Aqueti: Ultra-high-resolution security-camera solutions

Aqueti is developing ultra-high-resolution (>10X digital zoom out from single-pixel display size) cameras for security and other markets.  ReliaSolve is working with them to develop the GPU-based decompression, tiling, rendering, and re-encoding portions of the pixel pipeline to enable viewers to pan, tilt, zoom, and move in time in a seamless view of the world.

Grace Boulevard

“Grace Boulevard” is a song that was inspired by time spent on the board of directors for Pharaoh’s Daughter, a 501(c)(3) non-profit organization that watches infants born to incarcerated women until they are released and then provides life skills, parenting skills and job skills training. The song aims to capture both the challenges facing Mom and […]

VR Concepts Illustrated Using OSVR

Published as chapter 32 of the book VR Gems (William Sherman, editor), VR_Concepts_Illustrated_Using_OSVR describes the technology required to develop effective immersive environment systems. The immersive nature of virtual and augmented reality systems engages the human visual system in ways that require wider field of view and lower latency than other 3D computer graphics systems to provide artifact-free rendering […]

OSVR

The Open Source Virtual Reality (OSVR) initiative, together with the RenderManager module from Sensics, enable immersive head-mounted or through-the-window interaction with 3D geometry.  The system runs on Windows, MacOSX, Linux, and Android and supports rendering in Direct3D, OpenGL, and GLES (including pre-emptive direct-mode rendering on hardware that supports it). These tools were used in constructing […]

Scientific Visualization Workshop

ReliaSolve offers a full-day hands-on training workshop in scientific visualization, including 2D scalar fields, 3D scalar fields (volumes) and vector visualization.  It includes both perceptual-psychology-based theoretical content drawn from the UNC Visualization in the Sciences graduate course and hands-on visualization using freely-available toolkits.  Participants receive USB drives containing all materials, software, and sample data sets. […]

VRPN

The Virtual Reality Peripheral Network (VRPN) was developed at UNC Chapel Hill by Russ Taylor and has been widely adopted in industry and academia, receiving contributions from scores of developers and device manufacturers. This cross-platform, multi-device interface forms the basis for device interaction in OSVR.

RedBud Labs: Blood Clotting Diagnostics

ReliaSolve co-founded and continues to work with Redbud Labs to develop control systems and analytical tools to determine clotting time, stiffness, and other characteristics of blood clots in custom microrheometry systems.  Current work involves porting the Windows-laptop-based control system to run in an embedded Linux board within the next-generation clot analyzer and extending the single-channel […]

AQT: Accelerated X-Ray calculations

ReliaSolve worked with Applied Quantum Technologies on a brief project from March-May 2016 to accelerate maximum-likelihood calculations to solve for the objects causing a specific pattern due to Bragg scattering in prototype X-ray screening machines for airport baggage. The original OpenCV-based calculations were several orders of magnitude too slow to be useful in the field.  Through the […]

“Latent” Arduino-based latency tester

The ReliaSolve Github page hosts an open-source Arduino-based latency tester project, Latent.  It includes build instructions, Arduino code, and CMake-buildable projects to estimate the input-device latency and motion-to-photon latency for a VR application. It also includes a CMake-buildable project to estimate the rendering latency (render command to photon) using the Sensics/OSVR RenderManager rendering system. Latent […]

Visual Common Ground

Reliasolve started working with Dr. Robin Murphy, the director of the Center for Robot-Assisted Search and Rescue at Texas A&M University, in June 2015 to develop a Visual Common Ground environment to display 3D terrain models reconstructed from drone fly-overs to provide a space for disaster responders to discuss and plan. The initial goals of this project are: (1) […]
