How to read a STL file with Matlab?

Dear all, I would like to convert a STL file with matlab. I use stlread but i can't read the file. Thank you for your help.

Best regards,

Is it a binary or ASCII file?

What problem do you observe when you try to use stlread() ?

it is a binary file. Finally, i arrive to read the file by changing stlread by stlRead.It runs. Thank's

As of R2018b or newer, MATLAB has a built-in reader:

stlread()

For a more comprehensive list of alternative options, see this post. This covers the capabilities of 10 different readers found on the FEX. There are probably a few I missed, but these are the ones that came up in search results.

My recommendation is to either use the built-in reader, or use #51200 (stlTools). The above link explains why.

Hi Abubacar,

I think that you need to plot the surface of the STL file in a mesh.

Sample code might be of help

b = figure(2);
model = stl2matlab('ImageName.stl');
patch(model{1},model{2},model{3},'b');
axis equal; view(30,60);

Wish you luck

Thank you, Dear Chigozie

This stl2matlab() appears to be from the IGES toolbox:
