A generative grammar for 2D manufacturing of 3D objects
… to engage with the superficial aspects of the objects they design and 2. The symbolic 3D environments of current design software are the ideal medium for design because they hide from the user the contingencies of physical matter. I examine these assumptions and the potential of a generative …

HandsOn : a portable system for collaboration on virtual 3D objects using binocular optical head-mounted display
… often have to collaborate remotely on 3D content, especially in fields such as urban planning or architectural design. We propose HandOn, a portable system for collaboration on virtual 3D objects. HandsOn leverages the recent advances in optical head-mounted display and finger tracking …

Generative adversarial modeling of 3D shapes
Given a 3D shape, humans are capable of telling whether it looks natural. This shape priors, namely the perception of whether a shape looks realistic, are formed over years of our interactions with surrounding 3D objects, and go beyond simple definition of objects. In this thesis, we propose two …

Object Modelling by Example
… we develop a number of methods for modelling 3D objects by example. Jump maps provide fast and flexible reuse of texture imagery in object modelling. Geodesic fans extend the local statistical techniques forming the basis for traditional image-based data-driven methods to 3D surfaces, and …

Development of a novel toner for electrophotography based additive manufacturing process.
… to conduct feasibility study of producing 3D objects by printing thermoplastic elastomer using electrophotography technique and thereafter sintering the whole layer using infrared light source .The term Selective laser printing (SLP) has been coined by the author for this new process. This …

2d Material Inks for Printed Electronics
… little work has been done to print on conformal 3d objects. Conformal printing is an attractive and emerging field, which can enable the deposition of specific electronic features, such as sensors and circuits, directly on to 3d objects. Functional ink deposition on 3d structures is not a trivial …

First Principles of Line Drawings
… for creating line drawings from photographs or 3D models. Current methods often rely on high quality paired datasets to automate the creation of line drawings. We observe that line drawings are encodings of scene information that convey 3D shape and semantic meaning. We bake these observations …

Improving Vision-Based Robotic Grasping for Enhanced Comprehensibility
… developed on orthographic images of prismatic objects with complete object information. The insights gained from the implementation are used to extend the three-step model to perspective depth images of 3D objects with incomplete object information. This extension includes probabilistic CNNs …

Robust Computer Vision beyond Lₚ Adversaries
… introduces a novel simulation-based framework, 3DB, designed for experimenting with arbitrary and semantically preserving perturbations on physically accurate 3D models directly instead of 2D images. The utility of this framework is demonstrated through its ability to diagnose and enhance the …

Coordinating construction by a distributed multi-robot system
… algorithm for the coordinated assembly of 3D objects that consist of multiple types of parts, using a networked team of robots. We describe the algorithm and analyze its stability and adaptation properties. We partition construction in two tasks, tool delivery and assembly. Each task is …

How To Pack Anything
3D printers can make anything, from household tools to rocket engines, so long as the models can be packed into a given enclosure. The denser the packing, the more efficient the print is. Unfortunately, modern packing research has struggled with complex shapes and even proprietary packing software …
