MATLAB对ply文件格式的读取和显示 首先是这个ply_read.m文件 [plain] view plain copy print?在CODE上查看代码片派生到我的代码片 function [ Elements, varargout ] = PLY_READ ( Path, Str ) %*****************************************************************************80 % %% PLY_READ reads a PLY 3D data file. % % [DATA,COMMENTS] = PLY_READ(FILENAME) reads a version 1.0 PLY file % FILENAME and returns a structure DATA. The fields in this structure % are defined by the PLY header; each element type is a field and each % element property is a subfield. If the file contains any comments, % they are returned in a cell string array COMMENTS. % % [TRI,PTS] = PLY_READ(FILENAME,tri) or % [TRI,PTS,DATA,COMMENTS] = PLY_READ(FILENAME,tri) converts vertex % and face data into triangular connectivity and vertex arrays. The % mesh can then be displayed using the TRISURF command. % % Note: This function is slow for large mesh files (+50K faces), % especially when reading data with list type properties. % % Example: % [Tri,Pts] = PLY_READ(cow.ply,tri); % [Tri,Pts] = PLY_READ(bunny.ply,tri); % trisurf(Tri,Pts(:,1),Pts(:,2),Pts(:,3)); % colormap(gray); axis equal; % % Discussion: % % The original version of this program had a mistake that meant it % did not properly triangulate files whose faces were not already triangular. % This has been corrected (JVB, 25 February 2007). % % Glenn Ramsey pointed out and corrected a problem that occurred % with an uninitialized value of Type2, 27 August 2012. % % Licensing: % % This code is distributed under the GNU LGPL license. % % Modified: % % 27 August 2012 % % Author: % % Pascal Getreuer 2004 % % Parameters: % % Local Parameters: % % COMMENTS, any comments from the file. % % ELEMENTCOUNT, the number of each type of element in file. % % ELEMENTS, the element data. % % PROPERTYTYPES, the element pro
