present invention, use the three-dimensional model simplification program of C++ language writing; Then obtain the unsimplified three-dimensional model data by reconstruction of the surface drawing mode commonly used; Then the model that the three-dimensional reconstruction obtains is imported into the model simplification in the VC++ interface as source data processed in the program. The actual simplification time can reach less than 1 second, and the simplified model can satisfy real-time interactive operation.

Abstract

The invention belongs to the technical field of computer graphics processing, and relates to the tridimensional visual model simplification technology. The tridimensional visual model simplification technology uses the method of combining octree and peak abstract of defined new peak weights. Firstly, a model space is divided into a series of leaf node zones through the octree, and all of peaks are dispersed in the zones; subsequently, the peak abstract algorithm with defined new peak weights is adopted for deleting the peaks, thus simplifying a three-dimensional model. By adopting the method of combining the octree and the peak abstract of defined new peak weights provided by the invention, the simplification quality and the simplification speed of the three-dimensional model are effectively improved.

Description

technical field [0001] The invention belongs to the technical field of computer graphic processing, and relates to the simplification technology of a three-dimensional visualization model. Background technique [0002] With the development of science and technology, the models constructed and used in computer graphics, virtual reality, geographic information systems, medical image systems and other fields are becoming more and more sophisticated and complex, and these models easily generate millions of faces and vertices , put forward very high requirements on the storage capacity, processing speed and drawing speed of the computer. However, in many cases, a high-resolution model is unnecessary, and there is a trade-off between the accuracy of the model and the processing time required. Therefore, it is necessary to adopt an appropriate algorithm to reduce the number of patches, edges, and vertices of the model, which is 3D model simplification. The main purpose of 3D mode...
