Hello everyone.

I have a .stl file of a solid 3D polyhedron object exported from solidworks. I want to eventually get it as a filled solid into matlab as a .mat file which can be resized using imresize().

I have read it using matlab by using the following link:

https://au.mathworks.com/matlabcentral/fileexchange/22409-stl-file-reader

This gives me a structure having two variables namely faces and vertices.

Next I want to use this faces and vertices variables to make a .mat file of the 3D model which can be resized. I have been advised to use the vertices variable to create a wireframe, then to define everything inside the frame as 1 and outside the frame 0, and then finally save that as a .mat file.

Could anyone please advise a simpler way to do this? Please see that I am not an expert user of matlab, so an easyto understand approach is highly appreciated.

Thanks.

Salman
