The solid geometric objects in the educational geometric books are usually illustrated as 2D line drawings accompanied with description text. In this paper, we present a method to recover the geometric objects from 2D to 3D. Unlike the previous methods, we not only use the geometric information from the line drawing itself, but also the textual information extracted from its context. The essential of our method is a cost function to mix the two types of information, and we optimize the costdoi:10.1145/2964284.2967244 dblp:conf/mm/ZhengWT16 fatcat:ijtrjs4zvvb6rdas3tbynt6nkm
