This paper presents the integration of an Octree modeller, an assembly planning system, and a robotic cell to build approximate prototypes directly from 3D model data. The integration demonstrates the feasibility of an assembly based rapid prototyping approach referred to as OcBlox, which approximates Octree representations of 3D models with “Blox”. These cuboid units are automatically assemble...

A cube is one of the most fundamental shapes we can draw and observe from a drawing. The two visualization methods commonly applied in mathematics textbooks education are axonometric perspective representations. However, what see drawing really or only general cuboid (i.e., polyhedron with different edge lengths). In this experimental study, 153 first-year ( 19–20-year-old) students, two-thirds...
