Isosurface function - 3D cooridnates

Hi everyone, I am using Isosurface function to reconstruct 3D volume by using 3D array of size 225x230x241 double. Following is the picture of image I am getting as a result. Isosurface function consist of a struct function which contains the vertices and faces of the volume. I just want to ask what information does this struct contains. These faces and vertices represents the complete volume or just the boundary of the object? (I am interested to find out the complete 3D coordinates of this image)

Kindly guide, thanks.

Hi,

I did similar like things sometime ago. The triangulated faces and vertices are represent on the surface outer boundary of an 3d object. These are closed surface so you can calculate the volume and surface area as well. You can use these vertices to find 3d coordinates but all will be on the surfaces.
