Algorithm to find the edges of tetrahedra meshes
<p>I have a few thousands of tetrahedra meshes that is generated for modelling. I have the vertices and surfaces information which are indexed into two matrices which some are related. The nodes of surfaces are linked to the vertices' matrix. I want to find which vertices are connected to each other to form a tetrahedra. Is there an algorithm to detect the connectivity of the vertices that formed edges of a tetrahedra? </p>
