By creating a velocity function that moves the vertices of an existing tetrahedral mesh towards their respective closest points in the cloud, we create a final surface that bears the likeness of the cloud itself, while not requiring any information as to the original mesh. The reconstructed surface is resistant to fracturing and webbing, and is able to connect nearby vertices while keeping a clear mesh interface boundary, which prevents the intersection of faces from occurring. We demonstrate our implementation with several examples derived from common .obj files and discuss the strengths and weaknesses of our approach with respect to each.","abstract_html":"We present in this thesis a modification to the deformable simplicial complex method that allows it to reconstruct surfaces given only a point cloud extracted from a Wavefront .obj file.
