About Me: My name is Shane Transue and I am currently a Research Fellow (GAANN) and Ph.D candidate at the University of Colorado Denver (UCDenver). I currently have 14 years of programming/design/development experience and 6 years of research and development experience through the University of Colorado Denver. On this website I document my personal research, graphics research in association with UCDenver, and various independent projects. I currently work with Dr. Min-Hyung Choi in association with: The video below was presented at the grand opening of the Comcast Center at UCD on March 2. This video provides insight into the objectives of the center and the people involved.

I received my M.S. from the University of Colorado Denver in Computer Science with a research focus in Computer Graphics and Physical Simulation. I received my B.S. from the Metropolitan State University of Denver in computer science with a minor in mathematics. My research focus includes physical simulations of deformable bodies, physical simulation, animation, usability, software engineering, interactive tool design, and 3D scanning. In addition to these core research topics, several of my projects explore the fields of artificial intelligence, programming language design, human computer interaction (HCI), and scientific visualization. The deployed projects displayed on this site are either developed independently, in coordination with a university (MSUD | UCD) or in cooperation with private industry: Gamma Two Robotics | Laser Technology Inc. (LTI).

Recent Research Projects: Many of the projects listed below are in correspondence with the University of Colorado Denver Graphics Laboratory. For various projects, select videos are provided below. To see details about each project they are listed in the Graphics Lab Research page.

Non-contact Tidal-volume Estimation: Breathing volume measurement has long been an important physiological indication widely used for the diagnosis and treatment of pulmonary diseases. However, most of existing breathing volume monitoring techniques require either physical contact with the patient or are prohibitively expensive. In this paper we present an automated and inexpensive non-contact, vision-based method for monitoring an individual’s tidal volume, which is extracted from a three-dimensional (3D) chest surface reconstruction from a single depth camera. In particular, formulating the respiration monitoring process as a 3D spacetime volumetric representation, we introduce a real-time surface reconstruction algorithm to generate omni-direction deformation states of a patient’s chest while breathing, which reflects the change in tidal volume over time. These deformation states are then used to estimate breathing volume through a per-patient correlation metric acquired through a Bayesian-network learning process. Through prototyping and implementation, our results indicate that we have achieved 92.2% to 94.19% accuracy in the tidal volume estimations through the experimentation based on the proposed vision-based method.

Painting-based 3D Point-cloud Alignment: The process of aligning or performing registration between arbitrary 3D point-clouds including incomplete data, large distributions of errors, sporadic errors, and low resolution range images in an open problem within three-dimensional scanning and modeling. The implemented painting-based methodology builds on existing 'point-based' methods for the registration of arbitrary point-clouds through an intuitive interface for compiling large sets of range images into a consolidated model for surface extraction. An overview of the process illustrated in the video below is as follows: (1) a set of independent unaligned 3D scans are loaded into an alignment editor, (2) the corresponding regions of each pair-wise point-could comparison are identified using a painting-based interface, (3) each pair of scans are pair-wise aligned, (4) the pair-wise alignments are compiled into a final alignment (mathematical transformation or alternative global alignment technique can be employed (SLAM). The result is a reconstruction of the scanned 3D model. Painting-based alignment software implemented: SxFramework. The video on the right illustrates the implemented software (Scanix) performing a surface reconstruction of the surface of a material that has accumulated over time.

StruXturE: Physical simulation and free-from puzzle building game. This game introduces an intuitive interface for directly interacting with physical objects within a game for solving puzzles. This game was developed using the Unreal Development Kit (UDK). All of the core game mechanics have been implemented from scratch to provide a unique interface for interacting with physically simulated objects through a 3rd person perspective. All of the game assets including meshes, textures, shaders, levels, UI, and environments are original content. The two implemented game modes are driven by interacting with physically simulated objects within the world to build or construct a structure capable of holding the game objective objects. Within each level there is a designated goal zone (bright green volumes) and set of goal objective objects (bright green cubes). The objective is to get all of the green cubes within the green goal zones through connecting various models together through stacking or pivot joints.

Interactive Editing of 3D Deformable Animations: Precisely controlling the behaviors of three-dimensional deformable objects represents one of the continued problems within 3D computer animation for physically-driven deformation. The implementation of the Masters Thesis: Sx Animation Studio provides an intuitive and interactive set of tools for controlling the behaviors of simulated deformable objects in real-time. This animation editing interface provides intuitive controls for bending, twisting, compressing, and stretching simulated deformable objects. The videos below illustrate an example of introducing artificial wind resistance to a simulated cloth model using a bend control metaphor (left). The (right) video also demonstrates how this approach can be used to modify existing animations of deformable objects to provide slight modifications of localized deformation behaviors using a twist control.

Geometric Optimization of FEM-based Simulations: The following videos provide an illustration of how the geometric composition of a Finite Element Model (FEM) can influence the resulting deformation behavior of the object. The (left) video below illustrates a slight deformation behavior based on a low-resolution tetrahedral model. The (right) video below illustrates the same model with a higher resolution; however the resulting deformation behavior is drastically different. For both of these simulations, the FEM constants: Young's modulus and Poission's Ratio are held constant. This illustrates the impact of the geometric composition of the models resulting deformation behavior. This research established the basis for the publication: Deformable Object Behavior Reconstruction Derived through Simultaneous Geometric and Material Property Estimation.
