Student Post: OpenSfM Revisited, Epipolar Geometry, and Possibility of Rendering

Greetings, I've continued to delve into the OpenSfM configuration files to attempt to get denser meshes without much promise. The meshes seem to be similar; however, with the yellow spiral I did receive a less distorted image that could be on the road to where we want to be. The figure is shown below: So …

Student Post: Automated Detection of 3D Printer Failures Using Structure for Motion and Computer Vision

The goal of this project is to provide more effective mechanisms for error detection of 3D printer failures through the use of ‘structure for motion’, computer vision and computational geometry. Furthermore, first steps in order to achieve this goal is to determine what actual constitutes an error and what types of errors the application will focus …

Student Post: Conversion of Graph to Solid Complete

Dear Reader, This past week I have read over the official OpenSCAD documentation and achieved a limited but sufficient understanding of the OpenSCAD scripting language. To the Sphere Packing software, I have added a new file output for the graph edges as well as a file output for the mesh triangles. Unfortunately, since it doesn't …

Student Post: First Steps Toward 3D Printing Meshes Generated By Sphere Packing

Dear Reader, A major goal of my Sphere Packing research is to actualize the mathematics and computer models into novel techniques for the mesh generation portion of the 3D printing process. To this end, we need a way to complete the full process starting from an STL model of a 3D object and ending with …

Student Post: New Lattice Structure and Other Ideas Going Forward

Dear Reader, Since the last time I posted, I have added the ability to generate a different lattice structure to the Sphere Packing software. This new lattice structure is called the hexagonal close packed (hcp) lattice. It is one of the tightest ways to pack equally sized spheres, with the other way being the face-centered cubic …

Student Post: A new way of generating infill meshes for 3D printing objects

Dear reader, I wish to propose a new method of generating new infill meshes for 3D printing objects. However, let me first give a brief background. Over the summer I worked as a software developer at Oak Ridge to create a suite of tools that apply the mathematical concepts of Circle Packing to generate graphs …
