Abstract

This paper describes the design, construction, and evaluation of a learning module on projective geometry, 3D object reconstruction, and the 3D printing process. This module was developed while the author was a participant in an NSF Research Experience for Teachers program at Texas A&M University at 2014. The module utilizes cost-effective hardware and software tools to provide interesting hands-on experiences for high school students. Students are first taught to apply projective geometry concepts by using cameras to capture images of a scene and then using those images to calculate the location of a given object within a defined space. Once they understand 2D projective geometry concepts, they learn to use Autodesk’s 123D Catch software to reconstruct 3D objects in a planar environment. The process involves using digital cameras to capture images of a selected object at various angles and distances so that projective geometry calculations can be used to create a 3D model of the object. The 3D model can be post processed into a OBJ file, which can then be sent to a 3D printer to make a physical 3D plastic part using PLA or ABS materials. Pre and post-tests and an opinion survey were used to evaluate the effectiveness of the learning module. There was a statistically significant learning gain and students indicated that they greatly enjoyed the hands on experience as well as learning the subjects.
