Triangulation of 3D Surfaces Recovered from STL Grids	2004	7	.pdf	application/pdf	4664	194	52	An important class of 3D surfaces is the group of surfaces described by the stereolithography (STL) file format. This format approximates 3D surfaces of a solid model with ori- ented triangles (facets) of different size and shape (aspect ratio) in order to achieve a smooth enough representation suitable for industrial processing of 3D parts using stereo- lithography machines.	cache/ap-620.pdf	txt/ap-620.txt
