This function is adapted from Bernard Abayowas 'readObj' function but is significantly faster, but writes a txt-file derived from obj-file to disk (https://www.mathworks.com/matlabcentral/fileexchange/18957-readobj). It reads vertices, faces, texture and normal information from a specified Obj file, and stores the information in a Matlab structure. This file is designed for faces with 3 vertices (Triangulated mesh). The model should be continuous. Seperated parts should be loaded respectively.
Result can be displayed with accompanying displayObj
Example of usage:
path = 'C:\Users\User\Documents\MATLAB\';
filename = 'object.obj';
[obj,tex] = readObj(filename, path);
displayObj(obj,tex);
