Hi All,
I have an STL file that contains many many small sized particles. I am wondering if there is any way to calculate the total volume of the STL file without estimation (i.e., without using the alpha shape)? Is there any specific software that can do this?
The common software to read the STL file have a way to detect the connectivity of triangles in the STL file because they can show the particles separately. Is there any way to extract these connectivity in MATLAB?
Thanks.

You can read coordinates and nodalconnectivity from .stl file using stlread. To get the volume refer:
