Inferring Quality In Point Cloud-Based 3D Printed Objects Using Topological Data Analysis
Assessing the quality of 3D printed models before they are printed remains a challenging problem, particularly when considering point cloud based models. This paper introduces an approach to quality assessment, which uses techniques from the field of Topological Data Analysis to compute a topological abstraction of the eventual printed model. This abstraction enables investigating certain qualities of the model, with respect to print quality, and identify potential anomalies that may appear in the final product.

We introduce an approach to calculating join tree that combines three strategies, pruning, spatial-domain parallelization, and value-domain parallelization, to parallelize join tree construction using OpenCL.

Point Cloud Slicing For 3-D Printing
This paper revisits a more than half-a century-old problem: slice a free-form object into layers for manufacturing. A point-based approach is taken that would have been prohibitive even a decade ago.

In this paper, we perform a
feasibility study for applying topological data analysis and visualization techniques never before tested by the ALMA (Atacama Large Millimeter Array) community. Through techniques based on contour trees, we seek to improve upon existing analysis and visualization workflows of ALMA data cubes, in terms of accuracy and speed in feature extraction.

In this paper, ten key challenges and their implications for CAD cyber education are discussed. The purpose of this paper is not to provide a dismal outlook for cyberlearning, but to incite discussion, research, and development into these areas with the anticipation of a viable and attractive alternative to traditional classroom education.

In this paper, we propose a new framework to implement visualization peer review in the classroom to engage students. This framework can be customized for incremental and double-blind review to inspire students and reinforce critical thinking about visualization.
