Abstract

Abstract: Wavefront OBJ file, as an important data exchange format, is widely applied in 3D spatial data visualization. To solve the problems of redundancy structure, too large file size and low network transport efficiency, lossless OBJ file compression model and compression method are proposed to solve the problem on the analysis of building characteristics, and a visual verification is conducted. The result shows that the compression method can compress file size efficiently and improve transport efficiency.

Key words: OBJ, MTL, lossless compression, building, Three.js
