This week I have been setting up the ASUS Xtion Pro Live Stereo RGB camera to be used along with an open source SDK known as OpenNI for quick prototyping and 3D motion/depth sensing.

As the title suggests, this is just a quick update on the 3D printing project I’ve been doing this year. First, after multiple failed attempts to print the Perko knots attached to pegs for the praxinoscope, I have finally created a model that passed all of Shapeways’ tests! The link to its page is here. Here are […]

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 […]

This past week Dr. Bowers and I met in order to come up with some ideas as to how to move forward with our problem of comparing meshes and/or images for error detection. Essentially, we were able to address some problems we’ve been having with some new ideas.

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 […]

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.

In the summer of 2015, I did a research project characterizing the critical groups of the Rook’s graph and its complement. I won’t be talking much about that specific project here – instead, I just want to look at the structure of the Rook’s graph. The Rook’s graph is a specific type of chessboard graph. […]

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 […]

I’ve made some progress in the past week with getting a implementation of OpenSfM running on my own machine and finally have done so. I ran a couple of test 2D images through the reconstruction pipeline with moderate results. So, I thought it was time to run some actual 3D printed material through it.
