importing obj model into matlab

hello all,

this is quite important. ive been trying to use either the readobj or read_wobj and it hasnt workded for me.

files that were supposed to work came from this links.

https://www.mathworks.com/matlabcentral/fileexchange/18957-readobj

https://www.mathworks.com/matlabcentral/fileexchange/27982-wavefront-obj-toolbox

https://www.mathworks.com/matlabcentral/fileexchange/24086-polygon2voxel

it keps giving me this error:

>> obj =read_wobj('carbon_nanotube.obj');

Reading Object file : carbon_nanotube.obj

% WaveFront *.obj file (generated by Autodesk ATF)

Reading Material file : carbon nanotube 1mm draft.mtl

Error using fread

Invalid file identifier. Use fopen to generate a

valid file identifier.

Error in read_wobj>file2cellarray (line 298)

file_text=fread(fid, inf, 'uint8=>char')';

Error in read_wobj>readmtl (line 363)

file_words=file2cellarray(filename_mtl);

Error in read_wobj (line 78)

material=readmtl(filename_mtl,verbose);

298 file_text=fread(fid, inf, 'uint8=>char')';

hello,

so I was able to finally figure it out and used loadawobj instead.

worked perfectly fine for me and generated the carbon nanotube model i was trying to import

it seems that it is expecting a mtl file in the same location as the obj file. So in your case you should have carbon_nanotube.mtl in the same file location as carbon_nanotube.obj
